Where can I get a Digital Encoder kit for my dobPosted By Steve VanHyfte |
My dob is already built with a 1/2" azuimuth shaft. The top board has a 1 3/8" hole in it, and has a ball bearing. I have a complete Lumicon Computer/Encoders/Cables which I never installed, since the center bolt was smaller than 1/2". Lumicon is now out of business, Orion no longer sells the kits (or at least advertises they have them), JIM kits are at least $150 for a bunch of bolts, and Celestron No longer has kits for dobs. Astrosystems has a pivot kit, but again, it is a 3/8" shaft (too small). I need a T-bolt for the azimuth axis which is 1/2" in diameter, and has the 1/4" hole for the encoder shafts. Does anyone know where I can get one of these bolts off the shelf without having to pay the big bucks for a machined part.
