[TowerTalk] Mast vs. R45G part deux

[Larry]

When I put up my 45G I had hoped to insert a 20 foot 2 inch 95 lb mast from 
below through the tower sections but I found there was no way to get it in 
without bending the mast (neither useful or likely). I ended up lowering the 
mast into the top with the long (20 foot +/-) gin pole  Fortunately I 
haven't had to take it down yet but I would use the gin pole again and pull 
it out of the top of the tower. I tied the mast above the halfway point so 
that I could somewhat easily pivot it to insert into the top thrust bearing. 
That might not be so easy if the mast was much heavier, say 200 lb. If you 
think of the "pointy" top as a thrust bearing of sorts the same scheme 
should work.

Hi, Steve,

I'm the pres of a club that does several take downs every year for widows
of SK's. Disassembly is evidently the inverse of assembly, but the fellow
who put it together isn't around sometimes to ask.

We ran into this a couple of years back with a 2" x 20' mast on 4 sections
of 45G.  After removing two sections, the mast absolutely would not go
through the face. We ended up using the gine pole pole on the 2nd section
and a rope attached low enough on the mast to extract the mast through the
top. We thought it would go through the face, two, but it will not.  We
demonstrated this on the ground after we took the tower down.

This issue cost us an hour or so of trying to remove the 2nd section over
the top of the mast - nope, sorry, there's only 12' or so of gin-pole, the
mast had to come out first.

73 and I can't believe I can actually help you for once!

Mickey
