Henk, I do not believe that this will help you for the reason that the tightening of the clutch creates a variable *fore-aft force* on the ring gear due to the the axis shaft being off center. This

Michael, I've said a lot about have to minimizes periodic errors from? the gearboxes and the worm assembly in the past month, and how to and improve Dec guiding performance through using smaller step

I don't see how one could preload the RA bearings with all the weight on it.? Can you be more specific and point out what could reasonably be done while keeping the system simple?? Preloading these

Looking for one Losmandy High Torque motor. This is for a Titan mount but I've been told that they are the same motor as the G11. Also looking for either a Gemini 1 or 2 controller at a reasonable

Over the past few weeks while following the discussions here in the user group and tearing down and servicing my recently acquired G-11 I'm learning that there are some fundamental design issues that

There is a serial number at the bottom of the RA axis. The company must have a way of deciphering that into the mfg date. I think the first 2 digits after the initials HGM indicate the year of

Hi Henk I'll try and address your questions The touch points don't change by balancing the scope. The total mass of the DEC axis, telescope and counterweight system is supported by the RA shaft and

I may be able to call in to get the date of manufacture of my G11 but it has a black ring gear and is a gem-1 with the last version of the hardware. Standard un-tucked motors. I'll confirm the worm

I suspect that you've got things too tight so there is binding going on. i suggest you loosen the connections at the coupler, the gear reduction mounts, housing and the bearing blocks so there is some

All great ideas. Actually, my thinking is that most of the slop in the RA shaft is taken up when the thrust bearings are loaded as the clutch is tightened, at least i

I think my takeaway from these studies is: The factory changed designs and materials during the years of production. It may change again at any time. Peter on his older G11 system and me looking at a

So the G11 axis has a radial bearing surface for the ring gear mechanism after all?? Well, never mind what I said, then.

Jim can you share your guidelogs or PE analysis data files? -- Brian Brian

Hi gang, I want to correct something. That is, whether the ring gear has its own cylindrical needle bearing or not. It turns out that the G11 has one and the GM8 does not. The removal of the

Don't the "touch points" as per Peter's drawing, depend on how the scope is balanced? If the scope is balanced towards the counterweight, these touch points would be just opposite.? And if the

I purchased the one piece worm from Losmandy hoping to get rid of some of my errors. So far my 76 sec is worse than ever, and my PHD2 rms got worse. I snugged the bolts for the worm block to worm

The spring washer should be able to be smoothed easily. You will need them to be able to moderate the clutch pressure. As others have noted with the RA shaft since there must be some clearance there

Michael, the shaft and the round plate on its end are definitely aluminum. Its weight is inconsistent with a different material i.e. stainless steel. The areas with wearing signs (discolored) are

Even though I have never taken off the ring gear assembly (no reason to so far), I think I know what's going on here. The problem is that the ring gear assembly is not sufficiently radially
