Thanks Don. An etching machine is still on the short, or rather long list of things to get, so I am still using a battery charger. I have professionally made stencils from Ernie Grospitch but I believe I was burning them trying to get a good mark and put them away until I get a real machine. For now, I am using single use stencils made of vinyl graphic material(the kind you see in car windows). A local sign shop I found cut me about 100 stencils for about a dime a piece.
