Picked this up at Tractor Supply for $99, cheap Chinese junk, but gets the job done on small items.
These were calipers from a junkyard I got for $15 each, forgot to take 'before' pictures, but they were almost solid black from the years of brake dust.
Now I can get them powder coated.

 

nice find, whats the cost to run it?

 

I already had an air compressor, set it on 60#.
The media lasts quite a while I am told, and it is not expensive to replace.
I also bought an extra set of ceramic tips and an air dryer for the compressor along with a male and female air connector.
Total bill was @ $160

You can get all sorts of media, glass bead is the recommended one, but the store didn't have any. I got a 50# bag of Black Diamond 40-60.

 

That is a cool and useful tool George. It will probably pay for itself after just a few jobs.

 

Yep.
Already knocked $40 off the powder coating estimate I got.
