Folks,
Two questions, I have a lxd-55 motor set mounted to a CG-5:
1) How is the AZ and Dec ratio calculated in Autostar? The LXD-55
has 35 tooth gear on the drive, 37 tooth gear on the worm. I have
a 40 tooth gear on the the worm. I'm assuming that I can multiply the standard ratios (2.3715) times 40/37 and end up with the correct ratio?
2) Has anyone tried to fit thrust bearings on the worm shaft? It has
~6mm diameter shaft and I found some thrust bearings of various inner and outer diameters at www.vxb.com from the R/C car industry. Itlooks like I could fit one easily and cure some of the backlash problems inherent in the CG-5 worm design.
