I'm curious too. Have done the deburr/satin finish work with the pyramids. Worked great. Tried the little ceramic balls with no success.
A friend who does tons of vibratory finishing is somewhat convinced it is very hard to polish in the smaller machines. He claims the weight of the media on top of the part plays a role, and there just isn't enough media in a small machine. He said small ones can take up to 48 hours to do much polish.
I haven't tried again since talking to him, but would be interested in a successful recipe for small machines. |
