Hey Gene, forget about the rebar if you are cleaning anything bigger than a screwdriver. Your sacrificial anode needs to have more surface area than the rusty part. The small anodes have to be cleaned constantly, and I mean like every hour, if you are going to get anything done. If you get a piece of thin steel sheet and literally line your plastic barrel with it you will have massive surface area, and then you can control the amps you put to it instead of trying to get enough amps to work. And with a lot of surface area I will almost garauntee that it will clean anything that will fit in your tub before the anode needs to be cleaned. And the liner style anode is omni-directional, you don't have to fool around moving your parts to face the anode. It seems to like line-of sight at first, but given time it will work around a lot of corners. If you are cooking an assembly instead of a single part you need to move the connection around on the assembly occasionally, when it cleans the part it is connected to it will break contact with the other parts and stop cleaning them, if you do a stuck hard rod and piston for example and connect to the rod it will eventually stop cleaning the piston and the rod will be super clean, you need to connect to the piston for awhile. I throw most of one box in 50 gallons. I think 6v will work, I use 12, have pulled 60amps for 3 weeks with about a 2X3 piece of a 300 Chrysler hood for an anode, cleaning an Economy engine in a 300 gallon tank. Once made an 8 inch piece of irrigation pipe for a vertical tank and lined it with sheet steel to do a Hopkins and Allen .22 rifle that was rusted solid, ran at 80 amps for a day and a half, when I pulled it out the water was 180 degrees and the rifle looked like fresh machined steel, every piece came apart like it had been screwed together just minutes before. A lot of guys say that it is too much amperage if you are heating the water that much, and they are probably right. I like big old chargers, buy them at garage sales and auctions, and let them run untill they won't run anymore. Keep in mind that you are giving off Hydrogen gas.
