I also have one of those sand blasters. Bought one at Harbor Freight last fall after seeing it on the forum from another member. Can't remember who it was. CRS. It works very well for small items. I bought mine to use for soda blasting but have also used sand in it. Works very well if your not in a hurry.

Sometimes, I amaze myself !
If you can not learn to do it well, learn to enjoy doing it badly.
