Hi-
Here is one that was posted on Splitcoast a while back. I tried it and it worked beautifully!
You need two things to make it work:
A Flat Metal Washer-size 1/4"
CLock Quartz Movement for 1/4" thick surfaces (found at Mich*als)
The washer is needed because the hole on the CD is too big for the clock movement to fit. The washer makes the hole smaller and then you have a perfect fit!
I also bought a plate stand to set my clock up on my shelf, but there is a hole in the back of the Clock Movement to hang your masterpiece up on the wall!
