I am in the process of making several tools for use on the lathe, and
hope to sell some of them at cost, I would like to be able to etch
the shaft with a logo, as well as polishing the shaft. I have access
to a faily well equipped high school metal shop(was thinking of
mounting on one of the lathes to polish.
Hay Raid,
You know, I was thinking about Roadmarks just about an hour ago. How
it could be a good movie. Anyway, get that stuff they use for ecthing
circuit boards at radio shack. It's ferric chloride. Stains fingers
real good but will etch steel. Lacquer or wax the part and scratch
through to make your image and then submerge, agitating once in a
while, and check now and then 'till it's deep enough.
Cheers,
