Ron, the clamping ring for N connectors is nickel plated. You will turn the 
 coax to charcoal before successfully soldering the shield to it.
One of the major failure modes with N connectors is having the shield work  
loose due to pulling and twisting the cable. A short piece of heat shrink 
tubing  over the clamping end of the connector and a couple inches of the 
coax will  provide excellent reinforcement and improved reliability.
The recommended connector installation procedure has worked very well for a 
 lot of years.

Just  getting ready to install some a new beam and  coax plus N style 
male  connectors on a new tower.  It's been awhile since I last used one 
(N  style) and have reviewed via the WEB and the ARRL handbook 
recommended  installation methods and find two different methods with 
respect to the  barrel and shield connection.

The barrel I am referring to is the small  piece were the shield is 
folded back over and then compressed and held in  place by a O-ring, 
washer and screw in clamp.

The ARRL handbook  does not call for any solder of the shield to the 
barrel peace but on one  ham web sites recommends that the shield be 
soldered to the barrel insert  piece and then assembled the same way as 
the non soldered.  If I  remember and it has been some time since I used 
N type but I believe I did  not solder the shield but relied on the 
compression and clamp fittings to  make good contact from the shield to 
the N fitting.

Would  appreciate your opinion, to SOLDER or NOT to SOLDER.
