The PTA is having a silent auction next month, so I’m making a few things to donate to it. The school’s mascot is a cheetah and paws are everywhere. I decided to etch some copper with scaled-down versions of the school’s iconic paw print sticker.<\/p>\n

I like to use wax sheets that were originally designed for investment casting. Wax makes a great resist for the etchant. I put the design right under the translucent wax sheet and cut it out with an exacto knife.<\/p>\n

Update: So the second time I check on it, I see that some of the wax pieces are floating on top of the acid bath.<\/p>\n

Back to the old drawing board. But first, remove the rest of the wax, pickle it, then tumble it in steel shot. Thinking about using permanent marker instead of wax.<\/p>\n<\/div>\n
