Not sure if it will stay put. Cut it to fit after a good many iterations. It is wedged darn stiff in there. Material is 1/8" PVC. Simply to tumble 2 big rocks at same time to keep them from crashing and causing frost. With stones and media on each side the forces should balance. Wood wedges to increase compression. I want to be able to remove it. Or add another for 3 compartments.

I think I would add the rocks and fill to the brim with water and sit it over night. It would give the wedges time to swell. Drain and fill in the AM and let it rip. Best of luck

it·er·a·tion ˌidəˈrāSH(ə)n/ noun the repetition of a process or utterance. I asked for that. Used in context 'keep hacking away till it fits'. "Slowly getting closer to target with each attempt" To keep plugging answers into an equation till you get the correct variable.

Best of luck Ya cut up a perfectly good welcome sign . Hope it works , think the wood shims would vibe out . Will find out soon enough youp50 and wigglin. Got put into commission not 10 minutes after those photos were taken. Watched it for 5 minutes and all seemed well. Pushed on it and it did not want to budge. 1.4 pound rock in small side and 1.7 pound in big side. The 1.4 pound rock fit rather tight. I used smaller media on that side. It still rotated slower. Welcome to the forum youp50.

I will be curious to see if the wedges hold. Seems the vibrations may work them loose.
If you could fashion the same thing same as what you got, except with two short wings on each end, then a clamp or vise grip hold each wing in place and the barrier would stay. Not sure how you bend the PVC, probably not or maybe melt PVC wings on to the barrier.

Personally, I don't quite see the need for the wedges at all. The divider is bigger at the bottom, so it shouldn't ride up; and I'm thinking that a full load on either side of the divider ought to keep it pretty much in place.
Will wait (anxiously) on test run results. No need to fix something that ain't broken.
ETA: in other words... pull the wedges and see what happens.

Not sure how you bend the PVC, probably not or maybe melt PVC wings on to the barrier. H Henry, I have both 1/8" and 1/4" PVC plate. The 1/4" is totally rigid, however the 1/8" flexes a bit. I had to use an 8 ounce mallet to hammer the plate in place with light blows. The PVC plate has a bow in it due to compression. Nice wedge fit. I could weld a new cover with drop dividers going down to the bottom of the hopper too. captbob, it is wedged in there tight. The 1/4" thick polyurethane liner may get an indention over time. It is too small to fit on the other side. so the hopper is not consistent along it's length. Will cut next piece slightly larger, using iterated piece for a pattern. Iterating is common practice around here. Can be dangerous process if method is used on wife. But done intentionally it makes for exciting results.

You posted a picture a while back of a lid you made (welded) with two dividers on it. Why didn't that work?

You might also try some rubber shims. Don't know that they would be dramatically different than wood, but they might absorb more of the vibration without shaking loose. I think you will need some sort of shim, simply because while it can't go up, it could tip to the side, and ultimately allow everything to circulate together.
You could make a slot in the middle of it and then make a cross piece that would hold it upright (also with a slot) Somewhat the same as my crude illustration below: IIIII I I IIIII II II IIIIIII III III IIII IIII and IIII IIII IIII IIII IIIIIIIIII III III IIIIIIIIIIII
That would allow it to move to the right and the left, but should keep it stable enough that it wouldn't tip. You could even make that crossmember the width of the vibe and put the slot (or slots) where you wanted to hold it in place laterally. Good luck!

There is little pressure on it since the rocks roll parallel to it. I thought about cross members. Did not know if it would hinder the 'rotation' of the rocks. There is a serious wedge force being that the thin sheet bows and wedges quite well.

Well, divider did fine. Funny thing, the rock in the smaller compartment was tight and barely rolled with the media. The media was passing by it rapidly. And it got the better polish. Perhaps because of a lot of relative movement of the media scrubbing across it. Video coming. The other rock had a few pin point bruises from rotary, so I added AO 22 to hopefully shave off the bruises. After 24 hours I will add other rock to small compartment(after AO 22 breaks down some. 18 hour AO 80 buff after coming out of SiC 30, small compartment, starting to shine. Needs another day in breaking down AO 80. Check it out(bad photo but reflection apparent):

Doing well. To get divider too fit tight it had to be shifted to left. Hopper is narrower on that end. No problem, got pattern, can make more.
