Ham 2 gets my vote.
I used a similar method, only I used three 2 x 4s approximately 24" long
nailed together to form a U shape, with the inside distance of between the
legs of the U the same as the outside distance of two tower legs, Rohn 45G
in this case. I fastened three lengths of string to the U frame; one on the
inside of each leg of the U, & one to the center of the U. The lengths of
the strings were appropriate for the distance from the tower base to the
guy anchor posts. The two outside strings fastened to the outside tower
legs, while the center string went to the center leg. By carefully pulling
the strings taught against the first section of tower (already in place)
with the 2 x 4 U frame & keeping the outside strings against the inside of
the U frame legs, I could find the necessary center of the anchor post
hole. I used a heavy weight to hold the U frame/string apparatus in place
on the ground while I marked "the spot" with a stake. A tape measure was
also used to match the distance between strings to ensure the proper centering.
I found digging the hole with similar accuracy much more difficult than
locating "the spot", even with a small tractor & post hole auger.
