Looks good Jim.
I too am in what seems to be an infinitely long research, planning and design stage. I was also considering a similar gantry design. Are you planning on or done any deflection calculations? I would be interested in the results, could you post them?
I'm not familiar with the mechmate plans/designs. I have registered at MM, but have not looked around yet. What technique will you use to grind/mill the angle for the v-rollers to ride upon? When do you think building will start? Are you planning a build log? I'm very interested in your design and will surely track your progress.
Good luck and keep us posted on your progress.
Randy
