Hey TT-ers;
Just thot I'd share a bit of info w/y'all.
1) a good place to get 2 x .250 6061T6 extruded Al tube is Dillsburg 
Aeroplane Works.  Mr. Charles T. Vogelsong, (Ph. 717-432-4589) owner, 
charges $5.84 a foot for that plus S/H.  UPS will take 8 foot pcs (not 6 
foot as I was told).  That is what I wanted.  He even cut a pc. of 12' to 8' 
and 4' at no extra charge.

2)  The top sect of my new tower is a 25AG2 (pointy top to some).  I have an 
almost new one to put up.  It has, as u know, a pc of TS 2'9"  2 1/4 OD 14 
Ga. wall at the top which I will use as a brng (sort of) for the 8' pc of 
Al.  When I tried the 2" pc of Al it wud not fit...*&%^$#!!!  Upon exam I 
noticed that the TS where welded to the legs (taper portion) had weld 
intrusion inside the tube (watch for this).  This was 1' 6" down in the tube 
from the top and was pretty hard to get rid of.  I brazed a bastard file 
round side out to the end of a pc of 1 1/4 inch 2 foot long water pipe and 
worried away at the welds for a cuppla hrs until the Al cleared just fine.

Now...since I've shared these two good bits of info w/u 'bout a 
question?  I plan on only 2 small antennas up on this tower...5el(18' boom) 
or 7el(30' boom) 6m at the top and A3WS just above the top of the tower.  I 
know some of y'all have done this b4 so tell me how it works to put the Al 
inside the TS top...corrosion prevention etc.  I thought abt gluing some 
real thin Teflon or a cuppla kids place mats (very robust mtl) to the Al and 
see how that fits...questions...comments?  (be nice pse) 73/dx
