cuts when pushed axially; the cutting edge is oriented vertically). Set the
compound to the angle of the taper. Mount the cutter on the toolpost. Lock
the spindle firmly in place (you'll have to cobble something together to do
this). Lock the saddle in place. Use the compound screw to make the cut,
and use the crossfeed to set the depth of cut. Its tedious, but can be
done. Basically, you're using the lathe as a manually operated shaper.
