Clever Substitute for "Poor Man's Audio Deske" ?

I noticed that CDs are not the same diameter when using my De Mat.
The small lip on the outer edge of the dampening mat does not lay flat on larger diameter discs.
I am trying to find a way to cut, shave or sand the outer disc edge by carefully mounting the CD in say, a small cordless drill at low rpms. (self-centering device with rubber) ?
I'd use a junk CD to start, so yes, I already know the risk factors involved with scratching or trashing my collection.
I only need to remove very little material.
What I don't want to do, is spend $ 500.00 + on the System Deske.

I have been trimming my disks with the Audio Desk for three years. I have never had any problems with the 1000 cds and sacd I have trimmed.

I have a friend with a home solution for the Audio Desk. He uses his lathe, hardly a money saving solution for most of us.

The Audio Desk does not trim the disks to the same radius from center. It merely make the bottom half of the disk have a angle of 30 degrees I believe.
