Hi John:

I have an interest in (and links to) the above hexapod. But also,
(under the pBreak link) some pictures of an experimental low-cost
hexapod actuator I've been working on.

Also for those who have been following my posts on inexpensive
hexapods (my last post concerning the socket-wrench type universal
adapter as a low-cost component), I'm happy to report I bought
a 1/2" universal drive and it seems to be just the ticket.

As the universal has a 1/2" male square at one end, six will
conveniently weld into holes in a circular plate tool platform.

The ballscrew/acme-screw will be ground down to 1/2" dia at the
lower end, and be inserted into (and welded) into the female end
of the universal.

The same sort of arrangement up above where the hexapod actuators
mount to the machine frame (with the complication that there is
a motor there which spins the 'spin tube') and effects the
extension/contraction of the actuator (by means of the nut
welded in the lower part of the spin tube through which the
fixed-against-rotation screw travels).

I'll post more info as I make progress (slow but sure).
