[COLOR="Purple"]To try and stiffen my single upper ring, I'm adding a second ring. The dowels are inserted into holes in each ring about 1/4" deep. This seems to make for a very stiff structure, even before the dowels are glued. Original ring (bottom) is 3/4" plywood. New ring (top) is 3/8" plywood.
The price to pay is an added pound of weight hanging way out on the truss poles. That may be okay as I'm a little back heavy right now. Once this is all done, I'll adjust the alt bearings placement for best balance.
I'll post another pic once I glue it up and reinstall the spider and focuser.
