Re: New G11 / Gemini 2 user with issues..
Hey there Chip.. Want to disassemble?? Absolutely not.. Too many questions of how tight, how loose, etc.. But I do love the design of the G11.. Elegant, yet simple, so I am not afraid to.. Especially

Re: Super greasy worm gears on my GM8
Fredrik, Is this a #492 digital drive GM8? I bought a demo GM8 with #492 digital drive looking for a lighter payload mount than my G11 for driveway duty on a JMI Wheely Bar and lighter payloads for

Re: New G11 / Gemini 2 user with issues..
Hi Derek, Hmm, it sounds like you may have damaged a gearbox. The older gearboxes used soft plastic studs that were heated and pressed to form a bad rivet which retained the plate which supported

Re: Mount Clutch Tensions
Hi Rodney, Ideally you want to snug the clutch knobs up just enough to hold and no more but it really makes about zero difference to the servomotors. Obviously there will be a very small additional

Re: Mount Clutch Tensions
First, you should shoot for good balance of the load and then introduce a slight eastward bias. Clutch tight enough so that there is no slippage during imaging or slewing. Tom

Re: Mount Clutch Tensions
Never tighten more than the minimum required to prevent slippage. Doing so dramatically increases drag due to (unnecessary) loading of the thrust bearings. Good Luck ! Jeff

Re: Mount Clutch Tensions
That is my goal as well Brian, but I was just wondering how tight these clutches should be for all of the different modes, GOTO, tracking, etc... I had them really tight when i was learning this

Re: Mount Clutch Tensions
I just have a push-to GM-8, and a lot of times I'll reach down to loosen the clutch to go to another object and find them already "loose". I don't have to tighten mine much at all with C8's or an

Re: Mount Clutch Tensions

Mount Clutch Tensions
Tonight I will have this G11 out for the first time. I've had a few dry runs in the house just to become familiar with the working parts of the mount and Gemini 2 HC. My question. How tight should the

Re: Super greasy worm gears on my GM8
Heh, that's good to hear! I was hesitant to buy it at first since it was still just outside my budget for a mount that's 20 or so years old. I realized that most of the mount will stay the same

Re: New G11 / Gemini 2 user with issues..
The sound in the video sounds a bit "plastic-y" instead of metallic which leads me to think it could be the gearbox. Hard to tell with the audio. Swapping motors might be informative, and/or

+1 on Chip's advice... I actually prefer older Losmandy mounts. Usually if they are working well, they keep working well. I always look for wear on the anodizing of the worm wheels, if they are well
