I'm working on an eyepiece box to fit my dob, similar to the one that Eric (erick) has on his SDM 12" dob, see the attached piccy. Lovely scope!
I have the box just about fitted out, and I have the stanchions(?) ready to go, now I need to find a source for the clamps/knobs to secure everything, six thereof.
Searching the net I'm getting some very expensive pricing!
Anybody know of a source for these at a reasonable price?

Preferably that I could by online?
Cheers

Chris
