    H.M.S BRAVE BORDERER
    Thinking of a future project and decided upon another launch type vessel. My earlier Daman 4207 project gave an interesting model with good performance. The Brave class of FPBs (Fast Patrol Boats) caught my attention. Can remember the incredible performance they offered when entering service. Only two of the class were used by the RN, although variants were used by other navies. Have decided to use proprietary Glass fibre hulls in future as they probably cost little more than building from scratch using wood and
    resin
    . They give a robust and watertight hull, but one which still requires thought to complete properly. There are several companies that offer a โ€œPerkasaโ€ hull, a Brave class derivative with an almost identical hull. From previous experience have decided to limit my models to 40โ€ long, larger vessels become difficult to transport and handle. After much research considered the hull offered by MTB Hulls in Gibraltar met my requirements best. The inquiry to MTBHulls was well handled; the quotation acceptable, so placed an order. Was pleasantly surprised at the shipping costs. From the UK these often approach the cost of the hull, but from Gibraltar they are much more reasonable. Delivery only took 7 days.

    Mast assembly
    The supplied mast is of white metal and although OK it has a number of minus points for me. 1- The mast does not lend its self to being hinged. 2- It really needs navigation light on top and the supplied casting is not suitable for this. 3- wiring needs to be hidden, not easy with the casting 4- itโ€™s quite heavy Having said all that itโ€™s ok if you donโ€™t want my wish list. So on with the manufacture of a replica, I chose brass as the preferred material because itโ€™s easy to silver and soft solder. The main legs are made from 6mm round tube, which I squeezed in my machine vice to an oval shape to look like the castings, each of the ends were then squeezed again at 90 degrees to allow then to join to the cross mid-section. I made some brass inserts for the hinged end from 2mm brass sheet, which are bent by 25 degrees to allow the hinge mechanism to sit at 90 degrees to the cabin roof, these are drilled and tapped 8BA. These pieces actually block the end of the oval tube and need to have a 2mm slot milled in them to allow the wires to exit the tube; these are soft soldered in place later. Two feet were made from two pieces of 2mm brass plate the base plate being slotted to accept the upright and finally silver soldered together. (A point here for silver soldering is to use as little solder as possible and allow it to flow with the heat around the joint this means that no filing is needed. I find itโ€™s also good practice to quench the part when nearly cool to break the glass like residue of the flux then just steel wool is required to clean the parts). The feet upstands were then drilled 8BA clearance and the base fixing holes drilled the same size. The cross mid-section is made from 1mm brass sheet and is bent through 360 degrees whilst placing a 6mm round bar in the centre to create a hole for the top mast. A small wooden former was used as the piece was pressed together in the machine vice, this was then silver soldered to give stability and then filed to shape. This piece has to accommodate the wires passing through, so again a 2mm slot is milled from each leg location to the centre to create passage up to the top mast. The top mast is just stock tubing which then has a turned top with four 5mm holes machined at 90 degrees to accommodate the LED. This is a 5mm Flat top wide angle LED this will direct the light out of the four holes. Finally the cross piece, again stock tube with small ball finials at each end soft soldered in place and tapped 10 BA for the pulley blocks. All pieces now made, itโ€™s time to assemble the parts using a combination of soft soldering and epoxy
    resin
    . The wire that I used was silicon sheaved, and when I soldered the legs to the mid-section and lower hinge piece I made sure there was enough wire to pull through to check if the process had damaged the wire, but it hadnโ€™t. So having soldered the LED, the top was epoxied to the upper tube and the tube epoxied to the mid-section. Finally the mid-section was filled using Milliput but first putting some Vaseline on the wires to avoid them being stuck should I ever have to rewire the unit. Next the cross beam was added and epoxied in place. The bottom of the legs looked plain compared with the cast version so I have made some thin gauge brass covers with mock bolts as per the original. The whole assembly was cleaned up ready for a first coat of etch primer, and white primer, followed later with a final coat of appliance white

    Planking
    To make the hull water tight I use a product called z-poxy it's a 2 part product mixed in hardener and
    resin
    of the same amounts and I use a layer of fibber cloth and them the z-poxy smooth as best you can about 30 min. time to use and then let harden over night at least 24 hours and them you can sand and finish with filler if needed or some more coats of z-poxy sanding after each coat. Rick

    if you can stand the smell get some nappy liners and lay them on the hull then saturate with polyester
    resin
    ( + hardener). Once it set hard ( give it a week) you can sand it down with 600 used wet. Gives a smooth finish that is almost invisible. Sealed and hard wearing.

    Painting white metal
    Hi Roger, Metal fittings of any kind and white metal figures can be painted with either Humbrol type paint (enamel) or Acrylic paint,both will need their own primer, but remember๐Ÿ˜ฑ. you can paint enamel over acrylic, but not the other way (acrylic over enamel). Most of the fittings I get in my Deans Marine warships are white metal and
    resin
    , I use Halfords plastic primer (grey or white) then use acrylic paint from various company's to finish off. Hope this is of some help to you.๐Ÿ˜Š cheers Peter๐Ÿ‘

    Shroud for Model Air Boat
    Good Morning Chief Petty Officer. Glad to hear of some enquiry about air boats. I built a few of these in the mid to late 1960s and they were great fun. I powered them with engines like the Cox Babe Bee up to a Frog 150R diesel. All were free running of course and it was either a keep fit excercise to try and catch them before they hit the bank across the lake or in most cases there was always a good person ready to perform the "save".. Due to political correctness and the environment. the I.C powered versions are consigned to history . Them days we didnt have shrouds over the airscrews. Best method of securing a shroud is to use ZAP Z-Poxy
    resin
    . it is durable, water resistant and can be bought from good model shops and is a two pack. One bottle contains the
    resin
    and the other the hardner. its a 50/50 mix and you can purchase a range of them with various setting times. ๐Ÿ˜ŽBoaty

    Building the Cabin. Part 2
    Before the front window panels can be added to the cabin structure they need to be shaped to follow the curvature of the front deck as much as possible and then glued together with a reinforcing strip on the back of the joint. Unfortunately I made an error ๐Ÿ˜ก when shaping and jointing the parts and had to make some new panels from some thin ply that I had to hand using the old panels as a template, hence the roughly cut window apertures in the โ€˜photos. This was unfortunate but I feel better for the confession ๐Ÿ™. The new window panel was then glued and pinned to the front of the cabin assembly and left to dry while in the meantime I used my hot air gun to heat and bend the roof panel to the correct curvature. The roof panel was then pinned and glued in place on the cabin framework and when dry was trimmed with a small plane and the front window panel trimmed down to the roof profile. I added some additional framing and bracing pieces at the base of the front window panels and a โ€˜shelfโ€™ which will form part of the dashboard inside the cabin. I also added some extra framing and an end panel at the rear of the roof and a thin square bead was fitted around the base of the cabin sides and front to improve the appearance where the cabin meets the deck. Before adding further detail to the cabin I used some Z-Poxy finishing
    resin
    on the roof panel to strengthen it and provide a better surface for the paint finish which comprised of one coat of white primer, two coats of gloss โ€˜Appliance Whiteโ€™ and two coats of gloss lacquer, all with a thorough rub down between. When all the paint had dried and hardened I gave the exterior of the cabin a first coat of โ€˜Antique Pineโ€™ stain. Next I will add some detail to the deck.

    Rubbing fenders, more epoxy & hatch coamings.
    Mike. If I have to apply any filler to the hull then it's not ready for glassing, only once the surface is a perfect as I can make it would I apply the glass cloth and
    resin
    . With the sander I had to hot glue the 'captive nut' inside that locks the tilting table as it's not 'captive' by any stretch of the imagination ๐Ÿ˜ฒ. And I also removed the angle setting marker and re-applied it after setting a true 90 degree angle as it was a couple of degrees out. So after a little 'fettling', nothing that any competent person couldn't do, it works really well and accurately ๐Ÿ‘๐Ÿ˜๐Ÿ‘

    HMS BRAVE BORDERER
    Winter seems to encourage modeling, have spent many hours in hibernation working on the deck and superstructure details. A supplier offers a full set of Perkasa fittings, most of which would work on the Brave B. At one point considered buying a set. They are made in both
    resin
    and cast metal. Eventually parsimony prevailed, so only purchased a small number of hatch covers and other intricate shapes that would be difficult to make well. The items duly arrived and the quality is good. Was surprised by the weight though, so am pleased had embarked on making the other items from the usual materials. There should be an overall weight saving, along with a reduction in my surplus styrene and wood stock. One of the design tenants of the Brave class was flexibility. The vessel could operate as a MTB, MGB or Raider, or with a mixture of these capabilities. The weapon mountings were designed to allow armaments to be installed and moved around to suite the requirements of the role. Have reviewed many Brave class photographs trying to establish a โ€œstandardโ€ armament configuration, to reproduce. Not only does the configuration define the weapons installed, it also establishes the ammunition and flare storage cabinet arrangements. Eventually decided upon the 2 x 40mm Bofors gun arrangement with 2 x 21โ€ torpedoes and 4 x extended range fuel tanks. The model is now essentially complete. No doubt as I keep examining it will add further small details and refinements. Only disappointment so far is that it does not achieve the original weight target of 6 lbs, it is 9.5 lbs. The 6 lbs may possibly have achievable using one screw and motor etc., but once three are installed, not likely. The real test is when finally back on the water. Will close this blog then with a concluding report.

    Rubbing fenders, more epoxy & hatch coamings.
    With all of the deck planking fitted I can now fix the rubbing fenders to the hull where the deck meets the hull sides. These are made from 6.5mm x 5mm obeche strip steamed and bent to shape and fixed with 30 minute epoxy, unfortunately the strips are not quite long enough to do this in one piece even with the rear rubbing fender in place at the stern so a join has to be made which I hope wonโ€™t be too conspicuous. The fender tapers in height from bow to stern and the piece that runs across the stern was made from 5mm x 5mm obeche. All the fenders were โ€˜pilot drilledโ€™ for the pins that held them in place while the glue set. The complete hull was then given a further two coats of epoxy
    resin
    with a rub down between coats and a final โ€˜polishโ€™ with 240 grit paper used wet. The resulting finish is perfectly smooth and ready for paint. The front and rear hatches were fitted with the coamings that will hold the hatches in place. The rotary disk sander that I bought from Lidl is certainly proving to be very useful in shaping small parts at this stage of the construction. I note that itโ€™s back on sale now (Feb 2019) so if you have the opportunity and ยฃ30 โ€ฆ.go buy yourself one! The next stage will be to assemble the cabin.

    Motor, mount & prop-shaft.
    The prop-shaft, coupling and motor mount that I ordered from ModelBoatBits has arrived so it seems a good a good time to make up a supporting wedge for the mount to fix to. I do have a rigid brass motor alignment aid that I used when building the Crash Tender but do you think I can find it in the workshop?....nope! ๐Ÿ˜ก I expect it will turn up when I need it least! ๐Ÿคž Not wanting to waste time I used a length of heat shrink tubing over the motor coupling to make it as rigid as possible, a trick I had seen done elsewhere, and this enabled me to position the motor on its mount in the desired position and measure the angle that the mounting wedge needs to be made to. I used an offcut of beech that I had in the workshop which I cut to size and then shaped it on the rotary sander that I bought in Lidl, fantastic piece of kit !!. The wedge was then drilled to take the nylon motor mount and also the fixing screws that pass through the beech block, through the balsa base of the box and into the ply reinforcing plate that I put in during early construction of the hull. After cleaning up the hole through the keel the prop-shaft was keyed with some abrasive, smeared with some epoxy and then pushed through to mate with the motor coupling. I used the excess epoxy
    resin
    around the shaft inside the hull and used some packing tape to stop it running out when I inverted the hull to seal the lower end. A quick spin on the motor confirmed that the alignment was spot-on and the hull set aside while the epoxy set. The next step will be to plank the deck.

    Glassfibre cloth & epoxy
    resin
    I used glassfibre cloth and epoxy
    resin
    successfully when building my 46โ€ RAF Crash Tender and I chose to do the same with the Police Boat. See: https://model-boats.com/builds/view/23951 for the Crash Tender blog. The application of the cloth and
    resin
    serves to strengthen the hull enormously and produces a completely watertight hull, and after additional coats of
    resin
    are applied and sanded between coats resulting in a surface that is absolutely smooth and the perfect substrate for the subsequent paint process. With the benefit of my previous experience and greater confidence working with these materials I used a โ€˜fastโ€™ hardener with the
    resin
    which gives a working time of 30 minutes and a much shorter curing time where previously I had used a 90 minute โ€˜slowโ€™ hardener. The basic process is to cut the cloth roughly to shape with a good margin of overlap and then use masking tape along one edge so that after the
    resin
    has been brushed onto the hull the cloth can just be lifted over onto the
    resin
    . I then lightly brush the cloth into the
    resin
    and push the cloth into any tight angles, without any further
    resin
    on the brush, until the weave of the cloth is filled and there are no air pockets and the cloth is completely flat. At this point DO NO MORE as the
    resin
    will start to harden and any more fiddling with it will cause the cloth to lift and bubble, less is definitely more in this instance. The
    resin
    should cure completely overnight and can be trimmed with a sharp blade. I tend to cover a hull in five stages, as there are five โ€˜facesโ€™ to the hull and thus itโ€™s a five day process for me, this may be time consuming but I think the results are worth the effort. I will brush on two further coats of
    resin
    when the rubbing strakes and gunwales have been added, this will completely fill the weave of the cloth to create a nice flat surface but itโ€™s essential to rub down each coat after curing. All the materials were bought from โ€˜Easy Compositesโ€™ https://www.easycomposites.co.uk

    The bow blocks & outer keel
    The bow of the boat has a compound curve and to create the shape a single block of hard balsa is supplied in the kit, although in my pre-production prototype this had to be formed by laminating some pieces of thick balsa together to the required size. Rather than laminating up a single block separately I did the laminating and glueing in situ on the hull to ensure a solid tight block, and after the glue had cured I set about shaping it. Initially I used a razor saw to roughly remove the surplus at the sides and bottom and then began the process of shaping it to the final form. My sanding plate proved invaluable for the final stages of making the block flush with the hull sides. The underside of the blocks were very carefully shaped with a combination of the sanding plate and abrasive paper around a series large round formers. I was careful not to just use abrasive paper over fingers as this can create grooves and unevenness in the soft balsa. I had already created a concave shape in the bulkhead former F1 and with the ply bottom skins in place it was relatively easy to extend the contour into the bow blocks being very careful to ensure symmetry on both sides. A line was drawn on the blocks that extended the curve of the hull strakes to define the shape. I also used the outer keel as a template throughout the shaping process to make sure that I was not removing too much material. it would be very easy to remove too much material so it pays to do this slowly and carefully, checking all the time for symmetry. Finally when I was happy with the shape I formed a slight flat on the blocks for the outer keel to sit on, using a back light helped greatly with this, and the whole hull was given a light sanding with a detail sander. The prototype kit was supplied with keel components made from thick balsa which would easily be damaged in use so I recreated this in thick ply laminations to the required thickness and shaped it so that it was completely flat and square on the inner edges and with a curved profile on its outer edges. The keel was checked for fit on the hull throughout so that only a minimum amount of filler would be required to blend it to the hull. It was fixed in place with epoxy adhesive and firmly pinned until it fully set and very little filler used to finish it. The kit, which is available now from VMW, includes a single piece bow block and ply keel parts as standard, which makes construction much quicker and easier. Iโ€™m glad that bit is over and Iโ€™m very pleased with the result. Next stage will be glass fibre cloth and epoxy
    resin

    1-35 Scale Schenllboot By TeeJay
    Hi all for the second blog report on the schnellboot I am going to go over the rudder a propeller shaft assembly in more detail. The first stage was to make the rudders which were made of brass ,and having taken note of what has been said about the increase in size needed for the kit by other members I have increased the size of the rudders by 50% so that they have more effect and hopefully the boat will be more agile .I fitted 3mm treaded rod on to the rudder and in a 4mm flanged tube to reinforce the brass rod. The second stage was to make and fit 5mm flanged tube in the location for the rudders in the boat, these were made to be above the water line and will be sealed in place to reduce the possibility of leaks. These were fitted to a rudder platform inside the boat which was fitted to the kit moulding for the rubbing strip that runs the length on the boat and secured by making
    resin
    blocks which were fitted with computer extension nuts. which were then superglue in place to secure the rudder platform. The rudders were then fitted in place and held in position with the tiller collars which were made from 8mm rod and fitted the tiller arms and locked in place with 3mm computer screws and ni-lock nuts, a connecting plate was then fitted to connect the three tillers together, I also fitted rubberised washers to seal the rudder tubes. The third stage was to make the propeller supports. The centre support was a direct copy of the kit part made of brass and fitted to the kit with a plate and screws (this plate and the rudder plate were made from galvanised steel) and will sealed with
    resin
    after the I test the boat for leaks. The port and starboard supports were made by taking the kit parts and cutting them in have along the joint line or mould seam this gave me a template ,which I used to make cross-section segments but I did alter the template by increasing the boss diameter to 10mm and extending the support legs so that the finished support could be fitted through the hull (the picture of these show the mk1 version where I forgot to allow for the 4mm prop shaft which has a 6mm tube) any way the boss of these segments were drilled out with a 7mm drill and a length of 7mm brass tube fitted through the boss to assemble the segments, all of which were coated in soldering flux at this stage of the assembly which were riveted at both ends to hold it all together during soldering, after soldering the supports were then filed to the size and shape to resemble the kit parts as close as possible and fitted to the hull using a superglue and talcum powder mix and then I cast
    resin
    around the extensions to secure the prop supports in place. The fourth stage is the propeller shaft housing for the centre propeller housing I place a brass rod in a plastic straw and place in position in hull and using
    resin
    I sealed the hull with the rod in place this gave me a pilot hole for the centre prop shaft after I removed the brass rod. For the port and starboard shafts I used the kit parts which had hole place when assembled, this when I reinforced the housings ,the centre housing I glue 2mm of plasticard on each side and for the port and starboard I made a brass tube shroud which covered the housings which left gaps between the kit part and the brass which was filled by casting
    resin
    in the gap this increased the diameter to 10 mm so that there were little chance of breaking throw with the drill and finished these off by fill-in the outside with body filler and sanded to shape and finish . I then drilled through the pilot hole in the housings using very long extended drills and a wheel brace ( if I had use a power drill the heat would have melted the plastic of the kit and may have caused problems) I drill the shaft housings out 6mm them filed them out with 6mm file so that I could insert a length of 6mm brass tube. After all this was done I fitted a flanged bush made from 7mm tube and 2mm brass plate turned to 11mm to the ends or the propeller shaft housings. And now it is time I must ask for some help could anyone advise me on the length of propeller shafts, I know I can use a 300mm shaft for the centre shaft, but port and starboard will have to be longer. and I also need advice on selecting the motors, I want to use 4mm prop shaft with 35mm propellers. Any opinions welcome.

    Hi Joe, In answer to your queries, Hull was built in the bread and butter system using deal sealed inside and out with coats of yacht varnish and painted using acrylic. Subsequent models of Wherries and Chinese Junks were plank on frame using 1/8โ€ balsa strips sealed with
    resin
    ,varnish inside and out, with again acrylic paint. Balsa easier to work with to gain experience - reasonable effectiveness both in carvel and clinker planking. All the best and good sailing. Gascoigne

    Rear deck continued
    The rear deck has a few features that need to be done to finish the deck. 1) The hatch part needs the magnets putting in to hold it in place, which requires the deck to be milled out to accept the magnets. Having milled the recess out in both the base and the hatch in four places the magnets can be epoxied in the base. Now these have been set in place the upper magnets can be placed on top of the base magnets to get the correct orientation and glued in place, but I made sure to place some silicon baking paper between the magnets so they donโ€™t accidently get stuck together (with epoxy). 2) The handles and recess to lift the decks out have to be milled out. Using a 2 mm slot drill I cut a 10mm x 5mm 1.5 mm deep recess in 4 places. Each recess has two holes drilled in the corners to accept the brass handles which will be epoxied in later 3) There are two drains at the rear of the deck. These were made from a machined piece of tube, which had vee groves milled in one end to accept a 1.5 mm brass rod in each, which were then soldered in place. After some cleaning up of the excess solder the underside was filled in using epoxy
    resin
    coloured black (with Graphite) to simulate a dark hole. The ends were then machined flat, polished, and finally epoxied into the deck. 4) Finally the foam tanks need to be secured, once again using round magnets this time , they are sunk into the deck and similarly the opposing magnets are sunk into the base of each foam tank, this gives a real sturdy fastening the tanks jump into position as soon as they are placed near their position. 5) The deck has had a number of clear lacquer coats during manufacture so now for a couple of final coats.

    Thanks R in Munich! The shapes of brackets under the rivets are cut out from a sheet of fibre glass. Depending on contour held in place with a dab of CA or the finishing
    resin
    , then topped with finishing
    resin
    . I have now to decide if I use the rivet method for the reset of the ship. The hull effect was via dabbing pva glue but some spread slightly and thus look over scale on some. 1mm ~50mm so a rivet head spreading to 2-3mm ~ 100-150 and I think a 6" rivet head might be unrealistic? What was ther likely rivet head size on such ships. Toby

    HMS BRAVE BORDERER
    Back to the build. Next milestone, to complete the superstructure and engine covers. The superstructure is essentially a cowl that supports the open bridge and serves as the air intake for the gas turbines. The engine covers fit into the rear of it. The superstructure is full of curves and will be interesting to make. Still trying to save weight, decided to make it out of glassfibre. Rather than first make a plug then a female mould and finally the cowl, wanted to try the technique of making a plug out of styrene foam sheet, then covering it in a glass fibre matt. Once the glass fibre is set, the foam is dissolved out using a solvent and the cowl remains โ€“ inshallah! To ensure the foam did not react to the glass fibre
    resin
    , painted the finished cowl with enamel paint before sticking the matt down. See pictures. What a mess! The
    resin
    had crept under the paint and into the foam dissolving it. When the
    resin
    dried the plug had shrunk slightly and had the surface finish of a quarry. First thought was to hurl it and start again, this time in wood. On second thoughts, wondered if the plug could still be used. Decided to build it up with wood filler and from it make a female mould, as originally intended. The cowl would then be made from the mould. Built the damaged plug up and sanded it smooth. As the plug would be covered in fibreglass, the surface finish was not critical. Brushed a coat of fibreglass on the plug and, after drying filled any defects with glaze putty and sanded smooth. Once the finish and dimensions were satisfactory, applied a thicker coat of glass fibre to the plug. This was again smoothed down, waxed with carnauba polish and then covered in mould release. From it the cowl was made. Picture shows plug, mould and cowl placed side by each. The cowl requires reinforcement; the fittings and various mountings then adding before installing. A trial installation showed that it fitted properly the deck and was accurate. A lesson for the next time is to make the plug and mould much deeper than the finished item. That will allow any rough edges, on either the mould or the component, to be trimmed off leaving a smooth fibreglass edge.

    Bristol pilot cutter mascotte
    Hello all this is my latest build of the Kingston mouldings Bristol pilot cutter 'mascotte' was purchased from a forum friend who no longer had time to build it. Sadly Kingston mouldings has now closed down. The first job was to glue the lead ballast into the bottom of the hull, this was done by using fibreglass
    resin
    then a couple of layers of fibreglass to seal the lead shot into the built in keel

    Rowen, here are a couple of things that may be of use to you (and others). The battery alarm will save you worrying about running out of steam as they can be set to beep at varying voltages to warn you of low battery, just put one on each batt balance lead and when one goes off (when an individual cell drops below the set voltage) it means start heading back. These can be picked up on Ebay for a few dollars. I use them on my planes as well and are audable from around 100m (these twin horns are the best) Secondly, re your ESC switches, these electronic switches (AliExpress) are great for this sort of thing (as long as you have enough aux switches on TX ) You can link them with a Y cable to work together or use them independantly for anything, (lights, pumps etc, - they can be operated by TX rotary switches as well) The ESC and 2000kv motor (HK) are the ones I am using in my ASR model and will work smoothly down to a crawl, the purple 1980 kv seems to have superseded these but I think they will be as good. The props are from Ali Express and are
    resin
    and available in L and R hand, are only a few bucks and perform perfectly while looking quite scale(ish). I painted them with an acrylic bronze which seems to have stayed on pretty well. Model weighs 2.8kg and will run at more than 10mph flat out with this set-up (using the 26mm L+R) props) which is silly speed and that's with 2x 2s 2200mah lipos (which will last till you get sick of it and still have 60% left) I was just looking at your Daman set-up and noticed the wiring method from the batts to the ESCs. You might want to make your batt to ESC connections direct to your ESCs (as per original ESC lead length)as your capacitors may get a thrashing (spikes) due to the extra length/ resistance you have there. There is a general rule that you don't lengthen the batt to ESC wiring without adding a 220mf capacitor of same voltage as the ESC for every 4"of extra wire length (ESC to motor - not so much). Might want to check this out in case you fry your ESCs You probably have thought of this but thought I'd mention it, 'just in case' Might help with your modulation as well. Have chucked in a vid of the HSL manouvering (first trials so wasn't perfect) and also the MTB (brushed) which I have just converted to a twin system (was twin but single Electronize unit) plus a sound unit. You may know that you can use as many RECs (bound to the same TX) for various purposes on the same boat (have run 2 boats together from the same TX) Might get you round the mixed brushless/ brushed problem with a bit of thought. Have you thought of changing your old HK silver 6DF TX to twin throttles, it's a piece of cake(as is the TGY 6x), just remove the aileron/rudder centering spring and make a friction plate as per throttle stick, and use the elevator channel as your other throttle. Set your ESCs and you can then use a twin system giving you perfect control. Saves a lot of hassle.

    The wheelhouse navigation light.
    This is a small item but very visible on the wheelhouse and since the standard for this item has been set I have to follow suit. So first of all get some 3mm blue LEDs ordered and then itโ€™s on with preparing the white metal body. I used by hand as suggested a series of drills increasing in diameter until 3.1 dia was reached but only 2/3 down the length from the front the smaller hole (1.5mm) was bored right through for the wires to exit. Arrival of the LEDs, first check the LED using my power supply, just over 3 volts seems to illuminate to the correct level. Next was to remove the shoulder on its plastic casing so the whole body does not exceed 3mm over its length and lightly abrade the outside to give a diffused light. Next cut the LED legs to 2mm from the plastic casing noting which is positive, next prepare the wires. I used Futaba servo wire cable 22awg which is very flexible and with the white signal wire stripped off leaving a red and black wire. These were tinned and cropped to 2mm and then quickly soldered to the appropriate terminal. Next check the LED still works! first hurdle over, I now needed to check the that when the LED goes into the body it doesnโ€™t short out so checking the diameter over the widest part which is over the soldered terminals this was 0.1 below 3mm. I decided that shrink sleeve was too thick so I mixed some epoxy
    resin
    and coated all around the terminals, this proved to be satisfactory in both non-conductivity and dimensionally. Now the final test, using some aliphatic wood glue I slid the LED into the body whilst it was illuminated as it was a tight push fit, bingo itโ€™s still lit โ€“ leave to set. I used aliphatic glue, as it would be easier to remove should I ever have to change the LED. The body still needs painting white but this will be done with all the other fittings at a later stage.

    Cleaning sails, toy yachts, etc....
    I did indeed use an abrasive polish on the cream paint, but as it was a very severe crack or two all along the hull, I injected
    resin
    in the crack and clamped it up as far as possible, then Milliputted in to fair it. This was between two strips of tape to prevent the spread of epoxy or Milli further than necessary. I managed to match the cream more or less and once I've put a coat of nice amber spar varnish on it'll look like the original when heeled and won't show at all when on display. Martin

    parts that were far too heavy, I made some aluminium planing wedges and various other parts to save weight.

    1-35 scale S100 schennllboot
    Hi all for the second blog report on the schenllboot I am going to go over the rudder an propeller shaft assembly in more detail. The first stage was to make the rudders which were made of brass ,and having taken note of what has been said about the increase in size needed for the kit by other members I have increased the size of the rudders by 50% so that they have more effect and hopefully the boat will be more agile .I fitted 3mm treaded rod on to the rudder and in a 4mm flanged tube to reinforce the brass rod. The second stage was to make and fit 5mm flanged tube in the location for the rudders in the boat , these were made to be above the water line and will be sealed in place to reduce the possibility of leaks. These were fitted to a rudder platform inside the boat which was fitted to the kit moulding for the rubbing strip that runs the length on the boat and secured by making
    resin
    blocks which were fitted with computer extension nuts .which were then superglue in place to secure the rudder platform. The rudders were then fitted in place and held in position with the tiller collars which were made from 8mm rod and fitted the tiller arms and locked in place with 3mm computer screws and ni-lock nuts, a connecting plate was then fitted to connect the three tillers together, I also fitted rubberised washers to seal the rudder tubes. The third stage was to make the propeller supports. The centre support was a direct copy of the kit part made of brass and fitted to the kit with a plate and screws (this plate and the rudder plate were made from galvanised steel)and will sealed with
    resin
    after the I test the boat for leaks. The port and starboard supports were made by taking the kit parts and cutting them in have along the joint line or mould seam this gave me a template ,which I used to make cross-section segments but I did alter the template by increasing the boss diameter to 10mm and extending the support legs so that the finished support could be fitted through the hull (the picture of these show the mk1 version where I forgot to allow for the 4mm prop shaft which has a 6mm tube) any way the boss of these segments were drilled out with a 7mm drill and a length of 7mm brass tube fitted through the boss to assemble the segments, all of which were coated in soldering flux at this stage of the assembly which were riveted at both ends to hold it all together during soldering, after soldering the supports were then filed to the size and shape to resemble the kit parts as close as possible and fitted to the hull using a superglue and talcum power mix and then I cast
    resin
    around the extensions to secure the prop supports in place. The forth stage is the propeller shaft housing for the centre propeller housing I place a brass rod in a plastic straw and place in position in hull and using
    resin
    I sealed the hull with the rod in place this gave me a pilot hole for the centre prop shaft after I removed the brass rod. For the port and starboard shafts I used the kit parts which had hole place when assembled, this when I reinforced the housings ,the centre housing I glue 2mm of plasticard on each side and for the port and starboard I made a brass tube shroud which covered the housings which left gaps between the kit part and the brass which was filled by casting
    resin
    in the gap this increased the diameter to 10 mm so that there were little chance of breaking throw with the drill and finished these off by fill-in the outside with body filler and sanded to shape and finish . I then drilled through the pilot hole in the housings using very long extended drills and a wheel brace ( if I had use a power drill the heat would have melted the plastic of the kit and may have caused problems) I drill the shaft housings out 6mm them filed them out with 6mm file so that I could insert a length of 6mm brass tube. After all this was done I fitted a flanged bush made from 7mm tube and 2mm brass plate turned to 11mm to the ends or the propeller shaft housings. And now it is time I have to ask for some help could any one advise me on the length of propeller shafts , I know I can use a 300mm shaft for the centre shaft but port and starboard will have to be longer . and I also need advice on selecting the motors , I want to use 4mm prop shaft with 35mm propellers. Any opinions welcome.

    HMS Campbeltown 1941, 1/96 scale
    Hi Steve, On my Manxman, a fast cruiser / minelayer, it was used to protect the deck where mines were dragged from the stores to the laying rails in the stern. Otherwise I've never seen extensive use of it on open decks. Mostly just in enclosed areas where there would be a lot of 'foot traffic'. In recent years (decades!?) I've seen blue, yellow and green versions inside the vessel, especially in the so called 'Citadel', a protected area which can be hermetically sealed against chemical or biological attack! ๐Ÿ˜ฒ The 'non slip' variants on the weather decks all seem to be paint /
    resin
    mixtures containing some sort of abrasive material. I don't think it is worth the effort you describe to depict corticene!! Cheers, Doug

I think I'd just put up with it as I couldn't stop modelmaking even if I wanted to. I did painting when we lived afloat for lack of space, but I didn't find it satisfying enough. Martin

    Thanks for the kind comments. Planking did take a couple of days but was not done all that neatly (just clamp and cyno) as I was glassing it later - it was all thin
    resin
    coated inside to seal it). Planking was just a hint at the original so you could just make out the planks through the glass. Have included a few more pics of the motors and interior which is not that flash but is unseen, (more for the fact that I had seen the original and was sort of putting down what I remembered from when I was 15) There is a small picture at the top left of the stairs which on the original, was a Photo from an HSL looking off the Stbd rear 1/4, to 2 64ft HSLs side by side climbing over its wake at speed The stair set is the original from the wheelhouse to wardroom, which has been kept and used again by the present owner (down to utility room in front of engine room) and still has the original 'POWER BOAT' rubber treads (not bad nick for 79yrs old!)

    Boat lifting eyes
    Boat lifting eyes As has been said by others the boat lifting eyes are a small detail but an important one, somehow when detailing gets in your head its difficult not to seek it out. Anyway, there are six eyes three on each side, which I presume, are for lifting the boat out of the water, unfortunately there isnโ€™t any detail on size so itโ€™s down to โ€œbuilders eyeโ€. I made the six in a batch, thatโ€™s to say I first made six identical pieces 10.5mm x 20.5mm x 2mm thick and drilled the hole in each then the six pieces fastened together with an M4 screw and then machined together to ensure uniformity and ease of production. I then skimmed them to final size 10 x 20 followed by milling the concave and convex radii on the top. I intend to sink the eye into the deck and secure using a brass pin sideways into the gunwhale stringers and epoxied into position. To ease fitting I made a small jig, which will allow a 2mm slot to be cut in the exact position on the deck along with a drilled hole at 90 degrees. Two small grub screws fasten the jig to the gunwale stringers while the slot and holes are machined. After all the slots had been prepared I then made all the foot rails that run along the edge of the deck from bow to stern, the first set I used the obeche supplied in the kit, however as they are in a place that could get knocked I decided to rework then in walnut. Finally I pre drilled all the foot rails ready for temporary pinning. Having all the components ready it is time to assemble with epoxy
    resin
    , using sparingly and making sure not to get any on the visible part of the brass lifting eyes and using pins to hold in position while curing. PS sorry about some of the picture quality but I didn't check them until after assembly

    Now Coating and Matting
    On to Coating and Matting. (as well as sanding!) Now have at least finished all the stripping. Then did the โ€˜bright light in the hull bitโ€™ to look for areas that needed patching. The major problem area was in the bow and that did not receive the light as it is a totally blanked off compartment. However, it was obvious from the outside anyway so, could I assume it was the only leak? Decided to put a fine matt over the whole hull, not deck, just to be sure of best chance of success. I can imagine what will be said here if it still leaks after all this! I had ordered some supplies ready for the next stage and drew up a plan view of the boat to help think through layout of electrics and other items. Made my usual mistakes about size. Some fittings purchased too smallโ€ฆโ€ฆโ€ฆHowever, never too large now thatโ€™s interesting. Some materials purchased too large. Now have a lifeโ€™s worth of
    resin
    โ€ฆโ€ฆ(when does it โ€˜go offโ€™ by?) Also have a lounge floors worth of tissue matting! Also Sandpaper. Now there is a mine field. So now I know a bit more about that and which way the numbers work! When I forgot to put the mask on, I had some of the crispest 'bogies' in years.............. No images posted! On the plus side, although I never wanted to get into this stripping sanding, filling sanding, sealing sanding, matting sanding, painting sanding, painting, sanding bitโ€ฆโ€ฆโ€ฆโ€ฆโ€ฆ. I now feel I started out with someoneโ€™s boat I had bought and now it has become โ€œmy boatโ€ for real! I am at the stage now where I have put some filler in and applied the first coat of Eze-Kote from DeLuxe Materials To use Eze-kote read stuff from RNinMunich on this blog or theโ€™ leaking boatโ€™ thread. Washes out of the brushes very easily. There is such as this ..... Youtube link - watch?v=yP05qv3QtUk RNinMunich or Colin H. and the like have bits of extra comment and experience that is always very helpful. BTW, after that finer sanding before first coat, I did the dust down and vacuuming bit but it still felt a bit โ€˜chalkyโ€™ so I gave it a wipe with Methylated Spirits. Now I realise that has water in it, so if anything goes wrong it could be blamed on that................. Having left the first coat to dry I started to cut out the light matt to apply after the next sanding. The matting I have is called Glassfibre Surface Tissue EGlass from FibreGlass Direct. A part of Tricel Composites (NI) Limited. Available internationally in lengths from a metre upwards, it is quite fine in weave so we shall see what happens. I have left quite a wide margin at the moment but may reduce that when I have tried using it! This is another first for me so plenty of room for mistakes............... Will need to cover with the matt in stages as I cannot get around all the boat without changing its position. Going for the bottom of the vessel and stern board first as I figure they are going to be easier than some of the other bits. Then will leave that to cure before moving the boat. Really worried about the joins/overlaps and how well I will cope with those, not to mention the curved bit! Started to look at electrics and layout for a bit of a change. I will post again when I have had the first battles with the matting! TTFN. NPJ

    Evenin' Neville, I told you you'd get the hang of it pretty quick. (It was either that or you'd burn the house down๐Ÿ˜ฒ)๐Ÿ˜ Seriously; I'm proud of you๐Ÿ‘ You had the guts to give it a go and you're learning fast ๐Ÿ‘ Hat off Sir! A few observations; (Colin might also have some at this point, had a very nice chat with him on the phone this afternoon - but that's another Encyclopedia Britannica!) #1 if the paint scraps are smoking the gun is too hot or too close, or moving too slow. Wind it down to 350 and see how that goes. Back up to ~400 if seems necessary. #2 Bow cracks; I see a bodge up there where someone couldn't bend the skin properly or, benefit of the doubt (In dubio pro reo!), maybe it was collision damage. Whatever; filler in a thin crack will always vibrate out again sometime๐Ÿ˜ก Try to get at the inside and seal it with two layers of fibreglass tissue well soaked in
    resin
    , EzeKote is what I used. Wait about 10 minutes before applying second layer. Then it should bond well with the first. When that has set (ca 20 - 30 minutes) then you can apply some fine filler from the outside. When set sand smooth and seal the whole hull outside with two layers of FG tissue. Sand smooth and if any bare wood appears apply wood sealer or EzeKote thinned with 10% warm water. Don't overdo the water or it takes yonks to dry and set - Yes, it happened to me๐Ÿค” Then continue with priming / finishing as described above; or look in my Sea Scout 'Jessica' blog for the fine details. The beauty of using EzeKote for all this is that you can get a whole hull done inside and out in one day and no mixing ratios to cock up๐Ÿ˜Š๐Ÿ‘ If it's any consolation to you; when I did all this on my fish cutter and PTB loads of filler went soft and fell out as well, and the 'goo' holding the prop shafts in my PTB as well. No sweat as I wanted to realign the shafts anyway! TIP: I removed all shafts rudders and any other protrusions in the way so there were no 'twiddly' bits left to make things awkward. Leaving the odd patch of sanded paint which is still firmly fixed to the wood is OK; as long as you can't feel a 'bump' with your finger tips and you are going to seal it with
    resin
    and primer anyway. Then it can't react with the new paint. Here endeth the 3039th epistle from Admiral Doug.

    Bit of a problem.............
    Evenin' Neville, For God's Sake (Whoever he may be) put the wire brush back in the drawer and save it for cleaning engine blocks๐Ÿ˜ฒ Use a heat gun and a scraper to get the paint off without destroying the wood. Like I had to do with my Gina 2 fish cutter and PTB hulls. Much less dust than trying to sand / wire-brush the paint off. That way will take you a month of Sundays anyway. The sand the hull flat and cover it with two layers of fibreglass tissue and
    resin
    . I used EzeKote, no mixing, no smell, sets in about 20 minutes and brushes wash out in warm water. ๐Ÿ˜Š Apply a final coat of
    resin
    . Sand flat and prime. The pics show these three stages for the cutter and the PTB. If the crack is bad reinforce it on the inside with a couple of layers of tissue and
    resin
    . Then give the whole inside of the boat two coats of
    resin
    . Take out anything that stops you getting down to the underwater hull and keel joints. That should fix your leak once and for all, strengthen the boat to help prevent any further hull damage if you hit something underway and give you a good base for the final colour coats.
