I do think that this and the hexaglide/triaglide solutions are more
realistic for the amateur. I have to say that although the
rotational method looks elegant I can't think of a way of doing it on
a real budget. You really want a rack around the circumference and a
motor with pinion on each of the rotating arms. Fairly normal
bearings in the middle and some sort of roller system to stop each of
the arms from flexing upwards or downwards.

The hard part would seem to be the ring shaped rack. Perhaps a
timing belt could be glued into the inside of a ring. That is
perhaps a little too much of a botch. Either that or you need a huge
planetary gearbox to take to pieces.

If it counts for anything, I'm up for it.

If the machine is there, the software will follow.
