That's how they get warped in the first place . One side gets damp and expands while the other stays dry . Try it and see what happens even without the weight after . So... Steaming improved things a bit but still had a bit of a warp. I next tried wetting the concave side but that has made things worse. I have some ammonia knocking around, that I have used for tight bends in balsa before, I might try using that. Failing that, I will cut a new part. 1 Quote Link to comment Share on other sites More sharing options...

I’ve had the same thing on a couple of models so I just cut a slot through the balsa, across the grain, then glued a lolly stick in the slot whilst keeping the balsa flat. Worked a treat plus I got a lolly to eat. I would advise against Magnums as their sticks aren’t straight and can have facial hair. Quote Link to comment Share on other sites More sharing options...

Geoff Gardiner Posted April 12 Author Share Posted April 12 I hate to admit defeat, so I am giving Ron's lolly stick idea a go 🤞 1 Quote Link to comment Share on other sites More sharing options...
Ron Gray Posted April 12 Share Posted April 12 Ah, you should really put them in on edge not flat! Like this: 1 Quote Link to comment Share on other sites More sharing options...
Geoff Gardiner Posted April 12 Author Share Posted April 12 Ah yes, obvious now I think about it! Every day's a school day. Quote Link to comment Share on other sites More sharing options...
RICHARD WILLS Posted April 14 Share Posted April 14 Wood eh ? Funny old stuff . You can get Magnums in a three pack for £3.15 . You've used two , so raised the value of the P51 by £2.10 Ive used individual Tiramisu pots for wheel well lining before and it works out more like £2 each . Conversely , you can nip into McDonalds and get coffee stirrers for nothing and those little paper cups that you put the sauce in (which I have yet to discover a use for ). Is this going to be a new kind of modelling Ron ? A bit like Kevin Costner using ski boots to walk on the sea bed in Water world ? Maybe we could make a man carrying model with stuff from the recycling bin ? 1 Quote Link to comment Share on other sites More sharing options...
GrumpyGnome Posted April 15 Share Posted April 15 I have a shoe box pretty much full of coffee stirrer sticks. Neither my wife nor I take sugar but replenish my stock each time we visit a coffee shop from one of the large chains...... They used to be used extensively to reinforce and repair foamies, now mainly as epoxy stirrers, so stock levels are high. Somehow, I've managed to accumulate quite a number of pieces of carbon in various sizes to use as reinforcement...... probably salvaged from dead models as I don't recall ever buying any. 2 Quote Link to comment Share on other sites More sharing options...
leccyflyer Posted April 15 Share Posted April 15 Yep, every time I buy a cup of overpriced brown liquid from one of those chains I collect an appropriate number of these very useful stirring sticks, despite taking neither sugar, nor milk. They are so useful in many ways - perfect leading edge reinforcement for 6mm depron wings, superb paint and epoxy stirrers and applicators and clipping the end off makes for nice lightweight control horns. The chain doesn't lose out, since I'm partaking of neither sugar, nor milk and they would go in the bin anyway. I've nowhere near a shoebox full though, maybe a dozen on the go at any one time. Don't eat Magnums these days but a bulk buy of lolly sticks from eBay is very cheap, with hundreds in a pack and lasts a long time. These are useful as stirrers and applicators, plus local hardwood reinforcement - nice hardpoints for mini and micro servos into balsa and foam.

Geoff Gardiner Posted April 15 Author Share Posted April 15 Do you think I would get 'rumbled' if I got some coffee stirrers as I don't take milk or sugar - nor drink coffee? 1 Quote Link to comment Share on other sites More sharing options...
leccyflyer Posted April 15 Share Posted April 15 £3.49 for 200 on eBay - that's less than tuppence each. Quote Link to comment Share on other sites More sharing options...

Geoff Gardiner Posted Sunday at 21:09 Author Share Posted Sunday at 21:09 This is my take on fitting the radiator on the underside of the wing. first I added some extra width to the base that gets glued to the wing. Instead of sanding a V shape on the underside to fit the dihedral, I cut it in half and sanded the top flat. Then I added some extra width to the radiator and sanded to shape. Here I really struggled to get the angles right to blend with the vac formed front scope - it just didn't look right. So I tried gluing on some scrap balsa and sanding to shape. I think I will go with this option. More later... 7 Quote Link to comment Share on other sites More sharing options...
Geoff Gardiner Posted Wednesday at 13:34 Author Share Posted Wednesday at 13:34 A bit of filling and sanding of the wing today. It's getting closer to being finished! More later... 2 Quote Link to comment Share on other sites More sharing options...
