Brady: You beat me to it-I had a chat with Steve today and he filled me in on all of modifications. As he put it: "There isn't much shopbot left and soon there will be less." He has done a lot of what I was thinking about vis a vis the frame components but before I go quite that far (It's not the cost of the steel and welding, it's the overall time involved) I want to try some of the simpler things to stiffen it all up.
