[TowerTalk] pushing a mast up at the top of the tower

[Stan Stockton]

There could be a better way, but I have always used a come-a-long  
attached to the top rung of the tower and a muffler clamp around the  
mast, wrapping the cable with the hook around the mast below the  
clamp,  Loosen the bearings so it will slide through and have a short  
2x 8 board handy to rest the mast on to reposition the clamp to go  
higher.

  I suppose a gin pole, fully extended, with a clamp on the mast  
already through the top of the tower would also work and could be done  
with everyone on the ground until after it is extended to where you  
want it.
