[TowerTalk] Removing a Rotator

[N3XX - Tim Heger]

To hold the mast in place while replacing the rotator, I use three flat 
steel bars about 1 foot long.  I drilled holes for U-bolts on each end of 
each bar, spaced so that one U-bolt clamps to the mast, and the other clamps 
to the tower leg.  All three bars are clamped to the mast just above the 
rotator.  The other ends of the bars go to the three tower legs, and are 
clamped there.  This has always worked well here, no sideways movement of 
the mast, and the thrust bearing holds the vertical pressure.

GL & 73,
Tim - N3XX
