Hi all,
My Unimat WW drawbar measures, from threaded female end to the shoulder, 4.448"/113mm.
Cheers, James

WW collets are .275-40 threads. In metric that would be M7-1.0. That is the same for WW and Moseley collets.? Be careful because ebay sells what they call WW and they are Conoid. That is a swooping radius instead of a chamfer on the outside. The WW works on a conoid spindle but a conoid does not work on a WW spindle. I have conoid collets and they do not work on my Sherline.
I can measure my sherline drawbar.? Pretty sure its too short.
The Sherline collets alone are a good value.
Collets are on the way.
For me it is not clear how long the Sherline drawbar is.
Also the thread is not metric like the collets I bought.
