I generally don't use tumbler bases with dry bushings, easy enough to build a base with pillow blocks and larger rods, but my smallest barrel is a skinny metal 6# unit and largest is 40#. For the person with the smaller barrels, I wonder if a small piece of something like Zero-Mat would eliminate most of the noise, since that thin sheet metal is going to conduct it, and even worse if the bushings are brass. They make bells out of brass specifically for it's ability to be noisy. Dry bushings cannot be made silent, but I think a sound deadening material to eliminate most of it will make it quieter than the rocks in the barrels. I'm almost convince the extra loud sound was the everything kind of settling into place. I had to readjust the belt spacing 3 times to find the sweet spot, but I've had both full barrels running for a couple of hours and it sounds much quieter than last night.
The zero mat would go under the entire unit?

No, it's adhesive backed to stick to car floorboards and inside doors, a couple strips on the ends between the bearings would be enough, we used about a 10x10 piece on the inside of the door skin on the doors of cars we restored, about 20% of the sheet metal surface. With a tumbler regular closed cell foam is probably enough. |
