Equipment wire by b111yboy71 Seaman   Posted: 9 days ago
Hello, try looking for old 25way data cables at your local car boot sale. The cores are multi-coloured and very thin. Most LEDs only use a breath of current to drive them so you won't start a fire! Here's a tip about dropper resistors for LEDs: put them at the power supply end where you can tie them down securely. Also, the formula for finding the resistance you need is: R equals Volts(supply) minus Volts needed by LED (Vf) divided by the required LED current (If). So, say 12V supply, 2V LED wanting 15mA = 12-2=10/.015 = 666.667, so you'd use the nearest value above, which would be 680ohms. Easy! The size of the resistor in watts/milliwatts is found by I(current) times E(volts), so 10X.015=.15W, or 150mW. Hope I'm not teaching an old sea dog new tricks! Starting a new Firefloat - oh boy.😲

Spraying Again....... by RNinMunich Fleet Admiral!   Posted: 17 days ago
Hi Neville, Check out my Sea Scout 'Jessica' renovation blog for how to achieve good paint finish! 'Wet n dry' is the ONLY way to go. Right from the priming stage. It stops the 'riding' you describe and the generation of flying dust which is anathema to any paint or varnish finish, but you do have to clean and re-wet the paper and the object you are sanding from time to time!!! Any mistakes at that stage will carry through to the top coats and still be visible 😡 Don't quite understand how you created 'mouths'. I'm wondering if you sprayed too close and/or too heavy!? Your apparently exorbitant paint consumption seems to hint at this🤔 For the record; I started with 240 on the primer/filler for my Sea Scout and worked up through 400, 600, 1000, and 2000 and 3000 for the final top coats and deck varnish. All 'Wet', with a few drops of liquid soap added at the top coat stages, i.e. from the 1000 stage. At the end I polish with a mild cutting polish 'Anti hologram' they call it here, from the auto industry. Tedious I agree and a generous dollop of patience is required (the 'Secret Ingredient' I have often mentioned here 😉 But when you see the result it warms the cockles and makes it all worthwhile.😊 Happy spraying, cheers, Doug 😎 BTW; for the blue on my Sea Scout hull I used a 400ml rattle can for several coats (more than three in the end) and there's still some left ! BTW2; For masking I use Tamiya tape for nice crisp edges. Fill in behind that with 'normal' fine masking tape and newspaper.

Rudders and Propellers by RNinMunich Fleet Admiral!   Posted: 24 days ago
BTW; I copied your above massive text block into a document file and split it up into paragraphs so I could see where you're at! My conclusion: so far so good BUT! You made the one classic mistake of many model boat / ship builders 🤔 You continued the prop shaft tube right back to the propeller and hence you had to make oversize struts to support them. This is fundamental wrong and creates unnecessary work.😉 On real ships, including the Schnellboote, the so called 'stuffing tube' is JUST THAT, it 'stuffs' the shaft through the hull and includes stuffing glands to prevent the ingress of sea water. Outside the hull ONLY the rotating shaft itself continues on through the bearing in the support strut and to the prop. See attached pics of my HMS Belfast as an example. There was actually no reason for you to make oversize strut bearings, simply bushes to match your prop SHAFT not the tube would have been correct. Inside the real ship there is also NO TUBE, only bearings at suitable intervals. They look like gigantic versions of the big ends in your car. Imagine on really big ships, carriers, container ships, bulk tankers etc, with shaft diameters of 1metre or so how big the 'tube' would be, how much weight that would add and how difficult it would be to service and maintain! I've often noticed in posts here that folk confuse shaft and tube, often referring to the whole assembly as 'the shaft'. For convenience we modellers use prop tubes, who wants to fiddle about making a row of internal shaft bearings no one will ever see and will most likely never be really concentric? The downside is that continuing this 'convenience' outside the hull is wrong, adds weight and detracts from the scale appearance of the model. 😭 OK, it's 3am here now so - orf me 'obby 'orse and up (in my case down!) the wooden stairs to Bedfordshire, G'night all, cheers, Doug😎 Re shaft length: What fits fits, what don't don't! Such a question is like asking 'How long is a piece of string?'! If all three motors abreast won't fit you have to decide if the central motor should / will fit fore or aft of the outer motors. Then measure / adjust the shaft length accordingly. Before you start fitting the centre motor check what length shafts are commercially available and adjust your motor fit to suit. Otherwise make your own shafts and tubes to fit as required, as I've started doing cos I got fed up with 'standard sizes' wot don' wanna fit my ship. 🤔 G'night All, cheers, Doug 😎

A Tragic Tale Unfolds by NPJ Fleet Admiral!   Posted: 28 days ago
About a month ago I came across a wooden model of a Side Trawler by the name of ‘Maartje’ dating from what I assume was the Sixties. It is 84 cm long (33 inches) with a beam of 19cm (7.75 inches). The then owner had found it in a poor state and had reconstructed and painted to a large degree, but then turned to model trains. It was not known whether it was a ‘kit’ or ‘scratch’ built but he had however found it was a model of a boat, UK 223, lost with all hands in the North Sea off Texel (NL) in 1967 thought to be registered in Diss UK.. I am aware that such a tragedy is not uncommon with sea fishermen but I had never come across a model of such a boat. I had some time on my hands so I started to make enquiries and I was surprised how helpful people were. I had contacted the Dutch Embassy in UK, the Press Association in Netherlands and the Texel Tourist Information Centre. Within a very short time I had responses not just from those sources but also from others they had contacted. A major response was from the Embassy with the names of the crew of five, some were never recovered and important, was information from the Harbour Master of the Port of Urk, Netherlands confirming the boat was registered there and who then contacted the son of the captain of the ‘Maartje’ and gave him my contact details. I am pleased to say the captain’s son Jauwk contacted me and we are now in frequent communication. So we now know the date of the loss, the sea area, weather conditions names of the crew and results of the enquiry. Also very personal and emotional information including the fact that two of the crew were father and son and that the captain’s wife was carrying his son, Jauwk at the time of the loss. You never know what this hobby may lead you into. NPJ.

Pretend deck planking by steve-d Lieutenant   Posted: 28 days ago
Thanks for the reply. Had already sussed the curved planks but think I will stick to a simple join to the king plank. Just bought some fibre tip pens 0.3mm which should do the job. So, seal and sand the ply first?...the ink would track into the grain otherwise. Doing it before fitting means you can bin it if not happy or turn it over and start again.

Another toy pond yacht???? by Colin H. Fleet Admiral!   Posted: 1 month ago
Well Martin, the cloth is full of small holes and when I tried to put them on the seams started to give way. Also I think there should be some lead attached to the keel, there are hole in it and a feint shading difference about an inch wide along the bottom edge both sides. Cheers Colin.

Rudders and Propellers by teejay Commander   Posted: 1 month ago
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.

Kingsmere Model Boat Club by Ray Sub-Lieutenant   Posted: 1 month ago
Sorry no photos ,but I remember back in the late 60's early 70's spending some enjoyable Sunday afternoons sitting by the pond with my wife and children watching the straight running events against the Victoria club I believe,so that and seeing a guy with radio control air sea rescue launch got me started building model boats something which I had last done as a nipper.Does the King's mere club still exist,last time I went by the pond a few years back it had shrunk in size and was very overgrown around the edges.

Taycol Supemarine Resurrection by RNinMunich Fleet Admiral!   Posted: 2 months ago
Hi Colin, re your post in the scale speed thread- "I've got spare Viper marine 25 amp. So hopefully that will do. Also would you recommend a reduction box to give a fair scale speed as I don't want to overwork the motor." The Viper will be fine, I'll probably be using a little Viper Marine 10 on my Taycol Target in the fish cutter. Re gearbox: I doubt one is necessary. I would try to adjust the top speed more with the prop, mainly the pitch probably. The Supermarine is not particularly hi-revving, 4000 or so off load? If you reduce that your Sea Commander may behave more like a tug I suspect If you do decide to go that way PLEASE don't ask me to make it😁, I'm having enough trouble with the 1to1 gearing for my fish cutter😲 Good luck with bathroom and OP. Fingers crossed for you that the works DO start in 6 weeks (the bathroom I mean!) 😉 Cheers, Doug 😎

ASR 64 ft RNZAF HSL W1. R/C vid 3 by jbkiwi Sub-Lieutenant   Posted: 2 months ago
British Power Boat 64 ft RNZAF HSL scratch built 36" R/C model with twin systems including sound. Brushless 2000kv w/cooled (pump) in-runners, 30A car ESCs, 2200mah 2s LiPos remote lights etc. Started off in 1940, new with the RNZAF and had many modifications over the years till decommissioned, including machinery reduced to twin 671 Greymarine GMs (from the original 3x 500hp Napier Sea Lions) which were finally removed around 7yrs ago and replaced with a single 650hp GM Detroit 8v92T1 (still does 20 knots in its latest configuration ! - see this on the photo gallery of this model) This boat is in far better condition than the ex Phil Clabburn restoration of HSL 102 (he didn't have much to start with) and the hull has never had any major rebuild apart from being glassed to the W/L. Even today there is no way most people would pick it for 80yrs old. Those hulls never age! (ie some of the beautiful 'Whale Back' conversions still around)

motor sizeing by canabus Fleet Admiral!   Posted: 2 months ago
Hi Jim I used a Hobbyking D3548/4 1100kv , a car ESC (hk60A-SL)(electric fan on top for cooling), program card(HK PROG-CARD) and a 40mm 2blade prop(test out the one on the boat first). Battery a 3s 5800mah 30C Lipo. This is in my Sea Commander and gives a good turn of speed with a long run time. ESC set up:- 1 Cutoff Voltage for 3S=10.2 and 4S=13.6 2 Start Power Percent=5% 3 Advance Timing=4 4 Run Mode=2 5 Brake Force=1 6 Drag Brake Force=1 7 Neutral Range=1 8 Initial Brake Force=1 9 Reverse Force=1 Canabus

EarlyVosper M.T.B by Simplas by boaty Admiral   Posted: 2 months ago
Hi Onetenor Fuji 15 was a good glow engine which I don't think it is manufactured any more. Aero version max B.H.P was just below .40 when tested. If it was in a model aircraft it would have been around .20 to .25 depending on prop size which was good then for a small capacity glowplug . Marine versions when on the water put out a little less and the water cooled jacket was never as efficient as the finned cylinder jacket of the aero version. My two Aerokits boats, the Sea Commander and the Crash Tender are powered by single Speed 600 motors running on either 8.4 or 9.6 volt Ni Mh batteries. Performance is equal to that of marine diesel power such as the 2.46 Ed Racer and D.C 2.46 Rapier, the latter I used to watch in the fast steering events in the early 1960s at Fleetwood and Coronation Park in Crosby just outside Liverpool. Taycol powered versions would be obviously slower due to the additional weight were far more reliable and you did not have to put up with injuries from excessive use of a starting cord with kids watching and "extracting the urine" shouting "why wont it go mister".

Rebuild starts by MouldBuilder Captain   Posted: 2 months ago
Well it has been a while but I can now continue with the renovation. I have purchased most of the weaponry from Battlecraft and I must say that I am impressed with the quality. I will add pictures of these later in the build. I have started to prime all of the wood. Removal of the final areas of the original paint was a task but I got there in the end. I have applied sanding sealer and rubbed it down with 1000 grit wet and dry. It is starting to look and feel quite smooth. Have you built the 50cal guns yet Doug? I would like to buy some but I am concerned that they might be a little brittle for me to handle.🤔 Just a couple of questions to ask before I get on. Can I have suggestions as to who supplies good quality wooden kits to build at reasonable prices. I need to consider my next project. I want to buy a 0.8mm air brush for the larger areas as I am finding 0.5mm too small. I have my eyes on an Iwata HP-EP. This is for sale on ebay new at £122. Are there any suggestions for a better and or cheaper solution. Thanks.🤓

Now Coating and Matting by NPJ Fleet Admiral!   Posted: 2 months ago
On to Coating and Matting. (as well as sanding!) Now have at least finished all the stripping. Then did the ‘bright light in the hull bit’ 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 small………However, never too large now that’s interesting. Some materials purchased too large. Now have a life’s worth of Resin……(when does it ‘go off’ 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 bit……………. I now feel I started out with someone’s boat I had bought and now it has become “my boat” 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 the’ leaking boat’ 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 ‘chalky’ 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

54" long Cervia tug. by Novagsi0 Admiral   Posted: 2 months ago
See my boat harbour basically it was bought from pontins model makers festival 40 years ago the hull was made by a model maker. I have photos of his boat. He then produced hulls for sale from the mold and my Dad bought one he spent 9 years making a sealion 4 cylinder petrol engine and it was meant to be petrol electric hybrid generator. The start of the deck work was started by my Dad but was left unfinished for all this time. I have photos of the origional from slide photos my Dad took when I was 4 or 5.
