[C320-list] Cabling repair without Mast Removal

[Allan Field]

I am not too sure I understand your problem but let me take a stab.  It
seems that you want to enlarge the hole on the deck between the bottom of
the mast and the top of the compression post.  Since the cables pass through
the compression post, I don't know how you would do this without removing
the mast.

That said, there may be another solution if what you are trying to
accomplish is to get to the fittings at the base of the mast before the
cables pass through the deck.  That possible solution is to cut a "window"
into the bottom of the mast large enough to get your hand into to do your
work.  Then have a piece of mast material a bit larger than the hole to
place over the hole and screw into place.  I have actually seen this done
before on my old boat.

Hope this helps?

Subject: [C320-list] Cabling repair without Mast Removal

On my, new to me, 1995 - # 205,  The mast was removed and the interior mast
cables disconnected last winter for some survey repairs.  This spring the
Radar did not work, but due to scheduling, I had to start the 700 mile
delivery on Memorial day weekend, so could not wait to find a service tech
to determine the problem. I have now confirmed that the problem is the
cabling between the Antenna, and the display. In order to avoid the cost of
removing the mast and totally retuning the rig, I would like to enlarge the
hole at the base of the mast enough to allow the internal connector to pass
into the bilge area.  Then replace the cable section to the antenna, and
re-terminate the cable ends.   Any suggestions as to how to enlarge the hole
without damaging the existing cables? Any suggestions as to hole shape to
maintain structural integrity? I am considering drilling second larger hole
above the existing and then using a dremel tool to finish the penetration
when it gets close, and smoothing the edge burs. 
Thanks,
