Hi working on new gantry router design and intended to use 3"x3"x10'
1/4" angle iron spanning 8-10ft between support legs and predict a load
of approx 100lbs. I am concerned with deflection or twist. if secured
to supports diff and or where my load rides on the angle iron would change
the amount of deflection. If I uploaded pic properly it might give an idea of
what I am trying to do.
