Iain Posted March 7, 2023 Author Share Posted March 7, 2023 Nose section is getting there! From this: To this: Still some finessing of high points/curve blends - but these are to be expected. More when there's more... Iain KiwiZac, MikeMaben, Trak-Tor and 13 others 16 Link to comment Share on other sites More sharing options...
Palm-tree Posted March 7, 2023 Share Posted March 7, 2023 That looks really precise after the cleanup, this is going to look amazing when it is finished. Iain 1 Link to comment Share on other sites More sharing options...
Iain Posted March 12, 2023 Author Share Posted March 12, 2023 A little more progress on the shaping - slow, but really rewarding! There'll be another coat of grey, followed by some high-build yellow filler primer to follow - but these show where the 'cheeks' have been sanded through the outer print layer - and the area subsequently filled with polyurethane casting resin: Hopefully make a start on the rear 'capping spars' for the wings this evening.

Iain Posted March 20, 2023 Author Share Posted March 20, 2023 More finessing on the nose section - now with a few layers of Filler Primer applied for final shaping. A few blemishes filled with Revell Plasto filler. These parts spend their life in the warm airing cupboard when not being worked on - to ensure that every layer of primer and filler is properly dried off at each stage. As the nose is a very obvious/most looked at section of any model it's important it's as good as I can get it. Back in a mo...

Iain Posted March 20, 2023 Author Share Posted March 20, 2023 Now - back to those wings... Earlier on I'd posted images of the assembled wings - minus the removed flap areas. The flap areas need boxing in - both for neatness - and for strength. I wanted to get these boxed in before smoothing and truing up the wings. Photo below shows the Starboard wing (upper in photo) with new styrene sheet sections added - and Port wing (lower) withe the edges trimmed back to the wing surface/rear edge after allowing the Plastic Weld to dry off for 24 hrs. Vertical section is about 0.5mm thick - horizontal is 1.5mm - wing now a lot stiffer - and straight along the rear edge. Flaps will need to be drawn up in CAD and printed on my 4K resin printer - and will be fitted in the fully up position - so no detail needed inside the flap area. Easier to cut sheet over-size and trim back - note that rear edge is not the trailing edge - that will be formed by the flap sections when eventually fitted. Below is the Port wing - which has had everything trimmed back and a start made on sanding everything flush along the wing surface - in this case using 60 grit Glass Paper on a flat surface - a la vacform... Hopefully get some of the 'low' areas on the wings filled and sanded later in the week. Model on dudes!

Iain Posted March 23, 2023 Author Share Posted March 23, 2023 The nose section is getting there - but still some areas to sand back/re-profile. I've marked the areas to be reduced with the letter 'x' - and a dot where I need to add a little to the nose to make it just slightly sharper. This is after a lot of pouring over photos and comparing with the printed parts. I think it will still be a little 'jowly' in plan view - but I don't think it'll be *that* noticeable on the finished model. If I can get these tweaks done by the weekend I can do some surface detailing of this area - and make a start on the interior... I might even get some filler primer on the wings. Really enjoying this - and the strength of the printed parts makes things so much easier than a vac! Have fun...

Ryan Posted March 23, 2023 Share Posted March 23, 2023 @Iain What a job, that PLA is crap to sand....wonderful results! Ryan Iain 1 Link to comment Share on other sites More sharing options...
Iain Posted March 23, 2023 Author Share Posted March 23, 2023 Thanks Ryan - this is printed in ABS - so a lot stronger than PLA - in fact, I wouldn't want to touch anything that's printed in PLA... HIPS is my preferred, but One Man Model prints using ABS (although I see he's now doing some parts in PETG as well as resin?). ABS doesn't sand easily - but I've found a 60 grit glass paper cuts through nicely - and the primers I'm using do their job well! Whilst I know many would be put off this kind of project due to the presence of the layer lines, IMHO, they're really not that difficult to sort, and there are more challenging aspects to the build than surface prep!

Ryan Posted March 23, 2023 Share Posted March 23, 2023 Will you be scribing into the primer for panel lines? @Iain I haven't worked with ABS yet, thanks for the info. Iain 1 Link to comment Share on other sites More sharing options...
Iain Posted March 23, 2023 Author Share Posted March 23, 2023 Some panels will be scribed - and some masked and a line of filler primer applied to simulate overlapping panels on the real airframe. Where I'm scribing into the surface I try to ensure the layer of filler-primer is thick enough to allow for the scribing - rather than going into the ABS and the possibility of uneven lines. That's the theory, anyway... I'm currently stressing over what to do about the myriad of tiny dome-head rivets - but I'll work that one out later in the build.

scvrobeson Posted March 23, 2023 Share Posted March 23, 2023 There's the orange primer. Wouldn't be one of your builds without it. Great to see the attention to detail that you're showing to make sure everything is correct. looking forward to what's next. Matt Iain 1 Link to comment Share on other sites More sharing options...
Iain Posted March 23, 2023 Author Share Posted March 23, 2023 That orange filler-primer has got me out of - and probably into - a lot of trouble over the years. It's *really* useful stuff Matt - just don't apply it to one side of thin plastic parts - it shrinks as it dries - and can badly warp things. Don't ask how I know - but it *might* involve a Dragon P-51D, and filling rivets, and a bin. Iain scvrobeson, ctayfor and LSP_Kevin 3 Link to comment Share on other sites More sharing options...

Iain Posted March 24, 2023 Author Share Posted March 24, 2023 Cheers buddy - but make it "if finished" - I don't have the best track record at actually finishing things these days... Do appear to be on a bit of a roll though at the moment - and enthusiasm high. Iain LSP_Kevin and ctayfor 2 Link to comment Share on other sites More sharing options...
ctayfor Posted March 24, 2023 Share Posted March 24, 2023 I have just caught up on this thread and I find it fascinating for several reasons. Firstly because my Dad flew HS748s for Polynesian Airlines in Samoa in the early '70s; secondly, because I enjoyed flying in the jumpseat several times, thirdly, because I worked part-time for Mount Cook Airlines while I was at University and their main airliner was the 748 then, and fourthly, because I strongly admire your approach to the subject. Your attention to detail and authenticity is stubborn in the most positive way, your skills are well-established, but you are unafraid to expand them and to learn new tools and techniques as you go. You treat learning curves as adventures rather than as barriers. I look forward to this particular adventure reaching a successful culmination.
