Fellows: PLEASE!!! PLEASE!!! PLEASE!!! DO NOT USE EMT FOR TOWER
I spent many years in the electrical supply business, and EMT Electrical
Metalic Tubing is just that, TUBING. It is cold rolled steel and then
"lightly" galvinized! EMT is made to be bent, EMT is made to be used
inside only!! Ask any electrician and he will tell you that EMT is
"Cheap" stuff and should not be used for any load handling duty. I
wouldn't use EMT for anything heaver than a pipe to hold my tower rope!!
If you must be "Cheap" with your mast material please use at least the
Chain link fencing posts or top rails, at least this stuff is "Designed"
to be used outdoors. A trip up the tower to remove even a vertical that
is attached to a bent piece of mast material is no fun!!
