After the recent distraction caused by the 3D scanner, resurrecting the 3D printer and buggering about with the throttle bodies for my Honda S800 engine, the spindle nose adaptor has seen no action.
On the face of it, there should be little more left than to assemble the parts and test the runout. The big, big question is - is the runout remotely acceptable? I will be more than just slightly pissed off if there's any noticeable runout after all the time and care I've put into this thing.
Last time round, I was preparing to finish machine the taper and face while mounted in place on the lathe spindle. Here's what happened.

There. Job done. Good tight fit on the taper and no cockups along the way.
What about the runout?
The next (final?) step is to do the final assembly and check the runout. Firstly, the grubs screws that hold the cams need to be ground back a little. Skimming 0.6mm off the face of the adaptor has made them stick out slightly proud of the adap[tor body so that the chuck can't sit flush. A quick spell on the belt sand does the trick
