[TowerTalk] Fwd: Boom-to-Mast Tilt fixture

[Hans Hammarquist]

Bryan,


Theonly thing I don't like with your pictures is how you attached thelifting block to your house. I get nervous each time I see somethingattached to a house with no apparent enforcements.


Howdid you determined that plankk to have enough strength to lift yourtower?

Alan,
 
I'm able to tilt my US Tower TX-472 tower over with my Force12 C-4XL on it, in 
one of two ways
w/o a tilt fixture...
 
The yagi boom is 30' long.  With the use of a 12' step ladder, I'm /just/ able 
to reach the u-bolts
on the boom-mast clamp, loosen them, and turn & tilt the yagi as needed. See 
photos at
http://www.tinyurl.com/wa7prc-tower.
 
The yagi boom is in five equal-length sections.  With the tower tilted over, I'm 
able to access
the hardware to remove/install sections of boom + element(s) as needed and 
continue to
lower the tower using this method, I highly recommend finding some way of 
preventing the
mast from rotating. My rotator has a brake, or I can use a section of angle 
stock drilled
to accept u-bolts that temporarily connect the mast to one rail of the tower. I 
used the
latter when I needed to work on the HDR300 rotator w/ my feet on the ground.
 
The above is what you do when you don't have a tilt-plate. Maybe it's not so 
purty but,
they work for me.

Bryan WA7PRC
