The biggest hurdles are fastening & aligning the nut brackets to the
underside of the table and the saddle. (Separate brackets required...) The
saddle in particular was awkward to move around, due to its' size & weight.

I went with a bridgeport bracket split in half the first time, but had to
fabricate a right angle weldment for the Y axis to get enough stiffness.

On the knee, I removed the cylinder mount extension casting and worked from
the knee casting flat face to mount the 'Y'.

A manual screw type clamps the knee. The Y axis clamp is hydraulic, and
works by pressing thin flex plates against the ways. (underside of the
saddle, integral with the metal keeper plates)

The clamp cylinders are flat discs about 1" in diameter, 0.100 thick. I
think the X axis clamp, at least, had 0.375" dia bosses that are what
actually contact the metal strip.

The 'X' clamping distance is only 24" or so, so I took it off to keep the
metal strip from catching on the cylinders inside the clamp, among other
things.
