When I make my penny stoves, I am having a hard time getting a good mating between the fuel pot and the burner lid. I crimp the bottom edges of the burner so it can fit inside the fuel pot and press fit them together. but always seems that I get a "sharp" edge from between two crimp area and it "scores"/deforms/"can't remember the correct name" outside area and prevents a smooth finish and fit. Any idea how to fix/prevent this type of blemish(es).

I might just be trying to be a perfectionist and could just use epoxy to fill in the gap corrected inside and don't worry about outside. I can get my stoves to work but I am still in the experimenting stages. I even got one to work well withmy jetboil mug, just watch out for the cover as it stinks when it starts to burn lol.
