Very nice, Marc! Looks solid as a rock.

Is that a 10" or 11" Byers drive? It will track like a Swiss watch.

Looks like the eyepiece height will be just about perfect when viewing at the zenith, and seated.

That thing is massive. And gorgeous. It will certainly be worth the time you've spent on it. There's no substitute for a good mount.

What are the shaft sizes? It makes that GPDX look like it wants a 60mm.....

Took the scope out last night inbeteen clouds. Nice and steady. One issue I knew would be a problem is stiction in the clutch. The later all nylon clutches have a lot of stiction. I have a 7" drive for the mount, but need to rebore the clutch to fit the shaft. The 10" drive is a bit bulky for this semi portable scope. The 7" is an earleir starmaster and has very little stiction. I could try some lube on the bigger drive. Have an electric dec adjuster in the works, and will convert the drive to a stepper or servo.

Thanks for the kudos  everyone.

So no pictures show up in posts like they used to? Am I the only one not seeing how to view pictures or is it a glitch of the new forum look that I just noticed today?

Yes the pictures have flown the coop. Maybe the fox had a good dinner.

I've been waiting for this thread to repopulate with pictures to see the Byers drive mounting.  Maybe you could post a few more pictures now to speed things up.

I'll repost pictures later this morning. Turns out I have a bit of a binding problem with the drive clutch. The part that clamps onto the shaft is too tight in the bore of the drive gear. The clutch assy is all nylon and changes dimensions with temperature and humidity.  It was a bit tight when received from Ed. Luckily I can take it to work and machine off a couple thousands.

Marc, I replied to you in the ATM forum on this, but was thinking that it might be the clutch faces.  A tight bore is an easier fix.  See what that does, first.

 

Barstow is a lot drier on average than South Carolina, that's for sure.

Yes, it takes time for the moisture to come out of the Nylon, bonds to the polymer.  The bore is part of the issue. it was 85 degrees the other nigth when i took the scope out.

The problem got worse the longer it was warm. Knew there was a problem when I backed the clutch screws off all the way and it was still locking up. It's all machined now and I added two more shaft clamping screws as not to distort the hub too much. It's clear tonight but I have plans. Maybe tomorrow.

I'll get more pictures together and explain a bit more about what I am doing. Going to use steppers with an arduino to control them. For variable drive rates and centering.  No GoTo crap. The ATM Forum is more appropriate for that discussion.

Can we get a few closeup pictures of the Byers drive and how it was mounted?  I have the same gear.

And yes, I too would like to see a couple of close-up pics of the drive and how it is attached as I have been considering a Byers 7" drive for my Meade #826 mount.
