[TowerTalk] How To Avoid Telescoping Mast Colapse

[EZ Rhino]

I built a 50' mast of this very stuff...chain link fence top rail, starting with about 2 1/2" or so at the bottom and tapering to 1" at the top.  A falling derrick method is the best way to get it up, but I actually built a truss to keep the majority of the length of it "straight", and just picked it off the ground at the halfway point and walked it up, while a friend pulled one of the guy ropes to help out when it got over 45 degrees.    I use a four guy system at two levels, 25' and 40' (I think).  When you start pricing the pipe required for this you will find it is cheaper to buy a ready make mast like the Tessco.  However if you have the stuff lying around, it works great.

If the goal is just to get something up to 44-50 ft... rather than a 
push up mast (which has the advantage of small storage size and being 
able to be pushed up within a small area), why not something like a 
couple lengths of galvanized fence top rail with a coupler, or two 
different sizes with a reducer.  Lift it up (falling derrick works 
well), and guy it off..
