How do you think the machine performs, and also performs being stretched out a little, I do not see anyproblems with anyone doing that, heck even the ones with the machine now can build another one larger and just take their time doing it.

Joe,
Once I get all the upgrades done I intend to map the lead screws. Then I expect that it will perform quite well. The Acme precision screws are something like .009 per foot or better, I should be able to map most of that out and could possibly get .001 per foot if I'm careful. Dumpster claims zero backlash (I'm still thinking of making my own though). I was thinking of making the bearing supports (motor end) out of something hard, delrin, possibly aluminum. This way I can really clamp in the AC bearings so there is no backlash their. More along the idea of mounting a ball screw. Might even be able to let the free end float in a bearing like most ball screws, rather than clamping it down with a spring.
But so far I still haven't cut anything bigger than 12X12 inches. Everything moves along the full lengths and I assume it will cut nicely along the full length too.
Powersupply pics this weekend I hope.
