>>1623415I have a trangia 27 and I've lost the spirit burner. I do however have the spirit burner for the swedish army trangia that I want to fit. I have to widen the central hole in the windshield by 15 mm. I don't have any experience with metalworking, does anybody recommend a more precise tool than a ruler for measuring? I was probably going to use an ordinary hole saw drill bit for wood on the windshield as the aluminium is very thin (I'm not too fussed if that would fuck up the bit as I only got it from Lidl--I'm more concerned about warping the aluminium).
