H:
I'm looking for a machining shop or hardware store in Singapore where if I give the diameter and threading specs of the polar axis shaft of my GP mount, they can make/provide a tube of at least 8 to 10 inches long. A PVC tube will also be ok.
I plan to use that to screw on to the polar axis shaft (instead of buying a polar scope) and grab on to the RA encoder shaft.
If you know of any such shop....would appreciate it if you can let me know.
Thanks much.
