If you cannot find the source of the play, perhaps you might send the RA axis in for examination. Just contact the office and ask for a return authorization number. Roland Christen Astro-Physics Inc.

Thanks so much for the information! Just knowing that others have seen the issue and were able to fix it helps a lot.

Joe Thanks for the post - this is just what I was looking for. Tom M

Hi Tom, Based on personal experience, I suggest that you give Howard another call directly. You may have to leave a message, but he'll get back to you. You can also try to call back and get him

Ok. Understood. However I was not made aware of that. Having emails go into a black hole does nothing for a companies image.

Hi John, I haven't read the entire thread and Rolando is the expert. Here's what I did to remove the RA play with instructions from Rolando and Howard : main@ap-gto.groups.io | Advice needed: I

Hi Mike - you aren't butting in - any suggestion is appreciated. Unfortunatley the CW shaft is rock solid - not the source of the play. I checked that multiple times, and the play is sitll there even

I would use weather service sources for barometric pressure if it was not available on-site. Barometric pressure is going to be largely consistent across a wide geographic area. You can use the ASCOM

I am looking for a weather station to support the modeling of my Mach2. My candidates are 2: 1) Pegasus Astro Pocket Powerbox Advance. My favorite, it handles USB ports, power and dew heaters. And

I'm in the same boat. I talked to Howard on Sep 22. He told me he was knee-deep in a must-do project involving the keypad. Since I was not "dead in the water," he promised to call back once there

May I butt in to ask a basic question? QUESTION: Is the CW shaft screwed-in tightly? Put your fingers at the connection between the CW shaft and the housing. Can you feel movement? If so, the answer

Thanks for that detailed description - I found the parts as described, and when I moved the counterweight shaft, I could not see or feel any movement of the silver shaft. The counterweight arm does

Hi I had a talk with Howard about my mount and he asked me to send him the pempro curves which I did. I never heard back. It's now about 10 days. I sent a follow up and again I have heard

The Mach1 is an extremely simple mount. The RA axis has two bearings, one at the upper end of the RA body and one near the middle of the body. There is a sliding window on top of the RA body that can

Hi Roland, I went back and meticulously re-read your first post, and attempted to the best of my abilities to re-do everything that you suggested- just as you suggested, including the steps to

Yes, you can tighten the Mach1 with an Allen key. You can lock it up or tighten to any setting in between. Rolando

In ref to below - Just to confirm is Mach 1 considered a " New Mount " and as such it is acceptable to tighten clutch knobs with an Allen Wrench? tnx, Mike Ref: When talking about the

Before you do that, go back to my first post and do what I suggested. Then, with the lever half way up (90 degrees from fully locked), gently push on the counterweight shaft with 1 finger back and

Ok. Removed the cover for the worm. I did not feel any movement of the Worm when I moved the clutch assembly. So that does not appear to be the problem. On to the main bearing retainer nut...

Will do. Thanks!
