Sorry for the split post. I forgot to mention that Wright County (I think
that's where you are) is an 80 MPH windspeed zone. In that case for your
setup, you'll have a bending moment of 30,785 in.lbs. You'll need a mast with
58K PSI yield strength and 0.250" wall. 80 MPH has approximately 25 PSF wind
pressure. So you're even worse off.
