Glue
I think this is a subject that many of us have pondered and discussed. I where possible try to use a single material for a particular structure so that the adhesive used is the recommended one for that material be it wood, metal, plastic, or glass plus the many variants of each. Then comes the issue of joining dissimilar materials for example
styrene
to wood
styrene
adhesive, so a contact adhesive or a specific epoxy could be suitable. However now you should also consider the type of joint you are using and the resultant forces that will be applied to the joint as this will greatly affect the adhesive used. I have uploaded a couple of charts which are just very basic concepts of joint type and possible adhesives but this is a subject that cant be covered in a simple blog

Painting over epoxy
I have used several Halfords Aerosol spray cans on boats over the recent years.
In each case I have sanded the hull down to bare wood as the boats were vintage ones and did have coats of paint on them that could not be identified.
Best to use thin applications of both primer then paint then build up on that after leaving 24 hours between each coat.
Another good point is that Halfords also stock plastic primer in their paints range which is ideal if your boat has a poly
styrene
hull or you have plastic fittings.

Rudder location, blocking, fabrication
Looking at the proper rudder location, I added some 1/4 triangular hardwood blocking to both sides of the centerboard. Needed blocking to drill through. Was able to pickup the work board and all fit under my drill press to keep the hole plumb. Rudder post will be a 1/4 brass rod with brass tube as a bushing. See photo, brass tube in hull.
Next, I built a rudder substructure assembly which will be covered later with a wood or
styrene
full size rudder to fit the era. Took some very thin brass and formed it around the post, some brass plate and soldered as seen in photos. Brass heats up and solders well using my soldering station.

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 โstandardโ 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.

LED Nav. Lighting
Two days ago I put what I hope is the final paint on the hull, hatch and misc. parts. I like to let it sit for several days to cure, especially in cooler weather.
I took the time to work out LED navigational lighting for my Brooklyn Tug and got that installed. I will photograph that tug later. Back to the springer tug, I had difficulty finding a good mounting spot for the starboard and port lighting so I decided to raise it on a light bar. Photos show the
styrene
structure in progress which will have the green and red side lights and a single white light on the top center post. Worked out the resistor values to reduce current and work off of my 6 volt supply, then soldered as shown. Fed the assembled LEDs through the plastic rectangular tunnel I created. The one photo I took with the red LED turned on is so bright that the camera just picked up a bright spot. I may have to reduce brightness but will test out in daylight first....
These LEDs are very bright and are 360 degree view! Ordered from "superbrigntleds.com" in order to get the full 360 as the ones at the local store were very limited to 18 to 60 degrees. Ordered red, green and white and they arrivedin about four days, great service. I have used this company several times and am happy with them, good to know. More to come, Joe

Ships-Ladder
Back at it this afternoon, handrails are very solid after overnight cure. Trimmed the rail ends to the necessary length. Glued in place. Built a ships ladder, first time for this, think it will work. Need to get ships ladder set to finalize railing.
Ladder railing is seen in photo, I make bends like on this by applying heat and bending with my fingers.
styrene
gets very flexible with heat, but can quickly melt if not careful. I learned not to use my heat gun (used for shrink tubing in my electronics) as it quickly gets out of control. I usually boil water, let it sit and dip the plastic in and out. Easy way to control bends. Joe

Railings
Last night I had done a quick railing mockup as seen in the first three photos. Decided to go with
styrene
and use a rectangular stanchions (verticals) and top handrail along with horizontal round intermediates. Drilled holes through the verticals and inserted the round rods, then glued. Worked pretty well.
Next few shots show how I typically sketch up to scale and determine proper spacers, dividers come in handy for this. Then drew some guide lines for assembly, taped it to my tack surface, covered in wax paper and pinned the assemble in place. Pins do not penetrate anything,just uses pressure to secure. Some drops of
styrene
cement and the parts are welded together. Then on to all the railings needed. Will let dry overnight and trim ends in place.
FYI -- Tack surface is just a piece of acoutical ceiling tile, I cut down the 2'x4' size to make smaller ones for my tiny workbench use. I learned this pinning method from building balsa airplanes, comes in handy a lot...... Joe

Hello, I was not happy with the pilot house and substructure location toward the rear of the tug, that was when I was considering a tug ferry. Repositioned now to the more traditional tug front location. Cut up the old structure and am reworking it. Photos show the progress from last night and today, very time consuming, but I enjoy working with
styrene

Hatch & Tow Bitts
Last night I started on the large hatch that will cover the entire deck opening rather than several hatches, this is to keep with simple approach. The pilot house and whatever else I decide to add will be attached to this for easy removal and access for battery charging and maintenance. it's not as easy as a flat deck hatch as I curved the deck and wanted to curve the hatch as well. See photos, I cut curved sides, then I clamped it to blocks on the bench to bend , glued and let dry for 24 hours.
While that's setting up I started on building some tow bitts. These I am making from
styrene
that I had from my railroad scratch building. See two small for aft and 1 larger at the bow that is in progress.
In addition, I showed some shots of my Brooklyn Tug Bitts. These are heavy duty and were made of brass!
Still enjoying this simple build..... Joe

Deck, servo mount
Put together a pilot house based on some tugs I've seen. Just freelanced it as I went. I build a lot with
styrene
so I am used to just cutting and building. I use liquid
styrene
cement that fuses the materials together. See photo, will trim it out as I mount it, need to add some detail at roof and some Navigational lighting.
Put on on 3mm plywood deck, same as hull bottom. The deck is also curved (proper term is SHEAR) and I started to build up some wood edge at the opening. Will sand everything well, then start sealing and priming all surfaces.
Made a bracket for the rudder servo mount and an adjacent platform for the ESC and RX.
Ordered two 6v 5ah SLA batteries. I will wire in parallel to stay with 6v and get 10ah. I like to stay with 6 volts as I want the motor to run slow like a tug should. Will wire in an in-line fuse. Haven't decided where I will put switch, up high somewhere to avoid water. I will show the wiring once I get to it.
This build is going fast because it's a simple design, just what I was looking for. I work on it late afternoons and into the evening while I watch basketball games. About 4 hrs a day.
Looking forward to building the hatch and getting some primer started tomorrow.

HMS BRAVE BORDERER
After completing the cowl, turned to the rear structure covering the gas turbine and other engine spaces. This can readily be made from
styrene
sheet. The sides and top were cut out, reinforced with โLโ shaped angle and fitted together with CA glue. No particular challenges, other than determining where the various section transitions occur. Luckily had two different sets of plans to compare, so the nuances could be established.
It was not until the rear structure was fitted into the cowl, the assembly fitted to the removable deck and placed on the hull, realized just how important this milestone was. Once everything is firmly located the accuracy of build becomes readily apparent. Any inaccuracies show up as an obvious misalignment.
Was able to check the alignments and squareness using eye, rules, squares and a spirit level and was pleased with the outcome. A subtle sanding of about .020โ off the base of one side of the superstructure and everything became square, parallel and correctly aligned. Quite a relief!
Have always stressed the importance of accuracy throughout a build. This supported that recommendation.
Once the superstructure was completed realized my plan to lift the deck off to gain access to the electrical control switches was impractical. Have thus cut a small access hole in the rear deck to facilitate access. Still undecided how to best disguise the hole, but at least access is now relatively easy.
From now on, until the test program can be continued on the water, will add detail to the model. Doubt there will be much to describe is that of interest, or that has not been covered by others.
Will continue this blog once there is anything significant to report.
In the meantime, best wishes for Christmas and 2019,

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.

Old outboard motor...
Hi Doug, I do have a Hobbyking CNC ally one and now have a brushless inrunner for it. I got it when they were very cheap a while back. Wouldn't pay what they now want for them and Graupner are always way overpriced.
I could be tempted with 7 quid for a Hobbies one though, just to see how it goes together.
The K&O are gorgeous but collector money and the Alterscale are dummies, albeit nice dummies and also bloody expensive.
I sliced the little vintage jobby I bought down the joint line with a fine saw blade in the minidrill today and all is well. it just needs new wires and some grease when I can find some good
styrene
/nylon grease. The motor is a two magnet Kako, many examples of which I have in store. Even has a nice little built in switch. I reckon 3 volts is probably all the transmission can take. The gears are not, as I assumed bevels, but 2 spur gears! I now have to find a way of making the prop shaft stay on the motor shaft!
I'm loving this restoration stuff. Painted the red on my Star yacht today with my best chisel headed sable and got a special 1/4 litre of the emerald green mixed in HMG enamel (the very best there is).
Tried to win a lovely Starlet off ebay, but some sod beat me to it last minute. I hope it leaks

Where gloves are concerned, use blue nitrile as there are probably more people allergic to latex than

Don't know about you though, but I can't breathe in any mask worth it salt. I just do it all outside in the almost permanent breeze that blows round my bungalow. I stand in the doorway of the shed and spray out into the great blue yonder.
styrene
, fortunately doesn't affect me. When Slater's first popularised Plastikard, old man Slater used to demonstrate the making of things like model house window frames with Micro strip and Slater's own solvent called Mek-Pak. The smell was glorious and just oozed quality modelmaking to me. I always made a bee-line to Slater's stand at any suitable exhibition. These days I use Plastic Weld as it does more plastics than just
styrene
and it doesn't have that lovely "esterish" smell.

Since
styrene
itself is an oil, suspected in some countries of being carcinogenic, used in producing various polyxxx plastics, I strongly suspect the the glue is the source of the problem as you can't be coming into contact with

Certainly not melting and I'm pretty sure it was soft solder only as I know he had no knowledge of silver soldering.
I use silver solder (hard soldering) all the time and have done for over 50 years, most of it with cadmium rich (still, I get it from ebay) and I have had no unpleasant reactions. OK, currently I have the shed door open as it's a very small shed, but I never used to in a 7x5. Before that the space was always bigger. Cadmium free modern silver solder is crap as it will not flow as well as Cadmium containing.

I feel like a dunce for not noticing that anchor before. it sticks out like a sore thumb if you know where to look. Thatโs another thing that Iโm surprised hobby engine didnโt add to the boat. I guess in the long run it was easier for moldmaking purposes to omit that particular detail. Thatโs another thing, however, that wouldnโt be all that hard to scratchbuild. All thatโs needed is to cut an opening in the bulwark & build a sheet

box for the housing. itโs not exactly a high priority item, but I think it would go a long way toward adding realism.
So far none of the photos of the Wyforce I seen show what the anchor enclosure looks like on the inside of the bulwark. Then again maybe some of them did & I missed that, too. I assume thereโs an anchor winch, possibly below deck near the chain locker. I expect thereโs a โdrop/raiseโ button inside the pilot house. Iโll browse for a photo of the anchor & post it if I succeed.

LED Tug Mast Navigation Lights
Hello, Doug:
I stumbled upon some other LEDs that are particularly well suited for navigation lights. They have the same specs as the rectangular LEDs shown in the photo I posted recently, but what makes them ideal for me is that theyโre flat-topped, not domed. Theyโre cylindrical in shape, still 3mm diameter & look quite similar to shipโs lanterns (see photo). With your experience youโve probably seen these before, but I was surprised to see them. My plan is similar to the original idea for making scale lights, except as we last discussed white LEDs will be used everywhere, colored by dipping them in appropriately colored glass paint. For the mast lights that will remain white but need to emit light at a given angle, Iโll mask & paint the LEDโs body the same color as the mast, resulting in a clear aperture. 4mm & 2.5mm diameter disks punched from sheet
styrene
, glued one atop the other, then painted & glued to the top of each LED will form the lightโs top covers.
What do you think?
BTW, the flat-top LEDs are also available in a variety of colors. if anyone is interested Iโll post the url to their location.
