Using two of these dividers I can polish three ~2 pound rocks separated at the same time. Keeping them from banging against each other. Three different batches could be run at same time like soft medium and hard. Cool beans.

One question though , do the dividers seal good enough to keep coarser grits from escaping into the finer section ?

So I do AO 80 all together, clean out, then all 3 compartments on AO 14,000. It is 1/8" PVC and wedges well due to flex. Sorta deformed the soft polyurethane a bit, but deformation went away after a few hours of removal. Seems reliable.

Still good that ya can do more than one big one at a time . I have to be careful with anything close to a half pound in the gy roc . Put two in on opposing sides and they always catch up to each other and clog the action .

If there is a minute possibility of any arrangement no matter how slight the risk the vibe will manage to make it happen. It will seek Murphy's Law. Even running the dividers, more slurry piles up more to the right side. Does not seem to cause any issues though. How long does it take for A to catch up with B ?

Usually it happens within an hour or less . Wouldn't dare try to put a 2 pounder in it , the donut shape on the gy roc doesn't allow for oversize rocks . That is where I give the advantage to the UV 10 , the center cone is smaller diameter on that one . I could maybe put a couple bigger rocks in if I left out a bunch of mediums and added more smalls .

I was trying the two divide the round vibe for a UV-10 it never worked. So I tried a vitamin bottle, different grits in each bottle. Might be a option for your vib.

The movement in a gy roc doesn't allow for dividers or other mods . The load is moving in two directions at the same time if it is loaded correct .

Good idea, glad to see it works well. Do you get the same polish quality in each segment as if you were running a bunch of smaller stuff in the entire tub?

Good idea, glad to see it works well. Do you get the same polish quality in each segment as if you were running a bunch of smaller stuff in the entire tub? Sure seems to Larry. I ran several batches with no large rocks with dividers in. Was just to lazy to remove the dividers. No difference in polish quality. The smallest compartment rotated slower guessing due to restriction. As mentioned, the right side was wetter than the left side. But not to a fault. The dividers prevent the big rocks from piling to the right side, but does not prevent the lion's share of the slurry from moving to the right side. Maybe the slower moving smaller compartment would be better for polishing soft rocks. Maybe the right side with the thicker slurry would be better for polishing soft rocks. Maybe the smaller compartment should be set up on the right side where the thicker slurry moved to for soft rocks. It opens you up to some trails for sure. One thing for sure, you can run 3 sections with tiny gentle media for each of 3 big rocks. And let me say, those big rocks with small media flat out take a fast polish using AO 80. Right out of unbroken SiC 30 from rotary to dang good polish in 1.5 days with the AO 80. Those big rocks must have higher rubbing forces. Or is it compressive forces ? You get the idea when you turn the vibe off - forget about removing the big rock with your fingers. You have to use a pry bar to remove the big rock with vibe turned off, amazing the wedge forces. I have to pull the big rock with the vibe running, only way when using fingers. Think about that for a second.

That problem has been sticking in your craw for a while. Knew you'd get it worked out.
