Hi TheOne

I made two half tubes for the fuse, I forgot to take pictures while I was building the Spitfire, but here's some photos of how I did my P-40 the same way. It's so easy I didn't use plans.

I am going to make a quick suggestion. If you are going to use 6mm EPP because that is the rigidity you want then I tend to start with 8mm now and then put an iron over it. First cover the EPP with thick Al foil this doesn't stick as a rule as it cools it will peel off again then run the iron over it until it loses the extra 2mm that gives you a nice smooth surface for your model for the finish to be added to.

Great models like both the Spitfire and the P40

Well, you learn something new everyday.... I've never come across that before, I'm going to give it try. Does it make the EPP stiffer or just smoother?

It makes it smooth and slightly glossy if you get it spot on, and it is no stiffer in fact less stiff than the original thickness but stiffer than the new thickness which is why I start with something a bit thicker than I want to end up with. It also seems to resist getting dirt being caught up in it when landing in fields. Rather than paint I often use artists ink to add colour as it weighs almost nothing and finishs easily and is pretty well permanent.

The foil needs to be thick otherwise it has a habit of wrinkling and you have a smooth piece of EPP with the wrinkles etched in it, but with a bit of practice it does leave it looking much smoother.

Regards the thickness of the foil needed, what do you recommend, 2,3,4 or more layers?

If you have turkey foil then you can do it with one layer of foil and then a hot iron and move it slowly from the middle out with the foil stretched tight. If you see a wrinkle forming in the foil stop and reposition. After a couple of goes you will get the hang of it. I haven't tried multiple layers but that might work even better. If you try that let me know how it goes.

Super job again Andy. Glad I looked at your build threads on the P-40 & Spit. It explained allot.

Hi James

OK, I've had a go at the ironing...LOL, I used a double layer of standard foil and followed your instructions by ironing from the centre out, and I did get it to work eventually. I'm not saying it was easy, it was avoiding the wrinkling that was the most difficult. You mentioned thicker turkey foil, I think that's the answer if you want to do it properly. But thanks for bringing some new to me that I didn't know about, learning new stuff is great.
regards
Andy

I think if I could find a flat sheet of Al about a mm thick I could just stick the iron on it to heat it up but so far I have failed to find anything handy like that. By the way did you like the way the EPP comes out?

I must admit it does give the EPP a much smoother surface for painting, I'd have to fill with and sand with spackle for to get a similar finish and it would certainly take longer than ironing.
