RotarySMP:
I made the first chuck adaptor, this one for the 125mm Bison four jaw.

RotarySMP:
Made two more, one for the second three jaw, and a spare which I might use as a catch plate.

Ade's thread got me lusting for a camlock spindle again.

Last time I thought about making a D1-3 adapter for the Boley's threaded spindle nose, I thought I worked out that there is not enough meat in the D1-3 to fit over the threads.

Just to make sure, I modelled it this time. Buggar, I was right. Since the cams only turn less than 180° from unlocked to locked, I guess I could still get in there and relieve the end of the CAMs leaving the retention lip only in the arc where it is actually needed.

Then again, once we start getting unrealistic, there is also the Hembrug on Richardo.ch for 950 buy it now...

I was curious how much lower my tailstock is than center height. I turned up a brass slug to within 0.005mm of the 27.98mm tailstock ram diameter, and put a clock on it.

It is about 0.18mm (~7 thou) low when retracted, and quite level at about 0.03mm different along the length when fully extended when loose. It raises up 0.02mm when the ram lock is applied. Given the wear on the bed, this is not as bad as I feared. Sooner or later I'll have to have a shot at scrapping the bed.

It is still a nice old german machine. I was a single 1/100 over my finish cut to size that slug of brass, and at least on this lovely free cutting metal with a sharp HSS tool, taking another  cut of 0.005mm on radius over a short distance cut cleanly, and left a perfect surface finish.

I was showing my Boley fine feed adapter to a mate who also has a Boley 4L, and was embarassed how grimy it was. Time I gave it a thorough cleaning. It is in excellent condition, with no significant wear or damage.
