I think anybody can measure the clutch bearing clearance in the mount using Plastigauge and It should be close enough to know if there is a problem or not. Using Plastigage has the advantage of

I hear ya on the AP mount Eric. but lucky for me ($) I'm a natural born tinkerer - Ha! So Losmandy is perfect. Regarding the hammer, it helped in my case but I still have a .003" out of parallel

I bead blasted the clutch surfaces of one of my G11's. It did indeed grip well, at the expense of more difficult balancing. The mount was used for astrophotography (30 minute subs). The clutch held

BTW, FWIW, this is definitely not the approach I would take to remedy the noted problem ! -Jeff

CWD == CounterWeight Down Dave

Counter Weight Down

I have the phone app, haven't tried it yet...Uh, what is CWD? Rodney

Like Les stated, for visual use, level is not critical and the NCP is a bit away from Polaris. I used to use a phone app called Polar Finder that shows where the NCP is relative to Polaris for your

Set the scope up in the bedroom and leveled. Put a weighted string down it. this is what I have. Once i do this outside, then zero in on Polaris, and do the two-star alignment, I'm assuming I'm good

I'm looking at those now Jeff. Think i will have to get one...The way your eyeball moves around the sight hole, it's hard to say when it is centered. Good point. Rod

Leveling the mount isn’t really critical. Then get the RA axis pointed at the north celestial pole by using the altitude and azimuth adjustments, regardless of what method you’re using for the

Yes. Rodney, when you say RA hole, does your mount have a Polar Alignment Scope (w/ reticle) in the hole? If not, your attempts will be very crude at best. And, you are correct, next time use the Alt

Yes Brendan, Al on Al will gall quickly given half a chance (even if it's hard anodized). I also recall burnishing the threads and deburing the thread holes on the ID when I got a set of knobed knobs

Finally had a clear night here in the Florida panhandle so I took the scope out and set it up here in the apartment perimeter on an asphalt road...Think I made a boo-boo during my setup... First thing

The orthogonality of axes and parallelism of clutch surfaces has been done before http://helixgate.net/g11.html. ( Michael Siniscalchi ). My guess the clutch has a purposes there must be some tension

Say what?? Did I miss something somewhere?? Derek _____ Sent: Friday, October 13, 2017 3:48 PM To: Losmandy_users@... Subject: [Losmandy_users] Re: New G11 / Gemini 2 user with issues..

I'm getting the feeling (maybe a little late- hehe) that there are a whole lot of Losmandy mounts with potential axis to thrust bearing face alignment issues. (meaning thrust bearing face to axis

With that I agree Chip, and I may look into a set of those pads just out of curiosity as my own out of square issue persists despite my best efforts. Jeff

I think we are all under too much pressure! We must stop beating ourselves up... there is certainly a design issue with the plastic clutch disks. They slip for a variety of reasons: 1. the plastic is

Hi Tom, They are out there if you look on some of the European sites and there are several US web pages with these issues too but usually they are resolved by returning the worm to Ovision and getting
