There have been a couple new members looking for a good way to profile sand rims to match top and back domes without buying or making sanding bowls. This is the method I use in the beginning. It is a sanding bar made of 1 x material with wedged ends to replicate the bevel. It is simple and cheap. You must move you pivot point in the oposite ditection you progress your sanding. This will match very close to a 15' back dome and a 25' top dome. You will want to adjust the bevels to the slope of the domes you use.
