I found a plastic container at hardware hank.. I had the metal strap for the anodes and steel wire on hand. Copper wire was from a used bit of romex I found in the shop.
I could not find washing soda so I bought a cheap box of baking soda at wallmart. See this link on converting baking soda to washing soda. http://naturesnurtureblog.com/2012/05/08/ttt-turn-baking-soda-into-washing-soda/
The ammeter on my battery charger was busted during a move back in the 80s. While shopping at TSC I found one with a 2 amp trickle charge feature for $17. This was a want more then a need as I could have used a multi meter.
It was quite easy to setup. This was at about 4:14PM just getting started.
After only 11 minutes things were moving right along. Very short video showing first the sacrificial anode then the part being cleaned.
I could not resist so a few minutes of 5 PM I pulled the part out and gave it a quick once over with a brass brush.
After just a few hours in the electrolysis setup it is done or nearly done cleaning. The big clue is that the water clears and the bubbles mostly stop.
I moved it to the heated ultra sonic cleaner to see if I could get some of the black residue off. The used water shows it is working.
At this point I stopped. Whatever is left on the pulley will help to keep it from rusting. I am not sure why but the front
Random ramblings Information is sketchy about the process. It would seem that a higher energy flow speeds up the process. The problem is that creates heat. I am wondering if pulsed current at a higher voltage would give faster results then a stead DC at a lower voltage but with the same power average power level.
For example instead of using 12V @2A continous one could use 24V @2A with a 50% duty cycle. The heating would be the same but the parts see twice the voltage potential. In reality we might be looking at frequencies in the khz range.
Scored some washing soda at the Dumas Walmart today. Also picked up 4 more lbs of baking soda to try soda blasting with. Currently cooking the muffler and the trash screen from 3LB #1.
Need to hook up an ammeter to see what is really going on.
After 18 minutes the water has already changed color and the anode has started growing wiskers.
At 5 hours (12:30 AM on the 10th) the solution had noticeably cleared.
The solution is not getting any clearer so I just put the screen back in without cleaning.
I justed watched a youtube where a guy from east Arkansas used carbon anodes. No brown scum! I have no idea where to get cheap or free carbon sheets or rods. Remember this is a low budget operation.
