Here is my solution Peter. I leveled the pier once with the eight 12mm bolts at the bottom of the pier. The uncluttered top gives me maximum travel before an equatorial flip is required. The tapered gussets minimise any resonance or ringing. The mount copes quite well with 20Kg refractors even in strong winds. I doubt if it would with a large newtonian 10" maybe 12" no way. The belt drives are far better than the usual spur gears.
