I’m going to try that out since it seems fairly easy to do, all I need is the hole saw. I’m tired of drums and been wanting to convert to disc brakes so it seems like I can get by for now with this method. Shotgun.
It's easy to do especially with a drill press. Takes less than 5 minutes a hub. You can do it with a hand drill, too, you just have to be careful and keep the drill as straight as possible. The way I do it, I just always drill through the swedges all the way through the drum until I hit the hub. That way you know you have cut the swedges completely off.
