Once I got the frame together this is what it looked like. The red bearings were problematic as the outside diameter is 7/8" and I could not find anything that fit them. That is about 22 mm diameter. There are some 22 mm clamps that are used on Drones but they are wimpy as they were not designed for use on a CNC machine.

The new Z axis is only four inches wide. This next picture shows the new Z axis in front of the old six inch wide Z axis.

1. A 10-32 screw fits the T slot nuts.
2. A 10-32 Truss head screw head fits the T slots.
3. A standard 10-32 nut, once filed slightly, fits the T slots.
Here is my current state of construction:
