  1. No progress over the past week. I've been busy finishing some other projects for an "RAF 100" event at the local aircraft museum. I also spent a day removing and rebuilding my Jeep starter motor - a job more fiddly than scratch building in 1/700th scale!! I hope to get back to 'Bruce' shortly.
  2. At the back end of last year, I was contacted by a friend who was interested in a couple of Broussard models. After a quick search, I found there were no current Broussard kits available and because he wanted a couple of models, the most logical option was to scratch build a master model, then moulds and resin cast parts. After a chance viewing of a thread here on BM, I found out that there were other people who might be interested in the Broussard too. I guess they'll have to wait and see how this turns out!!! It's quite some time since I scratch built something at this size. I'm more used to scratch building between 1/6 and 1/3 scales! I've just finished a project, and another is nearing completion, so I'm just about in a position to start working on "Bruce", the affectionate name for the Real Aeroplane Company Broussard that I'm using as reference. I have some drawings and photos of the aircraft, but I'm planning a research trip to the aircraft in two weeks time for further measurements and photographs. I should be in a position to make a start on the master parts soon after that visit. The model will be about 7.5 inches wingspan and about 4.7 inches long. Here's a few pictures of the subject aircraft that I was lucky enough to have a flight in last year. @RidgeRunner @Wez @stevehnz @Colin1967 @fightersweep
  3. Most memorable film scenes..

  4. Revell (Matchbox) Hawker Fury Mk.I 1/72

    You could be right.......... Still a beautiful job on the model and detailing.
  5. Imperial War Museum LondonĀ“s Fw 190A-8

    I've no other information other than the two photos posted. The 190 was most likely captured or recovered at the end of the war, and was probably used in RAF/USAAF evaluation, so I expect it would have had an Allied markings repaint during or just after the war. At some point after that, it was probably returned to German markings for display. All speculation of course, I don't know the history of the airframe.
  6. Imperial War Museum LondonĀ“s Fw 190A-8

    I'm pretty sure this is the same aircraft, seen at Duxford in the 1980's before restoration. I think The Fighter Collection did the work. It's shown below at the back of the hangar, and appears to have been repainted in this picture. Since the Spitfire is in "Piece of Cake" colours, I'm guessing this picture was taken around 1988/89.

  13. On the trail of the Lone Pine Club

    It's been 11 years since my last layout for myself. I'll sit in on this. All my layouts have had aircraft on them somewhere, from a single aircraft as part of a war memorial, to the huge scrap yard at Kingman Arizona! Even a 009 layout set in World War 1 with a Royal Flying Corps airfield.
  14. Yet another 2 Vulcan B2.. XM571 XH537

    Pleased the painting tip sorted your masking creep!
  15. Can you tell what it is yet? I'm pretty pleased with the progress so far. It's not been particularly difficult so far, just tricky working with quite small parts and sub-millimetre tolerances. The cabin roof will need sanding for the centre wing section. I'll probably make the centre section as a seeparate part, rather than it being part of the cabin casting. So that and the tail cone next and that will be the basic fuselage structure done!
  16. Once the windscreen was sanded, a small piece was cut for the section between the firewall and the start of the screen. This was cyanoed to the brass template to hold it still and it was then sanded to match the firewall. The horizontal break line between the upper and lower cabin area was then covered in Sellotape as a glue barrier, the spacer and main cabin fitted together and a little thin cyano run into the joint to glue them together. This now just needs a little filling and sanding for the fairing that blends the fuselage into the screen.
  17. The new block was cut along the horizontal separation line and the lower piece glued to the main cabin section. The firewall brass template was then screwed to the front and this lower part sanded. This includes a slight taper inwards towards the firewall. The upper part of this block was rough cut for the windscreen angle. The windscreen section was then glued to the main cabin window section ready for shaping. In order to get the fuselage shape right ahead of the glazing, the cabin piece was attached up against the firewall for sanding. A spacer at the back kept it against the firewall and it was screwed through the brass templates from both ends.
  18. Cabin section today! While the firewall former is slightly narrower than the main cabin, it was attached to the front of the cabin block as a guide to the shape and size. The upper and lower edges were cut and sanded first. The sides were sanded next, running parallel forwards towards the firewall template. After sanding the upper and lower curves the brass templates were removed. Because of the saw cuts and sanding the ends smooth reducing the overall length of the front block, a new piece was cut for the cockpit window section up to the firewall.
  19. All too soon, it was school pickup time again and that was it for another day. Progress seemed slow early on in the day, and while I didn't have any targets for the day, I was pleased with the results so far.
  20. Next came rounding off the corners. It's a bit tricky as the fuselage isn't a straight taper. The sides and underside behind the cabin, have a slight curve in so the brass templates had to be used as a guide for each end, blending the shapes where the taper changes. Overall, it worked well. The third brass former made is for the firewall. The former from the front of the rear fuselage, will be reused on the back of the front fuselage block, with possibly one more former at the wing spar position through the cabin. The styrene templates made first, were used to score the outline of the former onto the 0.45mm thick brass sheet.
  21. The resin was cut roughly to shape on the bandsaw, leaving around 1mm to 2mm of excess beyond the brass templates. After a rough sand on the belt sander until close to the templates, the rest was finished off with 240grit wet and dry attached to a flat acrylic block as a sanding tool. The side and plan profiles were sanded first, wet sanding the resin block down to the edges of the brass.
  22. In order to make the fuselage sanding a little easier, I decided to make some brass formers as sanding templates to attach to the resin block. Sub-millimetre accuracy in cutting was important, and so the excess was ground away with a rotary grinding stone while peering through a x15 watchmakers magnifier. The first two brass formers were for the rear fuselage taper and it worked surprisingly well. They were tack-glued to the resin, carefully lining up the centre lines scratched onto the formers with those in the resin block. They were then drilled and screwed in place to hold them securely during sanding.
  23. The cabin part had nice easy exterior faces to sand on a flat bench with some wet and dry paper stuck down. The fuselage part of the cut was more tricky to sand smooth and square, but I had an easy fix for that, brought from my days building large, multi-section R/C aircraft. After the cabin piece was nice and smooth, I gave it several coats of mould release wax along the mating faces. After that, out came the tin of P38 car body filler. A dollop was mixed up with the hardener and spread over the fuselage mating faces. Before it cured, the two parts were joined back together again with some M3 studding and the bolts tightened up, squeezing out excess filler. After it cured, the studding was removed and the two parts popped apart, leaving a perfect joint. The cabin section can now be bolted securely in place for fuselage shaping and once sanded to section and glazing sorted etc., the two holes in the top of the cabin and bottom of the fuselage can be filled and sanded flush. Once the silicone mould is made, I intend to pour the resin fuselages through the firewall end, so the sloped face at the rear of the cabin is to aid air bubble escape from the rear fuselage part of the moulding. That was it for today. Not too bad for only a couple of hours of available time.
  24. Having sanded a slight taper on the section just ahead of the tailplane, I realised how difficult it was going to be to create a symmetrical fuselage which also changes section shape, just by offering up the templates against the resin block. I'm now considering cutting the fuselage black at the tailplane former, and making a complete male template that can be glued to the block at this tailplane position. I may even make it from aluminium or brass as a sanding guide a little tougher than the resin itself. I may do the same behind the wing and at the firewall position, using these styrene templates in addition to the template attached to the fuselage blank. I little more experimenting needed I think. I want to mould the glazing/cabin section from clear resin. A hollow, detailed cockpit isn't a requirement for my primary customer ( a rework may come at some point in the future, but right now it isn't a concern ). As a result, that part will need to be moulded separately, but I need the shape to flow with the rest of the fuselage. It would be best shaped with the main block. I would then separate it, reduce its width by about 0.5mm each side, and add 0.5mm styrene window frames. The first step was to drill the cabin section with two 3mm holes vertically through the block. I then used the bandsaw to cut the cabing section off. That of course left harsh bandsaw blade cuts into the resin.
  25. After my meeting this morning, I didn't get back to my workshop until 1pm. With little legs being chucked out of school at 3:15pm, it didn't give me long to get much done. I did however make some progress. I started with some small scraps of model board and sanded them to match three of the fuselage templates. It's a tricky job sanding to such small tolerances and the experience pointed the way for tackling the fuselage. As the three sections were sanded, they were compared to the photographs of the real aircraft to see how the shaped compared. Overall, they seemed to work out well but of course sanding a fuselage that changes from a very rectangular section to more of an elipse with flattened sides, top and bottom was going to be challenging. I can see a jig coming soon that the fuselage blank can be slotted into to check overall widths and tapers before the shaping commences.
