Re: re: tapers post (for smoke)

Smoke,

Regarding tapers....you mentioned making some tooling for 5C, etc.
In case you're making a spindle to seat a 5C, be aware that on work
holding collets like 5C's the seat and the collet don't have the
exact same taper. I've forgotten all the details, but when we were
regrinding the 5C taper in one of our Hardinge lathes Hardinge techs
told us to have the spindle angle something like about one degree off
from the collet angle.

Not sure if the above is true for a tool holding collet like an R8.
