!!!I’m sure most here will know this tool, a cat’s paw. Invaluable in woodworking and home repair, but has been very handy in this project. Great for prying, but the newfound use is rust removal. Great as a scraper and the curved end provides leverage when picking at heavy rust. I’ve had this one for over 20 years and haven’t broken it yet.
Back to rust.. the surface of this plate is irregular because of rust and pitting. When removing rust with a wire wheel I find sometimes the raised rust surface gets polished and shiny, looking like good bare metal but if you pick at it there will be rust underneath. I think this backing plate will be the guinea pig for the electrolysis and I’ll see if these bumpy surfaces will be reduced by the process.
Putting more work into this piece is strictly for experimental purposes because a coat of rust paint now would be good enough to put it back into service.
You win the prize!OK it's been a few days since question was asked back in post #47 about the thingy in brake drum.
So I'll make what my thought is about the thing with the drain pipe. I'm guessing it's there to catch any oil leaking from the axle seal and drain it away from the brake shoes. Not sure if they still had them in 1966 as that is the oldest VW I think I ever worked on.
Will the battery supply too much current? I liked how it was “cooking” but thought maybe it was too much. I did notice the electrolyte was warm ( the bucket was outside in 3C temps), but I started with very warm water too.use your smart charger AND the battery that'll fool the charger.
I have and use an old school 2/10/50 charger for electrolysis. usually the 10 amp setting, it'll warm up the bucket over a couple hours. Warm water really improves the rust scrubbing action too.
True with Evaporust also I leave the part in a bucket near the wood stove in winter. Out in the sun in summer. About 60F the action is very slow.

Will the surface area of, distance between cathode and anode figure in also?Current is a function of resistance. Resistance is a function of how much soda you add to the water. So no, the battery will only supply as much current as the water/soda mix allows.
Thx. I eyeballed the amount of soda and probably have double what I should. Should I remix a new batch?Current is a function of resistance. Resistance is a function of how much soda you add to the water. So no, the battery will only supply as much current as the water/soda mix allows.
No the soda will only dissolve to saturation (the ideal mix) any extra will just sit in the bottom of the bucket.Thx. I eyeballed the amount of soda and probably have double what I should. Should I remix a new batch?
Was wondering about the size of my anodes. Could they have too much surface area? I have 2 @ 2.5” x 14” and 2 @ 3.5” x 14”. If too large it’s easy to disable a pair or more of them.Will the surface area of, distance between cathode and anode figure in also?
