That is how I did it as well..I set up two ladders with a wooden arm clamped 
to each. I hung a plumbob from the end of the arm.....the plumb bob was a 
wrench in a bucket of water to damp out any oscillations. Choose a still 
day. I lay on the ground and  supported my head with my arm. By rolling my 
eyes from the bottom to the top of the tower,  I was able to judge the plumb 
to within half the thickness of the tower vertical members.
