Oh my, I've got a kit similar with that one a few years back and never got a chance to actually build the machine. Lack of time, proper tools and the necessary hardware (linear bearings and lead screws) made me postpone this to a latter date. I wanted to buy a kit (only the plywood chassis and hardware) from Rockliff in 2008 but I just arrived in Toronto and could not afford to spend the money at that time. So, if you actually build yours and think you can replicate the chassis for me (I'll buy the hardware from Rockliff) I'm interested.
Good luck with your projects!
