Dan_ed, I feel the Alignment with Mintlp Tractor can be done in one sitting but a quite long one. I myself took about 1 hour 45 minutes before feeling confident that I'd never have to go back again. Insuring that I did indeed have exacting precise Spindle-Pivot Distance, and providing Yip with this info, I had eventually noted "absoilutely poifect" tracing of the Arc at both extremes, but this of course is only 1/2 the battle!
Then comes zenith angle adjustment, and of course, this then becomes another monkey wrench-fly in the ointment, as making any adjustments in this regard will-can skew your hard worked-on overhang. So, it's back, and forth, and I found I walked away, and came back to the Table a good 1/2 dozen times, took a break, took a deep breath, and then back again at it.
Of course there's no law that says "this is it", and of course, I'll agree with you Dan_ed, that all parameters-adjustments on a Table should be periodically checked.
Of course as has been brought up before, and Doug Deacon I believe commented about this, and that is the fine tuning of VTA, as some of you folks do like to do almost on a "per record basis".
By varying VTA, this will of course slightly alter Overhang, and possbly as well Zenith Angle to an extent. I haven't my Airy 3X to be quite so sensitive to altering VTA all the time. Mark
