: Mark?
: That is a 100 HP motor with a 9-1 gear ratio?

: Be sure to supply ample dia. shafts.!!
: I'd go with either the 15-5SS or 4140HT if it were me.
: ... geeeze ... be careful, a slight % error is
: going to result in a large difference in forces.

: Note: 15-5ss has a wonderful ability to take flex
: and twist and hang in there, grain is important to
: consider, but in a round bar the grain will be
: linier as you want it to be. .... geeeze ...

: I've never designed a torque shaft so big and
: with such forces, I hope someone else has and will
: support or correct my suggestion. Please do not
: design these shafts on my suggestion alone for
: this reason. ...
