    You might check your torque calculation. Using the numbers you are using, the equation should be (torque will be in ft-Lbf): [tex]P = \frac{T \omega}{5252}[/tex]

    I would do a quick and dirty compare using a rule of thumb based on distortion energy

    [tex]T = \frac{\pi d^3}{16}(.58 S_y)[/tex]

    I think you've got the right idea though.
