<< The size of the 118,000 psi yield strength chromolly mast I posted is: 2
 inch O.D. x 3/16 inch tk wall.  I use an 18 foot length for my mast.  It
 weighs about 80 - 90 pounds (I don't know exactly, but I was able to
 lift it myself and walk around with it.) >>


2.000 OD, .375 wall 4130CDS (Chrome Moly) weighs 6.508 lbs per foot, mill
finish. Your 18 foot mast should weigh 117 lbs. If it is galvanized, it will
weigh about 123 lbs. If it weighs less than these figures, you may not have
what you think you have.
