Greg, I was thinking 2 foot + sections could be added and removed when not required to save space, it's not the type of machine that you or I would use on a daily basis.
I also toyed with the idea of using lengths of timing belt in place of gear rack but the rack could be more precisely anchored to the "add on" sections I mentioned.
Darren has a point in "The thinner the material the faster the speed of cut required."
