[TowerTalk] swaging tool

[David Gilbert]

I fully agree.  I don't understand the point of swaging when an inside 
coupler is an extremely nice fit, leaves a uniform outside diameter, and 
for the same amount of strength has no additional weight.  In fact, a 
swaged joint is going to be weaker because of the deformation and stress 
on the swaged portion.

Not to mention how far simpler it is to do the inner coupler.  I just 
use a nail punch and a hammer to make a few dimples that lock in the 
coupling just fine.
