Here is where I got my material to mount my degree circle to:
Laminiated (~$6 at Staples) and mounted:
Outside cut (using only the tools you see here):
Inside cut out:
Its a fit!
On the mount:
My "pointer" (a red LED from a broken mouse):
My power source (3 AAA batteries): http://i276.photobuc...zpsd1c68416.jpg http://i276.photobuc...zps5c60c821.jpg
The switch (someday when I am brave enough to make permanent changes to my telescope, I will drill a hole and have this screwed into the base.) http://i276.photobuc...zpscbe5f6d9.jpg
FYI: I got the batter pack free from http://www.keyelco.com/

The degree circle rotates by hand. Surprisingly it doesn't really move when I just spin the base. Regardless I think I still need a "locking mechanism", but I need to rethink my idea for it. I had this spring loaded thing in mind, but it doesn't seem to stop it spinning. I need to find some kind of knob/screw that can fit tightly on a small L bracket. Anyone know of anything I can get at Home Depot or similar store that would work? Something like this: http://i276.photobuc...zpsa1544a66.jpgEDIT:
I was searching on Home Depot's website and found some possibilities for my locking issue...how about a...door lock!http://www.homedepot...r-Lock-S-402...http://www.homedepot...olt-Lock-S-4...http://www.homedepot...o-Door-Lock-...
I'll have to stop by the store and see if any of these or things like them will work...
