Brian,

Was the machine base basicly a hollow form made of steel, or cast iron?
What I'm trying to figure out is, if it would be possible to build a small
machine base out of 1/2" thick aluminum or steel plate, bolt it together,
and then have it machined to be square and true. Once everything is done,
fill it full of the polymer concrete, and bolt THK style rails to the frame.
Seems like if this could be done, we could come up with a design for the
group and have a bunch of the frame parts made and sold as a kit. Looks like
it would make a nice machine, Desktop size, maybe 8 X 12 working envelope.
It would look like this http://www.incrediblemachine.com/index.html

No idea what it would cost to have something like that done
