Gary was no stock on the motors at the time so I got them from ArcEuro. I think they are the same motors wherever you go.

I never measured the actual voltage at the motors, I soldered and shrink wrapped everything before I plugged it in. Not sure I want to measure it at the driver end either, I am a bit nervous about exploding voltmeters. I used fat wires with fat insulation, had to cut part of the wire core away before it would go in the driver connector. Overkill perhaps, but I don't expect much in the way of losses even on the long run to the Z so probably around 200VDC.

The drivers aren't cheap but as they plug straight in to the mains you save on the PSU, also you can be fairly sure you won't have to replace everything later due to a lack of volts at the motors like I did.

Not sure you can stiffen the column. I thought about concrete but the movements are so small, thermite? Also I can't be sure the flex is actually in the column, may be the whole thing bending, may be where the column joins the base where I shimmed it to cut square. It is practically impossible to measure.
