Christopher.
I too have been using this method for years, and posted it
to the list some years ago.
Again, I was taught this by Bill, N4AR, whose station in
Lexington was apparently amazing - 4 200 foot towers with a
box 4 of 6 elements on 20M pointing toward Europe.
I am sure that he wouldn't have wanted the outer to come
away in those circumstances in a flash frost in Kentucky!!!

Subject: Re: Another method of soldering PL-259's
Does fully assembled mean that you don't unscrew the outer
piece and slide it back on the coax as you normally would?
Also, it would take a lot of solder to go all the way around
the connector. Not sure how the braid would be held in
place while you solder.
Finally, this method may be designed for large diameter
coax.
Anyway, it's certainly worth a try. The connectors you buy
these days are all coming through crimped.
