Yes, 7-3/8" in the Y direction. By the way, I was reading some info about the Rong Fu mill drill (also sold under Enco, Harbor Freight, and many other names) and learned how to tighten the gibs and the bed nuts. Got my lash down to .25 mm (mine's metric) and movement in the table down to about .002". Then I read an interesting conversion to full CNC using ball screws, stepper motors, and an available computer program. Fascinating stuff for an old mill drill.
The alignment issue in the Z direction I was referring to was when you run out of travel and need to install a longer drill, for example. Only way to move the spindle up on the round column messes up alignment. Only way I know is to leave in the smaller drill inserted into the previously drilled hole, raise the spindle and lock it with the drill in the hole. Then raise the quill which allows you to put in a longer drill or whatever. Just a pain.
You mentioned you put a stepper motor on the Z axis. Did you convert to ball screw? How does the stepper motor prevent the quill from pushing up while milling or do you depend on the quill lock?
Good to hear you're not expecting any more snow. I may be passing your exit Saturday afternoon.
