Can you make Seaglass in this Tumblr?

I put thicker glass pieces in the tumbler The glass came out with rounded corners Very happy with it

The tumbler was so quiet for the first 5 days, then the knocking sound began. I’ve double checked the lid, etc. and it’s still happening. Why?

I’m guessing that it’s either the rocks or stones inside the tumbler, could be there is a small leak and there isn’t as much water inside. That was what happened to me. It could be the rollers need oiling also. The whole process is pretty simple, there aren’t a lot of things to check. Good luck! It’s a great hobby
