Back again,
Still working on the Dec assy of the GM200.
It's a real workhorse of a mount, but.....
I have found the 25T gear that meshes with the 75T dec shaft gear.
I have made several attempts at making a plate to hold the dec encoder.
I finally got one made that lets the gears mesh correctly, but....(there it is again)
The 25T gear is so small that I haven't been able to find one that is made to high enough standards, the center hole is never concentric with the gear diameter.
through about 120 deg of the gear rotation, it's fine. but the opposite 120 deg the teeth are loose enough that I'm always hunting N-S for my target. The 60 deg either side are so-so.
Does anyone out there have any parts or ideas?
Glen
