My first thought was a wood block although wood dust and lube oil are a
bad mix. You can see cuttings flying away on the last pass along the
back side.

This machine is owned by the University of Stuttgart and is a part of
experimental work at the Institute for ControlEngineering of Machine
Tools and Manufacturing Units ( http://www.isw.uni-stuttgart.de ). Till
said that he was very busy with calibration of the unit and would try to
write up something soon.

He also said that he was building a small one at home. I have one son
that lives nearby. I'm going to twist his arm to visit and give me a
report which I'll put in the linux dropbox. There is a very crude start
of an EMC hexapod index page at

www.linuxcnc.org/handbook/part1/principles/stewart.html

BTW - NIST and Sandia also have similar monstors and G&L showed a
prototype at IMTS a few years ago.
