Tom,

last year I built a split ring mount with a large round plywood ring. The
bottom bearing is adjustable so the large ring's plane doesn't move when
the mount is turned in rightascension. The declination axis is adjustable
too so the axes can be made rectangular to each other.
If you like I can post some pictures on my website. I didn't do this yet
because this mount came out too havy to use it very often.

Best regards,
Martin Cibulski
