Re: Flatning/Truing bearing edges
I've used a 24"x24" piece of plate glass covered in sandpaper. I use regular sand paper and spray the back with Elmers spray adhesive. Works like a charm and only costs about $25 total. The plate glass is not perfectly "flat"......BUT, it's as close as most drum manufacturers get. Within about .002"-.003", as measured with a machinists edge. The key is to leave the shell in one spot on the glass and spin it like a steering wheel. That way, it doesn't matter as much (the bearing edge is always being referenced to the same spot on the glass at all times). If you color the edge with a Black magic marker occasionally, you can watch the high & low spots as they are sanded out. I then re-sand the bevel back on the edge with sandpaper wrapped around a drum stick. I've done 3 complete drum kits this way. They ALL turned out great and tune just as easy & evenly as a new one. It isn't as precise as having it professionally re-cut, but it's cheap and very effective. The results are more than acceptable for most practical purposes. I have a DIY thread posted that shows how I do it.

Play the SONG......not the DRUMS!!!
"I think that feeling is a lot more important than technique. It's all very well doing a triple paradiddle - but who's going to know you've done it? If you play technically you sound like everybody else. It's being original that counts." ~ John Bonham
