I am slowly working thew this project I decided to do it because there are shapes I haven't done before such as the A frames and the girders that wrap around to hold the parallel motion. First i have to convert to metric and then to 80% and redraw it. I scratch built the A frames and the Beam and cylinder with Pedestal O.K but it is the girders that are proving tricky were they screw to the A frame as there is no room to get a spanner in, I could use a slotted screw but it doesn't feel right. Any way I just thought i would show work so far.
