Thanks for the code. I'll print it out and study it. I figured there had to be a easier (and shorter) solution, but since I'm only just starting out, I don't know enough to make the code better (yet). I did this mostly as a learning tool; one that I'll revisit time and again.

Update:
I took your advice (and grinder's) and reworked the code. I forgot to bring the disk with me today, but it is much smaller now. Thanks.
