Sorry Chris, but this is one idea I can't agree with. A 30' drill bit is  
not controllable. I still like the foam pipe insulation the best. I also 
don't  like drilling holes into a very expensive piece of extruded aluminum.

Ah  Rummy,
That was a concern (right after doing the job). For  $7.50 on sale at
Harbor freight tools, I got a 3/16 fiberglass wire running  kit.  Attached a
1/4 inch drill bit and tested the concept on the  tomato can lump of foam.
Just manually, it was an easy "drill", probably  fix it to work on the
cordless drill too..  Phew! panic solved or at  least delayed. 
The pieces make a rod 30 feet long, so long enough to do  the job.

Chris,
So what will you do when  you need to replace or add any wires?

Hey  Mike,
The cable slap was  driving me nuts last year.  My  solution was to
measure the  diameter of the nipple on a can of instafoam  drill one size
larger  hole into the bottom of an empty tomato can and  "test" how much  
came
out in a second or two when I pressed the nipple into  the hole.  Once I
established the volume released for the time With the mast   laid down I
drilled a series of holes on the front of the mast about  4-5  feet apart.
Stuck the foam can into the holes for the right  amount of time  (about 1.5
seconds) and easily and quickly solved the  problem.  The  advantage of this
method is that I also  compartmentalized the mast so  should I ever take a
really bad  knockdown and put the mast under the water  (only happened once 
 
so
far to me) I won't have the void where the wires are  take up  the extra
weight in water.  This last trip no wire slap.    (did have a little IMF 
tube
rattle, but haven't figured out how to  fix  that).  Hopes this helps.

Subject: [Rhodes22-list] silencing internal  mast  cable slap


I read here that folks have used pipe  insulation to  silence the "cable 
slap"
from the cables running  inside the mast.  I  just put two 6' sections of
insulation onto  the radio and masthead light  cables, but that's all I was
able to  push on.  I think that the  insulation is hanging up on the bolt  
for
the spreaders.  I imagine  that if I pull that bolt I'll be  able to push 
more
insulation up the  mast.  

My  question is: Is it worth it to pull the spreader bolt  or is what I've  
got
in there so far (about 12' of insulation) enough to end  the  cable slap?  

As you can tell, I'd prefer to not pull the   spreader bolt if I don't  need
to.

Thanks!
