Trial fitting of the adaptor body to the Tree spindle nose reveals a problemette - the adaptor bottoms out on the taper nose before it seats on the actual taper. The nose seems to be longer than the taper bore.
- What's the problem here?
- Why have I only just found out?
- What can I do to resolve it?
The reason I haven't spotted it until now is due to the fact that I machined the adaptor taper on the Tree with the Vertex 4-jaw fitted to the spindle. I have avoided disturbing the chuck until the last possible moment. So it's only now that I have removed the Vertex chuck that I am able to do a test fit. And my CAD model was created from the BS ISO standard, not measurements taken from the machine. Doh.
