[SEL] Blackstone keys

[Arnie Fero]

Hi Ron,

Couldn't you measure the geometry of the keyway using an inside caliper
and a scale or an inside micrometer?  When I was cutting keys on a shaper
as an apprentice machinist that was the way that I did a layout of the
needed taper.

See ya,  Arnie

JSI.  Is the taper 1/8" per foot?  Thanks.
