[TowerTalk] Crank up tower standoffs

[Grant Saviers]

You really don't need a thrust bearing with a tower that has a sleeve.  
The sleeve takes the side loads and the rotator the weight.

The mast will rotate freely if straight and if the rotator is aligned 
with the sleeve.

I can drill the holes myself but was wondering  if I should place the standoffs so that they extend from the tower as much as possible, of the other way around. Obviously I'll be using the longest standoff at the top and working my way down to the smaller ones. Of should I just center the standoff arm in the tower channel of each section and let the various lengths determine the distance from the tower?
