the drive pin that prevents the quill from rotating in my tailstock has been getting aggravatingly looser and looser.
Time was when a tap of a hammer would keep the tapered pin in place for months at a time
but it eventually got to the point of having to use a snap clamp to hold it in place but that would slip off the rounded surfaces
today I decided it ends now.
i removed the tail stock and laid it on its side drilled and tapped for 3/8-16 made a holding plate out of the drop that was all that was left out of a 6 ft. stick of 1 1/4 x 3/16' cold roll flat bar after sawing up some parts today.
