TommyP Posted November 18, 2014 Share Posted November 18, 2014 In a moment of sheer madness over the weekend I dug this out of the stash and thought to myself 'it can't be that bad, can it?' Combat Models are notorious for being, well, hard combat to to build, but I don't get on with resin and I like a challenge so here goes... The 'kit' is rather basic and the plastic is just a little thicker than fag-paper. It's also covered in ripples, bumps, throughs and dips so the surface will need a lot of preparation. Panel detail is non-existent, but should be fairly straightforward to add. Here's the fuselage: The first problem I encountered (it didn't take long) was the fact that the left wing-root is further forward than the right: There also appears to be another major problem with the fuselage, as when I compared the scaled up measurements to the Revell 1/144th scale kit, the wings are an inch too far forward on the Combat kit, so the whole wing root area needs moving back. First job was to cut the wing root out completely: An inch was removed from the rear of this section: The fuselage was lined with card at the join, and the wing root reattached an inch further aft: The piece removed earlier was then reinstated to plug the gap, and now the wing sits in the correct position (see the unaltered fuselage half above): With the plastic being so thin, a vast amount of reinforcement is need for the interior so the kit can support itself and the weight of the wings etc. This has all been added with plastic card bulkheads: I now have something starting to resemble a C-17 fuselage... ...but there's going to be a long journey ahead.

Kurt H. Posted November 19, 2014 Share Posted November 19, 2014 If you have time, could you describe your process for making the bulkheads? what did you use to measure the inside of the fuselage, and what is your process for cutting the plastic? I can never seem to cut styrene that cleanly. Quote Link to post Share on other sites
TommyP Posted November 23, 2014 Author Share Posted November 23, 2014 Kurt - there's no real secret to making the bulkheads. The fuselage is roughly circular so it was just a case of measuring the diameter and using a circular cutter to make plastic card bulkheads to the correct size. Lots of test fitting, sanding, re-testfitting, sanding etc and when at the correct size they are simply stuck into place. There's been some good progress this week on the C-17 - it's taking a while but I did expect that when I started this project! I've joined the fuselage halves which was quite a challenge. The bulkheads have worked well and kept everything nice and rigid, but as you can see from the picture below the fuselage halves are different lengths. I used the wing centre-section as my point of alignment as keeping the wings level is a must - however the tailcone will need some serious work; the fuselage parts are not only different lengths but completely different shapes: The profile of the nose and cockpit areas are also well off when compared to the Revell 1/144th kit, so I removed the cockpit area and fuselage crown, reprofiled it and then reattached it. I'm hoping the remaining shape issues will be remedied by a good session with some filler: It now has the distinctive narrowing towards the front end, rather than being too bulbous as the original profile was: When I'm happy with the fuselage shape I will once again remove the flightdeck area from the model and work on scratch-building the cockpit interior. When completed, the flightdeck roof can be reattached. I've now applied liberal amounts of automotive filler to the model, which will help greatly the reprofiling of the nose and repositioned wing roots: Looks like I'll be settling in for a session or two with the wet and dry...

TommyP Posted November 24, 2014 Author Share Posted November 24, 2014 Wow. I think you made that look way easier than it really was. It's really not that difficult - just a case of patience and perseverance... in that order! A good session with the sandpaper this evening... the repositioned wing-root and reprofiled nose has blended in well. A few patches of filler have covered some blemishes: The mis-shapen tail cone has almost been beaten into submission: Undercarriage sponsons... hmmmm... should be interesting: Tom Quote Link to post Share on other sites

TommyP Posted November 26, 2014 Author Share Posted November 26, 2014 A little more progress for you this evening... I've cut the sponsons out of the backing sheet and sanded them to shape, as well as removing the undercarriage door in preparation for scratch-building the wheel bays: The fit to the fuselage itself is remarkably good - all that was needed was a little careful trimming and sanding. These shots show them taped roughly into position - more exact measurements will be needed when it comes to attaching them properly: It certainly looks more C-17-like with the sponsons in place.

Aurora Mark Posted November 27, 2014 Share Posted November 27, 2014 Brilliant work! I do have to say I like the work inside the fuselage. I'm staring at my CP-140 (still on the sheets), and was contemplating using expanding foam in areas that wouldn't be seen, but I really must say that your approach is nice, neat, and I'm sure saving the landing gear a lot of weight to deal with later on. What type of filler primer do you use? Thanks Quote Link to post Share on other sites

What type of filler primer do you use? Thanks I'm always nervous about using foam - I've seen horror stories of it getting hot, melting the plastic, over-exapanding and generally making a right mess! I stick to what I know and that's plastic card bulkheads. Nice and strong, as well as being light. The filler-primer is automotive paint. Here in the UK it's from Halfords, but I imagine most automotive paint brands have something similar. It goes on in nice thick layers, and once dry (about 30mins) sands beautifully to fill any surface imperfections. The plastic on this kit is quite rough and it'll need a few applications by the look of it. Tom Quote Link to post Share on other sites
TommyP Posted November 29, 2014 Author Share Posted November 29, 2014 The C-17 has had two more coats of filler primer today, with a light sanding in between and the fuselage is finally at a stage where I'm happy with it. The primer has covered the multiple dimples and ridges and has left me a lovely smooth surface ready for scribing and adding surface detail when the time comes. The repositioned wing root area and reprofiled cockpit area have blended in beautifully and it's now impossible to tell that they've been moved and modified at all: Some general shots of the fuselage: Tools of the trade for today's session: And it's always important to have a willing assistant: meet Alfred! Work can now continue on the sponsons and undercarriage bays. Until next time, Tom Quote Link to post Share on other sites

Thanks Major... glad to know I'm inspiring someone! Evening all :)/> I've been working on getting the undercarriage sponsons attached to the fuselage over the last few sessions. After working out exactly where they're positioned (using Revell's 1/144th scale kit) work began by adding some basic detail to the fuselage sides which form part of the wheels bays: The sponsons themselves had some structural detail added to box in the bays, add the small intakes on the front edges made from plastic card and the APU exhaust added to the right side. The small doors on the outer sides were opened up, too: Once this was complete, they were given a final trimming and sanding and added to the fuselage sides. A quick lick of filler and they were on: Next up is the fin... Until next time, Tom Quote Link to post Share on other sites

I started a Shack from Sanger in 1/48th and when I see your job, I want to put mine in the trash For the sponsons, did you know that the C-17 have one longer then the other ? (the right if I remember correctly) After moving the wing root, it'll not be a difficult task for you Damien Quote Link to post Share on other sites

Was great fun! I'm glad to hear there's another madman out there! You're absolutely right about the starboard sponson. The Combat kit does have it longer, although I'm not convinced it's quite long enough when compared to the Revell kit. I may or may not do something about it - it may be more hassle than it's worth.

Joel_W Posted December 4, 2014 Share Posted December 4, 2014 Tommy, I just read through your entire build to date, and I'm speechless. Your work is incrediable. The higher one's skill level, the easier he makes the work seem. I've been modeling for a long time to know just how difficult it really is to do what you're doing.
