El telescopio no tiene marca, es fabricado por mi 300mm f / 4, con anillas parallax y milano losmandy 44cm. Mi otro telescopio es un C11 celestron.

Hello Michael, Thanks for your thoughts. I guess I will just have to try a few polished bearings and see how they slide with decreasing ODs. Once I get one that easily moveable, I should put it the

Nice work John to take Stuart's idea and run with it. I don't know how much OD of the bearing should be undersize of the ID of the block, at room temp. I was only requiring that it slide under the

Very deep writeup, Alan...you innovated a number of things to elucidate the issues. (Good comments by Henk about "stuttering" also but I have a suggestion for that below). Thanks for describing your

David, With many members on this forum, the mount they choose for larger SCTs, like 11" or 14", is the Titan mount. For a Newtonian design, you have a large optical tube with large external

About the asymmetry that you mentioned where the worm is lifted going one way and pulled in going the other way:? I noticed with my system that the weight of the focuser with imager and guide scope

They do seem to rhyme. but I think that it's a different song:) The one set of data that I attached, I had balanced everything pretty well, but this has been going on for days, and I know for sure

Hello folks, I have one of the new GM811 with the "spring-loaded" worms and tucked motors.? In this thread I will mention some of the testing I did and a few things I learned about backlash in this

That was with "DIY spring loaded worms v2" where only the outer block was floating so in the case of radial motion the inner block bearing would become misaligned.? My thinking (for v3) was that by

Oh, ok.? It's because you wrote this earlier: "Also, my outer block bearings should realign themselves because mine float and are pressed by a tangential spring.? So I think the inner block needs

The only self-alignment of the worm assembly is in the gear plane, radially towards the axis.? There is no tilt alignment.? If by tilt you mean a vertical motion in the direction of the gear axis,

Hi Users, I have an old Losmandy G11 with the two separate blocks and have consistently had issues aligning. I do not have the OPW block nor the spring loaded worm. It is a 492 control. I would

David, The pdf is on the right column, the HTML documents are on the left. You need the 'G-11 EQUATORIAL MOUNT <http://www.losmandy.com/pdf/g-11-manual.pdf>’ document. Paul

I don't see where this design allows for tilt self-alignment of the worm blocks

Good idea Alan, thank you.? I will hold off on the Belleville washers for now since I just changed my DIY spring loading such that the blocks and bearings should be aligned properly (see my other

Yes - purposely set the blocks so that there is too much axial play in the worm. Bias east heavy to test the right block, west heavy to test the left block

After seeing the 76 second cycle in my guiding most likely due to misaligned bearings (G11S two block worm) I decided to tighten the blocks on to the cover like a single piece worm block to get the

I agree with Paul but Keith brought up an interesting point and I assumed the LAT/LONG/TIME could be set from the PC Gemini? interface but it appears it cannot.? Leaning more toward what Keith wrote
