[Elecraft] Waterproof SO-239 covers

[KENT TRIMBLE]

Mike . . .

I think he might have misspoken when suggesting using pliers to effect 
an extra quarter-turn on a PL-259 after first getting it finger-tight.

The "quarter turn" idea most often refers to the trick of backing-off a 
screw "a quarter turn" and then re-tightening in order to break up 
corrosion.  More than one restorer has brought vintage equipment to life 
by doing nothing more than that.

A second problem with using pliers to scrunch a PL-259 is the risk of 
permanently deforming the barrel making future removal difficult if not 
impossible.

Plier-tightening has its place, but hardly more than the degree or two 
to which you alluded.

Take care of that dandruff!
