Iain Ogilvie Posted April 11, 2015 Author Share Posted April 11, 2015 Will be at Cosford - but nothing available just yet - next step is to get a pressure chamber. Iain Link to comment Share on other sites More sharing options...
tonyot Posted April 11, 2015 Share Posted April 11, 2015 Great stuff Ian, I`m interested in a set too but it depends on the price really. Great work you`ve done by the way,.......you have really pushed your envelope to achieve great things, Cheers Tony Link to comment Share on other sites More sharing options...
Iain Ogilvie Posted April 13, 2015 Author Share Posted April 13, 2015 Thanks Tony - I've certainly learned an awful lot - about the Lightning - pattern making - casting - and my own abilities (or lack thereof!). I think I've found the ideal pressure chamber for de-bubbling the resin - subject to it being large enough internally I'm aiming to collect it tomorrow. And a big thank you to everyone I chatted to at Cosford yesterday about this project - the support/banter/commiserations has given me a bit of a lift. You guys know who you are! More soon - I promise! I too am suitably impressed, Iain, are you attending Cosford with any bits? Great to meet you yesterday mate - and thanks for the support!

Iain Ogilvie Posted April 13, 2015 Author Share Posted April 13, 2015 In breaking news - looks like I've purchased a 12l pressure vessel rated at up to 8 bar (116 PSI!) - 9.5 inch internal diameter - by 12 inches high - should do me for now! Plan is to collect tomorrow Iain 1 Link to comment Share on other sites More sharing options...
general melchett Posted April 13, 2015 Share Posted April 13, 2015 Great to catch up with you and Iain minor again yesterday, good luck with your future plans. The pressure vessel sounds interesting and I look forward to seeing the results...no pressure of course, (OK, well at least 116 psi of it !!).... . 1 Link to comment Share on other sites More sharing options...
Iain Ogilvie Posted April 13, 2015 Author Share Posted April 13, 2015 Great to see you yesterday Melchie - and thanks for the chat - really appreciated... Edit - was mislabeled as 8 bar - actually 6 bar - 90 psi - but more than sufficient! Glamour shot of the chamber: Iain 3 Link to comment Share on other sites More sharing options...
Iain Ogilvie Posted May 4, 2015 Author Share Posted May 4, 2015 Pressure tank collected - air line quick release adapter fitted - tank pressurised to 6 Bar/87 psi and left for half an hour. Happy to report no leaks and the tank gauge and pressure relief valve working perfectly... In mean time I'm working on patterns again this afternoon in the sunshine - will post photos soon. We're getting there - I *think* Oh - and hope you like the logo Iain 2 Link to comment Share on other sites More sharing options...

Ex-FAAWAFU Posted May 4, 2015 Share Posted May 4, 2015 I have absolutely no intention of ever building a 1/32 Lightning... but I am hooked! Great logo, by the way. Link to comment Share on other sites More sharing options...
Max Headroom Posted May 4, 2015 Share Posted May 4, 2015 I like the logo but are the RAF still claiming copyright on the roundel? Good luck in your venture btw Trevor Link to comment Share on other sites More sharing options...
Iain Ogilvie Posted May 4, 2015 Author Share Posted May 4, 2015 'Roundel' isn't the RAF colours - it's black/white/red - so unless the guys at MOD have registered concentric circles in all colours... Got sidetracked into going for family walk down by the river at Lechlade - so photo's to follow next few days. Have done a test cast on the gun ports and in process of making the intake ring mould. Horizontal stabs ready to go into rubber - and late fin almost complete. Canopy draft has tape laid on whilst I work out the correct framing positions. Cockpit sill master now has locating flanges and front spine fitted - and coaming being worked on. F Mk 6 belly pack is having gun troughs added and final shaping.

Radleigh Posted May 4, 2015 Share Posted May 4, 2015 Sounds like it's all coming together at last Iain, can't wait to see a set finished Link to comment Share on other sites More sharing options...
Iain Ogilvie Posted May 11, 2015 Author Share Posted May 11, 2015 Hi all, Promised some photos/update - and nows a good moment before I mix some more rubber Corrected tailplanes - pour stubs added and ready to make two part moulds. Note brass rod - this will leave a 'slot' in the rubber moulds where I'll add more brass rod and embed in the resin - should be strong! Nose intake ring - waiting for first half rubber mould... Cockpit surround - final shaping of spine (now bonded in place). Also new, narrower, coaming panel that fits well - but needs detailing. Area at front of spine will be detailed also. Bottom flanges added to aid fit with fuselage cut out - fits perfectly. Test 'canopy' in place to check sizes/fit and a first play at where the framing goes - more work needed here - canopy pattern needs narrowing a little all round and clear pane 'masks' not right yet.. Basic spine pattern - now correct widths - smooth curves and straight as an arrow! F2A/3/6 fin - corrected shape - front intake added and hollowed out - just adding surface detail. Should be ready for rubber this week. Rear 'cheeks' final shaping complete - adding surface detail: F2A/6 ventral fins - almost ready to cast: First 'test shot' cannon panels - before I had my pressure tank! F Mk 6 ventral tank - nose cannon port castings being 're-purposed' prior to bending in and shaping: Test shot cannon ports in place - first casts quickly removed from pour stubs - not bad for a first go I think! Bit of shrinkage here - modding masters a little to allow - but fit still better than the kit parts - and would have been better if I hadn't butchered the part at rear when removing from pour stub: Sorry it's all been a bit slow - but final quality should be OK! (crosses fingers...) Off to mix rubber Iain 5 Link to comment Share on other sites More sharing options...

Iain Ogilvie Posted May 11, 2015 Author Share Posted May 11, 2015 Just degassing this evenings batch of rubber - amazing how it behaves in a vacuum - and how much air is in there!! I know - old news to you hardened casters out there - but still a thing of wonder to this newbie! Iain Link to comment Share on other sites More sharing options...

Iain Ogilvie Posted May 14, 2015 Author Share Posted May 14, 2015 Bu**er... Looks like the mould release agent I've used isn't up to the job (BondIt Silicone Release Spray - it lives up to first name - not third it would appear!) and my mould halves won't separate.Solid, impenetrable, inseparable. Never had this before with other silicone sprays?No problem for the tailplanes as they will work as single part moulds - and I've easily extracted the patterns. The nose ring mould however - well - that's had to be destroyed in the process of safely removing the pattern.2 steps forward - one back. Question for the experts - what do you recommend?

Mike Posted May 14, 2015 Share Posted May 14, 2015 Tough break with the nose ring, but at least you got it out ok I was recommended Atlas Polymer WAX-1 for rubber to rubber contact, although I've not used mine yet due to the lapsing in my casting aspirations 1 Link to comment Share on other sites More sharing options...

Iain Ogilvie Posted May 17, 2015 Author Share Posted May 17, 2015 I'm now the proud owner of a small tub of vaselene! (Quiet please you lot in the cheap seats...) Just ordered one of RB Productions riveting tools as well.This afternoon we've done a test pour on the tailplanes - first objects in the pressure tank and the first full prototype parts - and they've come out beautifully considering I'm using old tins of resin at the moment for test shot purposes. Chamber worked perfectly - and not one bubble in the castings - at least that I can see. A few small bits of Plasticine from the mpould making process but that's it (that that should all be gone now).Really pleased with first results:And test pour on the broken nose ring mould - front part of ring has come out perfectly but has shown I need to add some subtle rivet detail. Rear end where it meets kit trunking *not* production quality - but new mould will cure that Hopefully more progress next few days.Iain 3 Link to comment Share on other sites More sharing options...
