Haha I didn’t know people would actually be interested in paying for an aluminum can with fins xD
Looks like the hardest part would be making the threads on the inside of the cylinder, which would 100% require a cnc lathe rather than manual.
If I do try to make one and it turns out good I’ll definitely make some more and let you guys know 
Does anyone know what aluminum regular flashlights are made out of like the ones from nitecore, fenix, etc…?
6061 or 7075?
Most of them just say aircraft grade aluminum, and wikipedia says that that usually refers to 7075, but 6061 and others are also considered aircraft grade.
I’ll probably make it out of 6061/6063 either way, since 7075 is like $500 for a cylinder large enough for this type of light.
Makes me realize why these lights cost thousands of dollars…
