   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.
