I have been looking for a way to build an inexpensive but rugged equatorial mount for a 63" long 30 lb. refractor. I stumbled across something called a "dividing head" in an old Enco catalog. This appears to have a 40:1 worm gear with clutch and heavy bearings and can be tilted from 0-90 degrees for $335. The thing weighs 38 lbs. Adding some declination bearings and a counterweight should complete the job. My question..Am I way off base here? Any guesses wether the worm gear will have a bunch of slop? Would the worm gear bearings be too stressed? All comments appreciated. Dave S.
