Can the UV-10's bowl be used on a UV-18 or will its lighter weight cause the action to deviate to such an extent to cause abnormal wear?
Are the contours of the bases the same (will both bowls rest the same on the foam pad)?

Also... I purchased a sheet of 1/4 inch rubber foam gasket material and cut forms to use under the UV-10 Bowl and under the top lid. will these change the vibratory action any?

The UV-18 has a larger diameter threaded rod so no. If I had a UV-18 and found a UV-10 bowl for cheap I would drill it out to use on the 18 but you would have to change the unbalanced weight on the shaft to settle it down a bit. I have a 10, 18, and 45 and have adjusted the unbalance on all of them to settle them down because I didn't like how aggressive the were........................................MrP

I have an Industrial UV-18 on the way from The Rock Shed, along with an extra bowl to dedicate for polish only. I will NOT drill out the holes of UV-10 bowls so they work with the UV-18 - I will still be using the UV-10 on occasion. I would rather not do any re-balancing either (people with my mechanical skills should leave that stuff well enough alone - don't tempt the fates! ...Hmmm... How do you spell Klutz?) I also have a new Industrial UV-10 bowl on the way, to replace the one that blew out this last Wednesday. It was a very messy 3-inch break on the bottom of the bowl - which was only 3 months old. I could have continued that aborted run (8 lbs Agates and Quartz - running at 600 grit) using the dedicated polish bowl, but decided to wait for the UV-18 to arrive. The UV-10 will go on the shelf as a spare. Can you see any problem in adding the extra 1/4 in. foam rubber gasket under the bowl and under the lid? Will that dampen the action any? Thank you again for your help! |

Thank you again for your help! I don't think the extra foam rubber will make much difference because the bowl has to be bolted kind of solid anyway so it fits tight. I thing the foam is more for making sure the bowl doesn't move around. As far as foam on the lid I don't have any. Found it to be a pain so removed it and all is fine.
As far as re-balancing the UV-18 and UV-45 have an extra bolt on the offset weight to add more unbalance. On the one of my UV-18s I drilled and tapped the back side of the weight to take a lot of the vibe out of it. I am going to do the same to the UV-10 because I just can't get it settled as much as I want. I change the unbalance depending on what I am tumbling. Agate In 220 grit let-er buck, obsidian in polish not so much.
I am wondering how you blew out your bowl in 3 months. My first UV-18 bowl lasted over 2 years 24-365 running 220 through polish. One thing I did do is when that bowl started to wear thin I put a layer of thin Super Glue in it. Just pour the glue in and roll it around until it is all covered. You will want to do that outside because the fumes can get bad.
Good luck. The good thing is it only takes years to learn it all. Well maybe the good thing is you NEVER learn it all. Have fun..............................MrP

Thank you for the info MrP. I really did not expect such a disaster to happen so soon.
My start using a vibe was a rocky one (no pun intended...). There were a lot of freeze-ups caused by either not enough water in the mix, or to much added water. I did not help the bowl much by cranking down on the wing nuts to keep them from unscrewing with the vibration - lock washers stopped that from happening... but still it added up to more stress on the bowls integrity.
I DID help the bowl by running all rough through the tumblers first to knock off the sharp and rough edges.
I guess I should chalk it all up to a learning experience.
