Hi Norm
I also have the unmitigated pleasure of moving a 500# surface plate, so I can place my Nikon 6D Autocollimator & stand onto the surface plate for robot calibration. Hernia maker is the proper descriptor of that stand.
If you have a mirror long enough to span the distance between both optical paths of the sextant, then your index and horizon mirror alignment should come out nearly perfect! Just be sure of mirror flatness and its a slam dunk.
Regards
Brad
66 pounds (30 KG), to be exact. I think I'm the only person in recorded history to have gotten a hernia from aligning a sextant.
