I have built 25G up to 150 feet in 30 foot increments between the permanent
guys. I always rope guy near the top of the section I am standing on while I
am setting the next section. Then every 30 feet I install the permanent guys
with enough tension to make the tower stable (and straight by eye). Final
leveling is done with a surveyors instrument.
So the drill is, set a section and bolt it, stand one rung (or two) up on the
free standing section and move the rope guys to the second rung below the top
by reaching up, move the gin pole and pull the next section. I use J hooks on
the rope guys so it is a one second stretch-up to move each rope and the
ground crew then gently tightens the ropes and ties them off. . No need to be
bolting, clamps, or such stuff for the ropes.I am careful not to swing my
weight around while I am standing just above the free standing two sections and
moving the ropes up on the third. By being methodical I have never had a scary
moment.
