Is there any reason I cannot re-use course and fine tumbling grit and the prepolish? After skimming off the plastic pellets and pouring the water off in the yard, it's easy enough to collect the grit. Why shouldn't I re-use it?
If you have grit left, you didn't run the cycle long enough. You're not getting all you can out of the grind. Or are you referring to the gray slurry. If that's the case, it isn't what it used to be - it has broken down by at least one stage.
Some folks will start a batch in 60/90 and let it run for months at a time. The silicon grit keeps breaking down all the way to polish stage. Maybe someone will chime in and let us know how this method works for them. My problem with that method is you don't get the same shaping as repeated cycles in the 60/90 grind would provide - but that could just be my preference. I re-charge with new 60/90 every week until I'm happy with the shape and texture before moving on.
I think some folks use a bit of the slurry from the old batch into the new batch to jump start slurry formation. I've never found the need myself. Most everyone re-uses polish though - it doesn't break down like grit.

Hmm, if it's still coarse grit then yes, you aren't spending enough time in the coarse grind, or you need a better mix of rocks vs. grit carriers aka small rocks, chips. If you still find you have leftover grit then you are using too much. Better to not waste grit if you can help it. I like the idea of jumpstarting the next batch with used slurry. Steve
When I'm rinsing out barrels I let the water run into the barrel and take the rocks out by hand rinsing them off as I go. The tumbling grit settles to the bottom and can be reused. It's not as aggressive as brand new 60/90 but if you have about 25% old grit and 75% new grit you'll get good results. Washing out your barrels this way gives you a good idea of how your grit is being used up so you can time your barrel clean outs better.
Also, if you put an old cookie sheet under the barrels while you're rinsing them out you'll catch a little more grit.

wampidy: I was right, it is there. I will just get your mom out of the house, burn it down and dig through the ashes. Okay, maybe not but you better keep an eye on it. Another way would be to take your mother to dinner then excuse myself to go to the john.
