Brian you have helped me. You were a huge help with PHD2 and I thank you. Even for doing imaging of planets the guiding feature of sharp cap goes in E/W and South without a problem. But north is a

Dear Occativ43, The DEC on the GM811 has 180 teeth to it's ring gear. The RA has 360 teeth to it's ring gear. If the worm is in contact with the ring gear, the DEC should move faster, per worm

It sounds like you are experiencing DEC backlash, which is a normal thing on this mount the question for you is: is it a manageable amount of DEC backlash? for visual, you can increase the TVC value

I have a one year old Losmandy G 8 11. The DEC moving North on the 1st command through any interface remains a persistent and vexing problem. I am hoping someone might have the same issue and a

Yes. I polish the OD of the far R4 bearing by hand. I rub the bearing outer flat section in the circular direction of the circumference, that mates inside the block cylinder. I use smaller and smaller

The bearing damage would not need to be fatal to have an impact. In fact it could be very minor. Did you look at the Wikepedia link to brinelling that I posted? I have seen bicycle headset bearings

Anthony looking back on this comment, many people shoot at longer focal lengths using the G11. It’s rated for what, 60lb? so you aren’t going to get a giant telescope on there. But I’ve imaged

Michael, I know you recommend 200 grit sand paper, but what is your methodology for applying this? How are you actually doing the polishing mechanically?

Hello group.? I understand the complexity of this design and Scott not wanting us to put a wrench to the SLW.? Am I wrong by "assuming" a guy would need to take these items apart anyway for the

If you watch the recently posted videos from Losmandy, the adjustment of the SLW is explained. I have been experimenting with very slightly tighter and looser settings on that bolt. If it is set too

Having just done a handful of these adjustments at Losmandy shop (practice), your experience of the SLW doesn’t sound right. It sounds like it was way out of adjustment. Was this Daniel’s mount?

Gotcha, Anthony. When I took apart another owners SLW, I was surprised at how hard it was to turn the inner transfer gear the is attached to it's Oldham coupler (with the gearbox loose so the motor

Michael- Most of what you are saying jives with my thinking, and in fact the loading of the fixed outer race makes more sense to me than the original orientation, because of the potential for friction

Hi gang, Sorry ... I've been on a long vacation, which was an amazing trip through some national parks. I'm in LA today and getting finally home tonight. I've read Anthony's noted and the others. To

These bearings are designed for high-speeds and radial loads. It does not take a high axial load to damage one. This could be occasional peak loads, and might even be exacerbated if the worm was

Hmm, Anthony you are missing the point, these bearings have been used on this and many mounts for decades with excellent results and long life. The reason is that they turn so slowly and are under

I am getting all of the reasons explaining the current thoughts on this, but I wish someone would explore my theory with me. These tiny bearings do not deal with axial loads well at all. I looked up

Derek i agree for two-piece worm blocks the belleville seems like a good idea. After watching the latest spring loaded worm adjustment video and reflecting on my own experiences working with it, i am

OR! Just flip your black arrows so they point to the left and that would be the simplest "point" of the matter.. The Belleville spring washer helps ensure the worm contacts the inner race of the left

I think you are over thinking it.. The *ONLY* consideration is shown by the big blue double ended arrow in your first image.. Which is scrambled but I think it says "Worm lateral movement possible"..
