I will be using 1/2-10 2 start acme screws on the x and y axis. Enclosures for the belt drives will be one of the first things the machine cuts.
I have yet to design the A-axis but I have 10 inches of clearance below the y-axis carriage and a total of 7-inches of Z-axis movement. When I design the A-axis I will post some pics of it, but the building of the base machine will come first. If you want to see aproximatly what I am going to do look
here at Lionclaw LC-50B
I am not sure if I can build the machine stiff enough for 10 inches of clearance, that is why there are so many holes at the top of the gantry sides. All flat surfaces of the machine will be laminated with Counter top laminate like spalm's machine is, as seen
here. I will be drilling all those holes so that if I have to reduce the height of the Y-axis I can just move it down without having to rework anything.
Thanks for the response.
