I am in the building stage of a CNC rotary axis routing lathe based on the OX CNC Router. My Roto-OX machine will use the X-Axis from the OX CNC router modified to use 20X80 V-Slot instead of 20X60 as I am building the machine 1500mm long. The Z-Axis will use the extended Z-Axis wheel plate recently added to the OX drawings also modified to accept the 20X80 V-Slot rail. I have a Chinese stepper spindle and tailstock which will operate the rotary axis. I am using the TinyG controller board on the Roto-OX. I have posted some preliminary Sketchup drawings of what I am building but am tweaking the design as I go so things will likely change. Check the discussions section to see my latest progress.
