South Bend used taper pins on my lathe, some of which didn't survive the
students' abuse. I acquired some spare parts which had been drilled
differently for the taper pins.  It seemed to me the idea was to ream by
hand, tap in the pin and then cut off the excess.

the theory

 The thing is there really isn't any point to having stock size taper pins available more than minimally longer than you can ream.  I was excited to see a couple pins available that might fit my application only to find I would have to create my own tool to ream the holes.  I can make my own tools, but it takes a lot of time.
 

I'm an idiot.  Since the taper is the same 1:50 for inch tapers and 1:48 for metric tapers of all "standard" taper pins I can just use an "off" size reamer to finish out the hole.  Doh!
