My new drums!

This is how I did it. This might not be how you want to to it.

My bearing edges were old and beat up, so I figured it couldn't hurt. My Dad had a large table saw with a nice machined flat surface. I'd put the shell on it and shine a flashlight inside the shell and looked to see if light would show through on the outside. If I saw a gap, I'd take the shell and carefully spin it on the concrete floor to sand it down to be flat and level. I'd keep doing this until the gaps were gone. Then I'd paint just the areas that had been flattened down by the concrete. Then I'd carefully file the bearing edges down until that painted area was a little pinstripe at an even distance all the way around the shell, making sure to keep the angle of the bearing edge consistent. Then I hand sanded it to make it smooth and even, then ran some paraffin wax around the edges and buffed them.

Viola!

Thanks! My first thought had involved taping sandpaper on our concrete garage floor, but I could probably use a flat part of our concrete driveway that has more surface roughness to do the first cut. Using the paint is a great idea if I try to re-work it by hand, which is how I made the bearing edges to begin with.

My other idea involves a router with a pivot kit and installing braces and a pivot suface in the shell. Frankly, that's a lot more work.

The idea of grinding it flat with the concrete floor, painting and reworking by hand sounds quicker and easier for my level of skill.

Thanks!
