Re: Tapered Pins

.. of course I can make my own but for a one off project, but for a
repeat stock job I would like to buy them premade.
I'm cutting a mold for somebody that casts a body with a through hole.
There are nominal dimensions, but a tapered pin that knocks out easily
would be acceptable.  I can buy "standard" tapered pins and "standard"
tapered reamers, but when I was trying to spec it out it seems the pins
are available in sizes ranging down much smaller than the small end of
the reamer.  Or in other words, "WHAT?!?"
I went ahead and bought a couple sizes of pins that would be suitable
for the casting, and a 0-10 set of tapered reamers.  I don't know how
its going to work out, but I figure if worse comes to worse maybe I can
make a tapered D-Bit reamer that actually matches the pins.

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.
