[TowerTalk] What type of drum?

[Mike Bragassa]

Denny: That has to be a fairly large diameter spool on that drum you are 
using? Not from the subject of room for 600 feet of 1/4 " EHS; but from the 
standpoint of 1/4 "EHS not being so flexible on a small diameter. It is 
always a fight hand-rolling up; say, 150 feet of this cable. Invariably it 
ends up as a 4 foot + diameter 'hoop' of cable; wanting to fight you all the 
way. And, if it gets away from you; "Katy bar the door"! It'll slap you five 
times before you can control it. (maybe I am exaggerating, Hi!)

Let me second Dave's comment... Using rope for a tram line, or small 
diameter cable is asking for a crash... I also use only 1/4" EHS...  Because 
the tram line is pulled into a caternary shape the total forces on it are 
far greater than just the weight of the beam...
The other thing I do is that the tram line is run up to the top of the 
tower, through a pulley, and back down to a ground anchor on the opposite 
side... This way the side thrust is not transferred to the tower... Because 
of having to fly the beam over the woods, etc., my tram line is 600 feet 
overall and is kept on a drum and used only for that purpose.....
