Recently inherited a Durden pacemaker combination unit and am trying to work out the horizontal borer. I appear to have the table and support post but don't know what other bits are missing (collet or chuck is definitely not there) Would appreciate any relevant info (photos , diagrams etc.) that anyone might have including thread size on the end of the shaft. by the way this appears to be a different model to the one that I've seen in the threads.DSCN0077.jpgDSCN0076.jpg
