1 Has anyone here tried it?
2 Will it work on recessed areas, like the slots of castle nuts?
3 Is there a model available that is reliable and not terribly expensive?

I havnt tried it but I think I will try it on my brass contacts for a coil box I am rebuilding. Works great on rifle brass. I will try some bolts and nuts also.

Here's an approach that might appeal to mister thrifty:

I'd think an Ultrasonic might be a better ides Steve. Harbor Freight has them . Or you can shop the gun parts places like Brownell's or Midway USA. Then see what Amazon has. Sometimes they have them used.

Just remember that rock/gem tumblers are designed to take off all the roughness and polish all surfaces. I.E take off all the clean sharp edges such as on nuts and bolts and leave smooth rounded surfaces. IS THAT WHAT YOU REALLY WANT ?

I throw nuts and bolts and a few handfuls of sand into a cookie tin and tape the lid on for security, then I bungee the can to the rear wheel of my little tractor and go out and mow. Sometimes the crusty stuff needs a second ride, but it works.

Marc, I like that Idea. I have seen a gas tank with inner tube around it in the dryer to clean it but my wife would not let that happen... I think I could get away with the mower trick.

I have done it. I purchase, a jug, of some type of plastic triangular things for rust removal. I used ot on small parts. If you have alot of time it works, I think I had ot running for 2 or 3 weeks, before I got tired of waiting, for the parts.

The more you have to mow the better each session will work. The area I do takes about two hours. I use pretty aggressive blast media but the metal finish comes out fine because of the slow impact.

Steve, I used my RCBS tumbler on some rusty wood screws. I used walnut shells for media. Took rust off and made shiney. Dark spots where rust was. Did not remove paint. I will try sand next. Took about 3hrs. The brass came out like new. The media had to be scraped out of slot in screw head but it came out easy. Will post some photos when I get home from work.

Steve I got a drum tumbler from HF years ago. Does small stuff well. Cheap and the belts are available from them. Gary https://www.harborfreight.com/3-lb-rotary-rock-tumbler-67631.html
