I start with a fixture plate mounted in the CNC.




Pick up the center of the plate w/ a Dial Indicator to find a zero point. I use CAD to draw up a bolt pattern to use toe clamps to hold the frame down. The ADV frames weigh about 24lb, and I can only hold onto the head. My machine is not large enough to secure the entire frame inside the machine. Fingers crossed......hope this works.



The bearings (top and bottom) are 2 differant sizes on the ADV, so I turned a couple adaptors that I can swap out when I flip the frame over. These adaptors fit into the base plate and locate the head tube so it won't move when cutting it.
