ClumsyDude Posted October 9, 2017 Share Posted October 9, 2017 I must say, I've felt nervous about Iain hacking the Spitfire fuselage up, so I'm not sure how he's feeling about it! You too eh Dean? Link to comment Share on other sites More sharing options...
DeanKB Posted October 9, 2017 Share Posted October 9, 2017 You too eh Dean? And now we have to wait a couple more weeks!! Ah well, it gives me time to get back to hacking my Ju 88 up and turn it into a Ju 288. At least I have instructions. Link to comment Share on other sites More sharing options...
Iain Posted October 17, 2017 Author Share Posted October 17, 2017 Booked in for some measuring and photos of the real thing next week, something that will enable me to get serious with the major work on this project.

KiwiZac Posted October 17, 2017 Share Posted October 17, 2017 Excellent news Iain, this is a very exciting project and I'm very grateful to your client for allowing you to share progress. You do realise that wartime they didn't have the RR rockers on them, they were cancelled early on and only came back post war, though it probably has them on it these days, the writing was often picked out in red btw. And you do realise that the Grace conversion didn't exist until Nick Grace created it in the late 1980s for his restoration of ML407? Link to comment Share on other sites More sharing options...
Iain Posted October 17, 2017 Author Share Posted October 17, 2017 Just in case anyone gets the impression I'm building a replica of the 'Grace' Spitfire itself; I'm not. This will have a few differences and built to my customer's specification and markings. My reference to the 'Grace' Spit is in relation to the canopy design used on that airframe, which this model will feature Iain Jeff, KiwiZac and MikeC 3 Link to comment Share on other sites More sharing options...
KiwiZac Posted October 18, 2017 Share Posted October 18, 2017 Ah. I was going to ask if you were replicating an existing machine or one based on the client's own wishes. Link to comment Share on other sites More sharing options...
Iain Posted October 23, 2017 Author Share Posted October 23, 2017 Mia culpa Zac - the thread title could be a little misleading! Off to measure up a Spitfire tomorrow - then we can really make progress! Iain KiwiZac 1 Link to comment Share on other sites More sharing options...
RLWP Posted October 23, 2017 Share Posted October 23, 2017 Off to measure up a Spitfire tomorrow You lucky, lucky, lucky b....... Lots of pictures please Richard Shawn M and Jeff 2 Link to comment Share on other sites More sharing options...
Iain Posted October 25, 2017 Author Share Posted October 25, 2017 Not sure I'll be allowed to share the images (I have asked - we'll see) - but very useful visit! I think I now have most of the structural changes/elements covered off in my mind, so should be able to start fuselage work shortly. In the mean-time - if anyone in Europe has an 'abandoned project' Tamiya Spit (Mk VIII, or Mk IX) they'd like to offload please shout - I could do with some spare parts to facilitate pattern making.

Iain Posted October 29, 2017 Author Share Posted October 29, 2017 Couple of useful factory drawings that I'm working from - fuselage skinning/frames and a drawing of the rear panel. These are for the standard TR Mk.IX, so with the large rear canopy - but relative positions of the two cockpits/radio access panel etc.. identical. Back with an update on the plastic in near future... Iain Jeff, TorbenD, MikeC and 2 others 5 Link to comment Share on other sites More sharing options...
Iain Posted November 19, 2017 Author Share Posted November 19, 2017 Hi all, It's been a few weeks - now that Telford is out of the way, and thanks to Carl (BloorwestSiR) for sending me the parts for the later wheel wells from the Mk XVIe, I've been able to make further progress. Wings - main cannon bulges filled with Milliput epoxy putty, followed by casting resin to fill the cannon ports and ejection ports on the lower gun bay doors. These were filled, then sanded on a flat sheet of 800 grit wet and dry before fitting to the wing. The parts that Carl sent me also included the outer machine gun 'plugs' from the 'e' wing and they were used here. The final scheme will feature the red sections to simulate gun positions on the model. The Tamiya wing has quite a complex breakdown of parts to reflect the differing versions available - so took a while to come together. The wing will be slightly different to the Grace Spit in terms of panel detail - the Grace Spitfire has a 'wet' wing with fewer individual skin panels. As mentioned, the wing has been fitted with the 'bulged' upper gear bays to reflect those found on most restored airframes. Back in a mo...

Iain Posted November 19, 2017 Author Share Posted November 19, 2017 Undercarriage - assembled ready for clean-up and paint - but the main gear legs are the standard Mk IX type - now I have the parts for the XVIe with slightly differing angles I'll be replacing them. Tail feathers and alierons also assembled and awaiting a date with the sanding sticks (note stainless steel hinges): More in a moment...

Iain Posted November 19, 2017 Author Share Posted November 19, 2017 The BiG progress has been cutting up the fuselage - £100+ worth of cuts if it all goes wrong! The Supermarine station drawing was copied into CorelDRAW and a pink box drawn to the exact distance on the model fuselage from the front firewall datum point, back along the horizontal datum line to the off vertical empennage joint. Why pink? Because that shows up easily over the background drawing. The factory drawing was then scaled to match this distance at the relevant points. Having done this *all* of the strategic points on the kit fuselage matched the relevant stations on the drawings, which meant I could pretty well trust them for horizontal dimensions - which is what I needed. Just to demonstrate distortion to drawings from copying and re-sizing over time, you can see that it's stretched a little in the vertical plane. Something I could pretty well ignore here... Ignore the parallax on the images below - everything lines up perfectly! Iain Jeff, Greg W, Kagemusha and 1 other 4 Link to comment Share on other sites More sharing options...
Iain Posted November 19, 2017 Author Share Posted November 19, 2017 With the horizontal positions identified and sanity checked it was time to mark out the cut points... The major ones are shown in the following image - I like to keep things simple - so plan was to move sections forward along the horizontal datum - which, somewhat fortuitously, lies on a panel line! Out with a fresh No11a scalpel blade and lots and lots of gentle passes. An old piece of photo-etch frame was used as a guide for the initial vertical cut along the curve: Once these sections were removed, it was time to work back to where the new rear cockpit will be - with it's sills at the higher level: In the photo below I've also cut out the opening for the rear entry door: Iain monthebiff, BloorwestSiR, LSP_Paul and 6 others 9 Link to comment Share on other sites More sharing options...
Iain Posted November 19, 2017 Author Share Posted November 19, 2017 Next a start was made on reducing material from the front tank cover - approx 11mm horizontally. The tank was marked up with some 10mm Tamiya tape - carefully aligned parallel with the front edge. Needing to remove 11mm I figured that by the time I'd made the cuts, using my ancient but highly useful razor saw, and then dressed the surfaces I'd be at the 11mm mark. I wasn't wrong! And an image showing the cut fuselage, with the standard kit version. Hopefully explains the major changes required to the fuselage. The gaps from moving everything forward will be filled using sections of spare entry door that are already the correct curvature, feature the canopy rail to help with alignment and are of the same material as the surrounding plastic. All looking really messy at the moment - but a big psychological line crossed - and we'll soon start to re-assemble everything. In terms of other pieces of the puzzle - the interior structure - it's re-assuring to see that with the sections moved forward, certain interior features line up in the new positions, confirming the cut work so far is pretty well spot on.
