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.
Rx8man: While not directly related to your question in terms of a "budget" Audio Desk alternative, i thought you might be interested in a couple of older posts of mine from AA on the subject. I've had mine for almost 5 years now with nary a problem from any of the discs that i've "circumsized".

The second link is from a thread where Jack Seaton mentions a friend that works for IBM testing various compounds / tweaks on CD and then testing for error rates afterwards. As mentioned, Jack and his buddy found that some treatments were detrimental and increased the error rates, yet he had no problems or second thoughts about using "the cutter" on his discs.

Various disc treatments and error rates

If you or someone else is interested, and much like i do with cable burning, if you send me your item and cover return shipping costs, i've got no problem with cutting some discs / burning cables. Those that are skeptics can experience the difference for themselves first hand for the cost of round-trip shipping. Sean

Hey thanks Sean, you're a super guy.
I've followed your threads closely on a lot of topics (tried to keep up) esp. on AC treatment.
I know there's another home-brewed solution for a cutter, I'm working on a simple method.
