Reinvigorating a Polaris mount
Posted 01 February 2014 - 11:49 AM
I just dug out my Polaris GEM yesterday, and I'd like to smooth out the bearings without taking it apart. Any ideas? I was think a light machine oil applied at strategic points and allowed to soak in, sort of like putting brake fluid on rusty bolts with a wick.

It troubles me greatly that a GEM of comparable value is so expensive today. And it troubles me that I can't find my AC drive corrector. Before I moved out here in '04 I went to Gary Hand and got the polar scope and an AC drive for this beast, and several adapters. I can't wait to use it.
Next big task is woodworking-new tripod legs. The single piece ones from the c4.5 are too short for a refractor. That will be a few hours in the garage.

I have the superb Vixen HAL 110 legs on mine, and this really ups the stability.
I also replaced the threaded counterweight shaft with a shaft from a parted out Meade LXD 55 so I could use standard counterweights.
I use this with my SV110ED and heavy binoviewers and a 12 lb counterweight and I had my doubts the mount was up to it, but in practic, it has worked really well!
I used to like the Alt-Az, but mine has a RA motor and I just love traking so much that I never use the Alt-Az mode, but it is nice to have it.
I do love the mount. My favorite GEM in many ways because it is the smallest and lightest GEM I own, and superb for refractors up to maybe the 120ED (would need HAL 130s for that though).
Anyway, it is one of the longest held peieces of gear that I own. Lots of things have come and gone over the decades, but the Polaris is still relevent for people that like tracking.

with a vixon shoe, now it's ready for my refractors up to 102mm
Sct up to 6" or my reflectors up to150mm . Stable and light but not that
easy to find if your looking, the c80's a good match.
