How to you go about protecting the bearing area, for the grit and stuff?

I've used tape before to protect an area from the blaster. duct tape works well, but can leave a sticky residue. electical tape doesn't leave as much residue, but it's also not as sticky.

anything soft that the media will bounce off of will work, especially if you take care and not aim the nozzle at it.

sounds like a plan, blast them it is! I thought I read on here once where someone blasted some rotors and 5 or 6 folks responded saying that it was a big no no, and that they'd never use rotors that were sand blasted.

I guess if I ask again next week, I'll get 10 people saying they did it once and ruined their rotors


allwell. I'll blast the hub of these and let the machine shop turn them to take care of the rest
