  1. I put valve grinding compound on the joints and screwed/unscrewed them until I was able to get 3+ more rotations on them. The joint is a little loose but with weight and grease afterwards it is very stable. Its easy to tell if you are flipping in the same direction to much as the joint gets sloppy. It is immensely easy to point and I tested tracking on a few random stars and it works perfectly for viewing. No wobble from the breeze in the slightest which was my main reason for this endeavor. It is stable when snugged down as the system rotates so freely BUT I see you need to rotate the OTA so the eyepiece is more convenient as you track. I am going to bandsaw up a pair of curves that will clamp the tube in place and parallel but be loose enough to allow rotation.
  2. Well I needed a better mount but do not have any money to spare so I spend $11 at the home center and came up with this. Its only 3/4" pipe but the telescope is also only 3lbs. I filled the tripod legs with paving sand and that made the tripod from 1lb to 8lbs. I lapped the threads on the polar and dec axis an extra 4 turns so they move very easily. Hopefully clear skies before bed tonight and I can give it a try!
  3. Im thinking of making a GEM mount out of cast iron plumbing pipe fittings after seeing this picture. Should be very affordable and I could fill the 2" base with sand for extra stability.
  4. My scope has one of these fantastic mounts. It makes pointing very difficult as the "fine adjustment" threads are so loose everything wobbles around in the slightest breeze. The pivot is also just a fork screwed onto a bolt without bearings so if you unscrew it enough to rotate you then get more wobble.... Is there anything you guys would do to make this more useable? Or should I just scrap it and make a dobsonian style AltAz mount?
