I used a jig saw to cut out the lid as shown.

I cut the rebar so I would have about 4" sticking out the top.
This allows me to attach the acorn style ground clamp,

(NOTE: Home Depot may not have this kind of grounding clamp but you can get them at a good electrical supply co.)
I used 8 pieces of rebar to get better coverage around the item be cleaned.
I wired in a loop fashion using #10 stranded copper wire
(I had this on hand) you can use larger if needed or wanted.
I did not cut the wire at each rebar connection just looped it and
attached them on to the next piece of rebar.
Continue this all the way around the bucket lid. When all the way around just connect the last two pieces together.
Here's a shot of inside the bucket.
Your now ready togo to work just add water and your TSP or washing soda & batterycharger.
I used a wooden dowel to hang the piece to be cleaned from.
Using a piece of copper ground wire to make the connection to the piece
being cleaned.
Everything here can be bought at Home Depot or any other good Hardware or home supply. My intent was to make it easy for anyone to build an Electrolysis set-up. The acorn nuts may be the only item you would have to look for at a electrical supply house.
I was getting a current flow of 1 amp but I did not clean the acorn
clamps or the rebar and both needed cleaning up! I guess I was in a
hurry to get some pictures! I'll do that a little later.
This design allows you to disconnect the battery charger, remove the top and pour out the contents for very easy cleaning!
