that this hasn't been done in the hobbyist world. After all, what most
folks rehabilitating drives are interested in is radial alignment. I
doubt that many know how to adjust azimuth.
Well, for the SA400, radial alignment is/was an issue.
For the other positioning mechanisms, radial alignment was less of an
issue, and azimuth and even motor speed were more common problems.
