Anybody could tell me how much ground clearance is
ideal for the propeller... I feel that 9" would be
good, but I don't know what is the "best practice".

--> Zenith-List message posted by: "Scott Laughlin" <cookwithgas@hotmail.com>
I need some "keep it simple Fred" advice here. I purchased a small bending
brake from Grizzly.com to make small bends (24" and less) and it has a sharp
edge for steel. I was wondering if I could just go at it with a file and
end up with an edge pretty close to 1/8" radius.
The advertisement claims: "Bending is quick and easy with this little
brute! A favorite with our home built aircraft customers."
Any thoughts on whether using a file is a good idea or not? The brake can
be seen at:

I just finished doing the bellcrank pivot, which comes with a 1/4" hole, but
AN3 bolt to go through the bellcrank and supports. --- I bought a foot of
3/16 ID, 5/16 OD tube from Airparts, then drilled (using a drillpress for
accuracy) a 5/16 hole in the bellcrank. I then cut about 2" of tube, put it
in the drillpress, and turned it against a file until I had a snug (not
sloppy) fit. Cut to the proper length with a hacksaw while turning in the
drillpress (poor man's lathe) it rests inside nicely. The AN3 bolt slides
in perfectly, already fitting the bellcrank support holes. A little lube
before assembly, and it should last a long time.

Some where in the FAR's, says you must have at least 7 inches of clearance.
This must be in a ground level attitude.

I used 9 inches, read it somewhere and also went around measuring light
planes at the airport. Had the standard wooden prop (68" dia) reduced to 66"
for my installation. Works fine.

How trailerable is the HD and what mods would assist?
My aircraft is built and I have no idea how easy it is
to rig and derig it but I have seen references on the
net to trailers.
