[TowerTalk] 40-2CD Mods/Coil covers

[W4nf@aol.com]

Hello all,

I'm down to the last part of the W6QHS (? call) mods for the beam.  I 
modified the coils by removing the sheet metal screws that terminate the coil 
on to the element and drilled completely thru and inserted a SS screw and 
nylon insert nut in its place.  In doing so I had to cut a portion of the 
shrink tubing that covers the coil.  I tried to slip 1" heat shrink tubing 
over the whole assembly but the new screw and nylon insert nut stick out to 
far for it to go over.  So I ordered the next size McMaster and Carr had 
which was 1 1/2" dia shrink tubing.  This fit over OK (in fact real loose) 
but did not shrink down small enough to provide a good seal.  So, today I 
reordered some 1 1/2" shrink tubing that is suppose to shrink down more (3:1 
shrink ratio).  I hope this works.  Anyone have any other approaches or 
sources for say 1 1/4" shrink tubing.  Thanks and 73, Jack W4NF
