[Public-List] Wires through the mast

[Jay Davenport]

Mike,
 
Gord's wire tie solution to cable noise in the mast is a good one. I use it also.
 
When I rewired my mast, I wanted to avoid having the weight of the coax hanging on the grommet through the side of the mast. Using a large bolt that already ran through the mast from one side to the other (perhaps to secure vangs for the upper shrouds), I simply brought the coax up the mast to the bolt, and then circled around it, before exiting through the grommet. This way the bolt carries the coax weight, not the grommet. I believe that I also secured the coax in place around the bolt with a heavy wire tie.
 
Jay

Hello friends - 

SURPRISE had a similar issue up at the masthead... I found that in addition
to the chafing problem, the sheath of the masthead light wires had suffered
badly from UV deterioration.   I have wrapped the new wires with tape for
protection from the sun.

Another problem SURPRISE had was the sound of wires slapping inside the mast
as she rolled at anchor.  I solved that one by attaching plastic zip style
tie wraps on the new wire as it was fed into the mast.  I chose a size of
zip that had a long enough tail that it pressed against the inside of the
mast and kept the wire pressed against the opposite side.  The mast has been
silent since.  Was I proud of myself for being so clever?
