Quick question. Can you skip from a 36 grit to 220? (taking under consideration of grit breakdown)

No experience using 36 grit here. If it is run long enough to break down completely I can't see why you couldn't go to 220.

I've never used 36 grit but tried 30 grit some time ago. I found that in order to get all of the grit to break down I had to use MUCH less water and run a 15 lb tumbler at twice the normal speed. I added water when I heard that the rocks were not tumbling right and got some pretty thick slurry in the end.The 30 grit down down completely in about 10-12 days. I though that using 30 grit would speed up the tumbling process but it really didn't. connrock

Quick question. Can you skip from a 36 grit to 220? (taking under consideration of grit breakdown) I almost tried this... After getting the rounding I wanted with the 36, I opted for 2-3 days of 60/90, just to smooth out the scratches on the surface. I was afraid the 220 wouldn't smooth the rocks all the way.

Thanks everyone. 36 grit worked really well. But,I think i'll go with "tobias" idea and run it in 60/90 for a while.
