Well went the other way. Took the belt sander out, put in my vice upside down. Marked the edges I needed to reduce to get clearence on the hand guards, which was not much asked several people and they said they could not even tell that it had been modified. Used 100 grit on the belt sander, finished by hand sanding with 400 grit.
Note: Do not use and orbital or a "Block" to put your sanding paper in. This can cause small cracks around the edges. This was taken care of by going back with the belt sander. But some reason one of the aforemention methods did not work. The belt sander and hand sanding, almost looks like a factory finish, you just have to be careful and try to make both sides look symetrical.
