They all deserve a WOWWWZERS! The shine, the variety of hardness and material all add to the total package. I see no sense in you even trying to improve your polishing techniques. It can't be done!

Even doing them "wrong" James puts me to shame. Got not one thing to do about James fish. It is all about the ability of the machine. Yes, abrasives/media/slurry plays a role. But the machine controls the quality more than anything. This vibe is so user friendly it is difficult to screw up a load. As I recall the Loto uses an electronic induced motion. Your vibe an offset weight. My assumption is its the shape of the Loto barrel that creates the superior polish. That and being able to tone the Vibrasonic down.

That and being able to tone the Vibrasonic down. The Loto uses counterweights mounted in the fans. The Mini Sonic uses an electromagnet. Nice work jamesp

I found it's limits amygdule. A 10 ounce piece of glass in 100% 1/2" quartz media. It polished fine but had micro damage from the media. Next step is to try 1/4" media for more support points.

I own the UV stuff. I am uncertain how shiny my rocks are. I am not nearly as fastidious in clean out between grit changes as I could be. I do not have a dedicated polish barrel. I do not keep records on polishing. My rocks suit me fine, and that is really what matters.
I enjoy following your quest. I would not be surprised to see you faceting next. Find a challenge, whip it and move on.

I would not be surprised to see you faceting next. While I have no doubt that he could do so, I don't see it happening. Jim is too much of a giddy up and go type. You are just as likely to see him doing needle point as faceting - IMO Maybe when he is 90 or being rode hard and put away wet finally settles him down.

youp50 captbobMy vibration mechanics professor would have failed me on this vibe project. Looking back on the issue with excessive vibration was basic and the solution was way basic. Gentle vibration environment should have been solved in 15 minutes. may purchase a used UV to tinker with. Need to try to tune one of them. If any one finds a deal on the smaller UV-10 let me know. I'll try to tune one.

Sure helps to have a percentage harder Mohs 7 media(or ceramic media) to do a better job of breaking down the abrasive.

I'll try to tune one. I will get back to the rock shop for a week or so. I guess I have to start fooling with glass. I did pull the trigger on some clean ceramic media from Rock Shop. I decided I needed a 4 # bowl. It still is bruising glass. I am reluctant to put a plate of steel on, I would own the only UV in existence that would burn out the motor. Probably need to look into the mechanics of the machine to decrease weight offset.

Probably need to look into the mechanics of the machine to decrease weight offset. Keep this in mind. The Vibrasonic is designed from the factory to do 8 - 12 - 14 - 35 pound hoppers. Counterweight setting a lower '1.2' for 14 pounds, counterweight setting more aggressive at '3.0' for 35 pound hopper. What damages the Vibrasonic is running it with no hoppers or too little weight. So in the case of the Vibrasonic adding weight reduces stress on the machine. Not sure about the UV design. Most spring type vibratory tumblers can handle more weight since the springs isolate the load. Less weight in most designs can make it shake itself to destruction. Unstable. Only reason I mention this is I never had one bit of luck lowering the counterbalance amount. It still bruised the heck out of glass. Even small 1/2" pieces. Adding weight at the right place did the trick.

Unstable. Do you remember this thread. Page 1 forum.rocktumblinghobby.com/thread/80687/disbelief-super-tacky-kaolin-slurryThe motor for the UV model is mounted vertically with the counterweight at the bottom.

Raytech AV-75 industrial metal vibe. I would start by adding a 1/4" to 1/2" thick steel plate weight to the bottom of item 9, the motor plate. Diameter just past the edge of springs. That should directly oppose the launch and retraction forces of the springs, therefore their travel(amplitude). Probably, maybe. This is probably the basic design of most bowl vibes.

Good looking bunch, James. I'm always a fan of mixed batches, and a machine that can lay a polish on such a mix. Well done!

Good looking bunch, James. I'm always a fan of mixed batches, and a machine that can lay a polish on such a mix. Well done! Mixed batches in a rotary is a problem if you don't cull the soft rocks out before they disappear. Mixed batches in a vibe simply don't have that problem since fast wear is not an issue. Matter of fact, throwing a few soft rocks in with the hard ones makes fine slurry to pad the whole lot. They seem to serve as slurry pellets. Happy New Year Randy.
