My tumbler won't turn. Tried unloading some rocks
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
