Yeah I'm really taking my time on it and not scratching the steel or anything, it looks pretty damn professional so far (I even MEASURED before drilling holes!), sort of like the Volcano Vaporizer. The design itself isn't much more advanced than the basic glass jar soldering iron model, but it looks a lot better. The only problem is that my largest drill bit is just a bit too small for the soldering iron and I think the next biggest size (not a twist bit, but one of those cylindrical serrated edge types) would be way too big, so my idea is to get some little files and carefully enlarge the hole manually til it works.
I call the prototype 'Sputnik', even downloaded a NASA-esque font for a stencil.
UPDATE: It occurs to me that I could alternatively use a step drill bit to make the holes.
