It's a vcr/mouse hack that I found online. Credits go to axeman. Here are some pictures of how it's coming along. The flat piece is just something I had laying around the shop that wasn't going to be too hard to cut through or soft that it will break. I used this 3M 2 part compound to glue the flat piece to the vcr head. I didn't want to screw it because I wanted to lay flat on the bottom of the control panel. Need less to say I've used that compound on fuel tanks before for emergency purposes till a new one came in. So I know it's a strong bond after both surfaces are scuffed up a little.
The coupler is 1/4-20 which I drill out half of it just a hair bigger so I can press it on the shaft of the vcr head. On the other end I'm going to be using 1/4 inch threaded rod since 1/4 inch is the size of all the spinner knobs available to my knowledge. The knob I'm using is this which I'm getting from Mc Master Carr.

I had everything except knob $5.59 , couplers $3 and I got the encoder wheel printed for like $8 at a local shop. They printed 4 to a sheet. It was cheaper then buying or finding some transparent film. I forgot to mention I used hot glue to hold the cd center holder in place.
Here is the Axeman's site where I got the info from.
