Its actually pretty easy to set up an electrolysis tank of just about any size. If you can locate a watertight container big enough to hold your stove. Preferably plastic so it doesn't react, if you can get stainless, you won't need a sacrificial anode.
Looks to me like that stove may fit in a standard 55 gal barrel? If so, then it would be very affordable to set up a tank.
Container doesn't have to be big enough to immerse whole item, halfway is fine. Then you can turn over and do other side.
Great find by the way!
