I couldn't find this info on Google. What is the proper material to use to
replace the pin on a Bridgeport drawbar? I tried a roll pin which was way

In eighteen years of teaching high school freshmen and sophomores I
have never had a student break a BP drawbar in that fashion. Perhaps
you are putting WAY too much oomph into your spindle tightening.
