I have made a slitting saw arbor and neglected to drill and tap a 3/8-16 hole in the back of the morse taper for the drawbar. After some careful consideration this was my solution. I mounted the drawbar in my boring bar holder and threaded the hole for the cap retainer onto it tight against the holder. (Lucky me I went 3/8-16 for the cap screw) I set the holder’s height and cross slide position by placing the taper in the spindle. It was a bit sketchy but I went slow and it worked out perfectly. I now have a very nice arbor with about +/- .00015 runout that will not accidentally come out of the spindle. A very challenging little project for a first real project but well worth the effort and a lot was learned.
