Thanks! I knew the 22 years I served in the Navy meant something! I used to do maintenance to hundreds of these drinking fountains, I know them inside and out. Once I get moved into my new place, I'm setting up shop and going to buy some titanium tubing or a coil made of it to run in the tank for the heat transfer. probably going to run 20 gallon cooler size tank to start with.
I picked up several large lead strips that were counter weights for something where I work to use for cathodes, and I even found a step plate made of 6061 T6 aluminum for a cathode, at least I can see which performs better.
I mostly plan to anodize aluminum Pop rivets (many of them) but also larger pieces and if there is enough interest, maybe step up to even larger pieces later.
Have a good one!
