I used to use a battery charger for electrolysis, but a tech at the museum in Indy working on a civil war cannon told me that they put way too much power into metal and cause micro fractures that won't be evident until they become a failure point. They clean artifacts with only a few mA of current. Takes longer, but less potential for damage. Now I use a lab power supply I picked up on Amazon. I start the current at 0 and slowly turn it up till I see the first hint of bubbles. Don't know if it's something to worry about here or not, but might be worth looking into.
I love these old engines keep up the great work I can't wait to hear it run
you give me so much inspiration to work on my engines. Keep up the good work.

I use phosphoric acid and water dilution, or my bead blaster and fine glass bead
