For this, we are once again in the kitchen. Need a plastic bowl, some PCB etching solution, a piece of brass.....and some other stuff,........
Used a sharpie for the test piece
Radio shack solution, yes they still actually still sell useful stuff.
It soaks the brass in the stuff.
Took it out of solution, cut to shape. painted it black & sanded the parts, the sand paper will remove the paint from the high areas where the sharpie.
The idea was a emblem for the muffler.
Annnnd anything that remotely looks like a gun to my Daughter, she has to shoot my son with.
