RE: [CAD_CAM_EDM_DRO] Z axis on the knee, how practical????

Bridgett does not care if I lean on the table while she works. For that
matter she doesn't care if I jump up and dance on the table as long as I
have the air assist on. Just moves to where she is suppose to go. My
Shoptask is a driven quill so I have experience with both. The knee
moves plenty fast, but it is not a problem, but something different to
get used to.

http://groups.yahoo.com/group/jobshophomeshop I consider this as a
sister site to the CCED group, as many of the same members are there,
for OT subjects, that are not allowed on the CCED list.
