Folks -
I have an old dovetail saw that belonged to my dad... very poor shape.... I am doing an electrolysis test on it to see if it'll remove the rust. I removed the handle and have had it going in the soda bath with about 1 amp at 10v for a couple of hours. I'll post more as progress is made.
The easy way to remember how to hook up the leads is the RED lead - is the RUSTY one... Put the sacrifical metal on that one.... The BLACK lead is what you want to have be "back in the black"....
More to come!
