In this video I make a small sign with a block of aluminum and acid. I'm sending this one to Jimmy along with my SASE for one of his stencils. Thinking about it afterwards, I should have used Blue 3M Tape instead of the green.
I can do a longer video with more detailed how-to info if you guys think it would be helpful. I skipped showing a step or two to make this video short.
Questions, comments and requests are encouraged.Thanks!
Of course use caution while working with acid of any kind (sad that this even needs to be said).
