It’s a kit from Caswell, the tank is a 3 gallon bucket. It wasn’t cheap but I bought it to plate some stuff for another project. I can do them in silver or the yellow chromate like is common on bolts

For what it's worth I used a piece of zinc and electrolysis in a bath of water with a little baking soda plus a little washing soda. Worked well too.
I use an old 12V power supply from a computer, capable of supplying a lot of amps (maybe 24 or so). Got a roll of zinc that people use on the roof, from home hardware. It was the only source I could find of a more reasonable price. It's recommended that one uses distilled water. There are several "salts" that one could use to make the bath, the idea is that the water conducts ions if salts are added. A little bit of detergent like washing soda helps to have a finer deposit for the plating. I also tried epsom salt too. The receiver item should be really well clean of grease or oil, and dirt, of course. Many like the receiver item dipped in muriartic acid (hycrochloric acid). That'll clean most rust too. The plating is simply hanging the piece of zinc in the bath, I try to hang it so that the tape of zinc goes all the way around the receiver piece. Zinc goes on the + (positive) lead of the power supply, and the receiver on the - (negative).
The more proper way is to get the right zinc sulfate from caswel, but what I'm trying to say is that I got a good coating using my method too. In fact I experimented with copper coating of tools too. Now that way I got a nice looking coppery pair of pliers.

When I was rebuilding the carb on my old boat I silver coated the inner parts of the carb using an old silver chain I had around as donor. And it worked, using the same idea as above. Of course to do it more professionally you get silver in a salt powder of sorts, tends to be expensive.

I plan on getting the copper coating supplies from them, I’m having issues getting a nice shiney finish without polishing the metal afterwards so I want to try plating with copper first then zinc on top of that. Anyway, it’s fun to try, looks like I have a meth lab in my shop
Had some good weather so went at the painting hard, pretty tired now this evening lol.

The big project got some epoxy primer, hopefully top coat in the next couple days.

It’s a Case of course, 1394. Full size farm tractor, about 65hp, 4wd. Bought it a year ago with a con rod hanging out of the block.

Nice! I think a lot of us would enjoy if you take us on that trip as you fix it up. If you feel like starting a thread on it we have a "My other tractor is..." subforum.

Did some wet sand blasting on the rear wheels. Ran out of sand, can finish up with wire wheel later

That new paint looks great!
I totally hear you about the fun with plating stuff. I too always got a dull finish with all plating I tried. I thought that was normal so a little polishing didn't bother me. Curious about your outcome when you'll do it.

Primed the rear wheels with high build primer. Not sure if I’m just going to top coat them or try and smooth it out some. I got the rust off but it’s still a bit ugly after the PO had brush painted them what seems like yearly, for the entire life of the tractor. To really do it right they’d need to be completely stripped and I don’t want to get into that. I think we’ll have to not let perfection get in the way of good enough in this case. May have to look for some thicker white paint though, what I have is quite thin. Doesn’t hide much. Also forgot to tape a valve stem lol oops.
