Hello, I am new to tumbling. For my first batch I used Rock Shed grit that I ordered as a set (with grit for stages 1 through 4). The rocks turned out great. I discovered that the tumbling grit set from Kingsley North was a bit less expensive, so I am using that in my current rotary tumble. I moved a patch from stage 2 to 3 last might and I noticed that the Rock Shed stage 3 grit is 500 aluminum oxide and the Kingsley North stage 3 is 600 silicon carbide. I am wondering if I should plan on doing a pre polish with 1000 aluminum oxide before I move to the 8000 beacuse of this change in grit type. I did not prepolish with the Rock Shed grit, I moved from 500 (stage 3) right to polish with good results. I hope this makes sense. Any advice is appreciated.
