I have a dozen or so short Brown & Sharpe collets. These have no threads are tapers near one end witha section that looks like a nut goes over it for drawing down into the holder. They possibbly came from some kind of grinding fixture. Over all length is 1.815" width at expanded end of taper is 1.593. taper is 0.582 long and then there is a "barrel" to make up the rest of the length. The area I believe the nut goes over is 0.333 long with a 1.288" diameter. I am trying to find info to buy or make a mounting block to use these. I think they would be concidered light duty since they do not seem to grasp the work beyond the end of the taper. They have the number 11 stamped on the face 180 degrees from the size stapming.
Every time I try to go to Hardinge's site I get a warning from my anti-virus program saying there is a threat-Exploit Script Injection-360.....what is THAT all about?
