Hans,
Nothing structural is attached to my house. There's
approximately 1/2" clearance between the TRX80HD
Raising Fixture and my gutter.
The first few photos are of the orginal owner's (John WO6R)
installation. He installed it too close to his house and the
fascia board needed to be trimmed for clearance.

Bryan,
The only thing I don't like with your pictures is how you attached the lifting
block to your house. I get nervous each time I see something attached to a
house with no apparent enforcements.
How did you determined that plank to have enough strength to lift your tower?

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.
