Re: Balancing the declination axis
I drilled holes as close to the center of the mounting plate as the
ribbing would permit and now the balance is much much better. I
still need a few pounds at the front to balance things but this is
much better than the 30 I had before.
Thanks for your help.

can you get one or two Vice Grips or C-Clamps to fix the rear OTAring to the
plate temporarily, and see if it helps the balancing act. That wayyou aren't
committed to more holes and making Swiss cheese out of the plate.The front
ring will still provide solid support as you test the "optimumposition" of
the temporarily sliding rear OTA ring position.the plate,
