Shouldn't be a problem to sand it.

To amplify a bit on what I did:
My CP is 3/4" MDF. I first drilled a 2 1/8" (I think) hole through it, then I routered out an area as big as the Crystal Trackball PCB down to about 1/4"-3/8". I set the PCB in the routered out area, saw where the wheels were, and routered out grooves for them down to 1/8". Then I installed the PCB using nylon spacers as standoffs. The whole CP is covered with Lexan.
Frankly, I'm not too thrilled with the hole in the Lexan. I suppose I could work on it with a Dremel to smooth it out, but I'd rather find a good ring to put in it. PVC sounds like a good idea.

I investigated the speaker port idea I had 8).
And I think it may be just what you are all looking for.
the only limitation is that they only come in 2,3,and 4 inch dia. (so mounting depth of the ball would have to be appropriate (at least to make the ball tight around the ring, a little gap would not be too bad).
here is a link:

the depth could be cut accordingly(it's only abs plastic) and pretty damn cheap at $3 for the 3".

hmm that looks pretty good. the crystal ball is 2-1/4" so it wouldnt be able to pass through the 2" tube. actually thats probably good for the most reveal i could get. it'll be 1/4" bigger at the center of the ball... so i will lose about that much from the center to the top, thats really a minimal amount. good find!!! ;D
i think i will get 2 of them just in case of any errors. ;)
