I've recently bought a Lortome 3A tumbler to start tumbling rocks from the goldfields.
I have some great pieces of black banded red, yellow and green jasper from WA and some interesting quartz from the GT (some with gold glints).
When I split them to tumbling size, can I then roughly shape them with an angle grinder (ceramic blade) before tumbling?
