Kim What's the model of that SteppIR? It's time to do our own wind loading model, I think. Do we have good info (is Doug answering e-mail?) on the mast and rotor hardware? While I know it's a Grade 8 bolt, I know precious little else about what's up there. gerry On Wed, Nov 30, 2016 at 9:59 AM, Kim Elmore <[log in to unmask]> wrote: > I have a name for someone to work on that mess up there.
