I derusted another file tonight by electrolysis. The setup was topologically and electrically identical to Sunday’s, but the file was much bigger. So I put everything flat in a large, low tub. The current was a little lower (4 Amps), but it got the job done.

Sorry, no pics tonight:

1. I was doing this along with several other things.
2. mia_mcdavid was using the camera for fabric stuff.
