I had the same problem, The problem is that the tumbler lid is to smooth and there is no grip from the spinning wheel. I solved this problem by taking a kitchen steak knife and roughing up the edge of the tumbler where it rides on the spinning wheel. Works great now. Best of luck

Nothing high tech here. Try it without the o-ring. If the water does not start to leak out in the first 3 to 5 minutes of tumbling you will be ok. Stop it every day to check the water level.

Set the whole thing on a cookie sheet in case it does leak when you are not watching - you don't want a bunch of rock dust and polishing grit on your table or floor in the morning.

You will not damage anything by trying it without the o-ring.

Sounds like it has a build up of dust. They need to be blown out with air from time to time
