I second what Joe proffers, I lost [dropped] my mast last year about 10-12
feet weighing near 350-400 pounds with all included, and geez oh Pete, a
small bottle jack was all i could get to fit in the circumstances, and to get

the jack per effort then reset the clamps and start the whole sequence all over
till it was finally raised back up and in place... watching paint dry would
have been more fun.. mac/mc w5mc
