I use old saw blades as electrodes. I also have a commercial fish cooler ( 6'x3'x4'tall ) for the larger stuff
Negative goes on the object, positive on the blades ( you need some kind of steel plates to complete the circuit) I added some blades hanging into the frame cavity - its pretty much a line of sight process. You need "washing soda" - kind from the supermarket for $3 - some people also use molassis etc. Baking soda does not work - I also add some detergent as a degreaser. If you are removing rust/paint - I leave it in over night. For just stripping paint - a few hours will do.
I would not use one of those expensive new fangled computerized auto chargers - just your cheap run of the mill 12 or 15 amp charger. I run my big tank with an industrial power supply - but thats because I like to really see it bubble.
PS - you can also use an old computer power supply - the 5 volt output will even work - most have more than enough amps.
I only cabinet blast small parts now. ( or if they are not steel - don't use ERR for aluminum,copper or brass) Once your discover & perfect ERR - life is good - it saves so much time, effort & resources.
