Actually, I'm just messing around. lol.... a 15 pound tumbler shoud do a fist size rock with no problem, it just needs enough room to move around.

You also need to put sufficiant small material in there to keep it from falling and banging around in the tumber. I'd reccommend material you don't particularly care about, as the large piece might fracture and/or smash them up a bit. You want to make sure the material is sliding and mixing, not churning and crashing in the tumbler.
