Hey Tony,
“X-50” does not designate a specific model, but the diameter in mm of the hollow chrome-plated, induction-hardened steel linear motion shafts of the X axis (Differences Between X-50 and X-35). Do you have ordered a Journeyman (48"x32" Cut Area) or a Woodworker X-50 (32"x32" Cut Area)?
The footprint of Woodworker model is in the Onefinity Owner’s manual (to be found on the Support page) on page 15. This gives you the depth of Journeyman and Woodworker which is identical for both models. As for the width, which is the dimensions in which both machines differ, you find it in All Machine Specs.
Unfortunately, you will not find every dimension you may need, e.g. for the outer distance of the machine’s feet. For this, it useful to know this:
Did you also buy a QCW frame (Journeyman, Woodworker), (QCW Frame Manual (to be found on the Support page))?
This forum is full of people who use vertical clamping and presented their own solutions. I watched these efforts regarding vertical workholding with admiring enthusiasm. I found many of these implementations very impressive:
I personnally like Robert’s vertical clamping vise because of the vise clamping.
Welcome to the forum!
