Re: Tumbling Gemstones
You don't really want to let the tumbler stand idle for any long period with rocks and grit in it. They tend to "set up" a bit. You might need to find a place out of the way since they can tend to be a bit on the loud side.
Wire sculptures are probably a bit too delicate to polish in a rotating tumbler. The ammo casings reloaders use tend to be polished up in a vibrating "tumbler".
You might want to contact a local gem & mineral society as they will often order grit in bulk for their members. If you have a local rock shop, they are likely to carry grits and polishes.
Also a google search for : rock tumbler abrasives
will turn up many links.
