Does anyone else end up doing this?
I currently have some Wisconsin Moonstone that has been in 120/220 for 3 weeks. Why? Because time, weather, etc., has not allowed me to do a clean out. Have some other hard rocks that have been going for 6 weeks in 60/90 due to same.
I usually do not worry about extended tumbles after stage 1. Some hard rocks I let go in stage 1 for months.
Have you ever had some major things happen after a lengthy tumble in any stages? So far I haver been lucky.
I normally do 60/90, 120/220, 400/600, 1200, and 12,000 in a rotary.

For the same reasons, I have also left things tumbling for extended periods. Not had any problems yet, but I am pretty new to this, and mostly do cheap, local rocks. Nothing fancy.

Not that long ago I wasn't feeling well for an extended period of time and was always tired and physically weak. While we did not stop tumbling, and A.J. kept things going, there were times when some of our barrels would run anywhere from 3-5 weeks before being cleaned out. The only thing bad that happened was that it was a far from efficient grind and the slurry was usually a thick pudding but other things were a priority then. Would not recommend this for any fragile materials though.

I have done this due to cold weather and have had no adverse affects. I have left 500 AO going for "too long" (in my book, there isn't such thing) and had the stones get a pretty satisfactory polish. I will run them through 14k for a better shine though.

The only time I've had an issue is with fresh sharp material in coarse, where the entire load is new. The space available in the tumbler increased so much that the rocks were doing more smashing than grinding. It left a lot of them bruised pretty bad. Nothing another coarse run with a proper fill level couldn't fix. Another issue with coarse is if the slurry forms a paste that glues the rocks to the walls, leaving a donut hole in the middle with rocks banging around. So my issues with extended runs only seem to be with coarse, not later stages.

...Nothing another coarse run with a proper fill level couldn't fix... One of the best things ever written in this forum! That is what it's all about and how to get quality results.
