Re: Losmandy GM-8: Anomalous wearing of R.A. shaft
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

Re: Losmandy GM-8: Anomalous wearing of R.A. shaft
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

Re: Relationship between needle bearing wobble and variable worm mesh and backlash
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

Re: Relationship between needle bearing wobble and variable worm mesh and backlash
Michael B., That is interesting about using half the ring gear. When did a total tear down, clean and relube last year I did not mark orientation of either the RA or the Dec gears. So the new

Thanks all!, Just spoke with Losmandy yesterday. Seems there are some issues with LW tripod parts holding up some orders. Figures...? ?Looking forward to the new mount.? There is penty of good

Re: What result I can get with the current OPW in my old G11?
When you replace the worms you might want to consider running the worm gear 180 degrees to CWU position, then releasing the clutch and moving your Dec axis back to CWD. This puts you in the "unworn"

Re: Relationship between needle bearing wobble and variable worm mesh and backlash
Under normal operation if the clutch is never released and the relationship between the worm gear and CWD is maintained all the wear on the worm gear occurs on only one side over some portion less

Re: Losmandy GM-8: Anomalous wearing of R.A. shaft
It can be that the RA axis shaft has just lapped in to true roundness. I notice that some of this is in the area of the thrust bearing as well. Is it smooth or is it scored? I'd only be concerned if

Michael, thank you for the helpful tips and for indicating the source of possibly better replacement parts in Europe. Sandro

Re: Losmandy GM-8: Anomalous wearing of R.A. shaft
Sandro, No idea exactly what caused your steel shaft discoloration, but it cannot be anodization. The shaft is steel. It may have been hardened and appears darker color. It seems simply polished where

Re: Losmandy GM-8: Anomalous wearing of R.A. shaft
Sandro, It is surprising that anodizing was used on a moving part, as wear would eventually remove the coating over time. In present day mounts, I think these shafts are all stainless steel. The

Losmandy GM-8: Anomalous wearing of R.A. shaft
Hello everybody, I have a GM-8 that I purchased new in 2000, which I have not used heavily; so it is still quite new and behaving. Lately I noticed that the clutches tended to slip, probably due to

Re: Runaway slew while using PHD2
John, Brian - Wait until release 1.11 goes to beta then test drive the SW again. Yes - things are being moved around, new stuff added and old stuff tweaked.? Its difficult to keep up at times.

Hey Jim, At the time I tried, there was no Framing and Mozaic Wizard, which I really like to use in SGPro. You type in the object name, e.g. NGC 6888, and it brings up a wide field low res image of
