Hi Dave,

I would like to hear you tell us that you install the steel pipes WITHOUT
climbing the tower, and then tell how you do it.  Tall bucket trucks are
expensive to rent and I suspect hardly anybody bothers with them to install
crankup stops.  They either leave the stops out or climb the tower to
install them . . . two really BAD ideas . . .
