I don't know if this is the same thing or not. But, I use end mill
holders that have an R-8 taper on the back, and a ground hole in the
front, with a set screw that holds the tool in position. It repeatably
places the tool to better accuracy than I can measure. I made a replica
of an R-8 spindle taper that can be set on a surface plate. Then, I can
read the lengths of the various tools in their holders, and put these
lengths into the tool table. I use a vernier height gauge to make the
measurements. See http://jelinux.pico-systems.com/preset.html
for some text an pictures of the process.
