I have 14 10ft lengths of 4 inch square
steel tubing with 1/4 inch thick walls.
Do you think I could use these to build
an 90 foot high guyed tower? My yaw bearing
is a 4" diameter steel pipe that fits over
a 3.5 inch diameter pipe that I would use
for the top 10 feet.
I really don't have any idea how to size
these things. Any help would be greatly
appreciated.
