For those of you that use a tumbler, what type of additive are you using to keep the interior of the tumbler from rusting? I've used some soapy water and it works great, but is slowly rusting the inside of the tumbler along with the outer portion of the cage.

what kind of tumbler do you have? we use machine coolant like a cnc machine

PRLdrag240

Sodium nitrite and physan 20. We use this in our plasma table. Good homemade plasma quench

c5R

wd40 as a cutting agent and rust preventative

I'm using a qwick-way tumbler. It's going to take probably 5 gallons of liquid to get it up to height for the cage to splash through it--trying to keep it this on the cheap as I'm sure it'll be $$$ to change when it gets dirty.

I'd recommend calling the company that made the tumbler and ask them if they have a recommendation....barring that call enco or msc or one of the industrial supply houses and see what their tech support recommends for something inexpensive.

I assume this isn't a bowl/tank style tumbler? The compound fluids i use here have rust inhibitors in them.

It's a basket style very similar to this:
