| Subject: | Wheel Fairing/ Plane Leveling with Laser |
Ok, I also did the unthinkable easy thing and it was on an RV7a. I did NOT
hoist the airplane up to put the wheel fairings on. I used a laser that
gives both vertical and horizontal planes to align the wheel centerlines up
with the fairing and then with a line offset from the centerline of the fuse
at front and back. I think these pictures will tell the story.
Did both in an afternoon along with the leg fairings. It was possible to
get them absolutely parallel with the fuse centerline. Granted in flight
they hang at a slightly different angle but the important thing is that they
be parallel with the centerline airflow. I have zero rudder trim in cruise
and the ball is centered.
That is a Stanley Vert/Hor Laser and is self leveling. Lots of uses in
setting the emp because it allows you to square two surfaces like the vert
stab and the Hor stab as well as checking for level in Hor mode.
This what I did:
Dropped a plumb line at the rear tie down and made a mark on the floor.
Then aligned the laser with the mark and the center of the front gear leg.
(yeah you could pull a plumb line but the laser is easy). Mark the floor
for the fuse centerline.
Then measure carefully from the fuse centerline to the tire centerline on
each side. Note the tire is tilted. Then shoot a line across the bare tire
with the top center tread, be sure to align a mark about two foot in front
of the tire the same distance out from the fuse centerline and align with a
equal distance mark at the rear tie down. Now you know the exact parallel
line that the fairing should match when installed on the tire.
Once you have that line, keep the laser in place and mount the wheel
fairing. Then simply align the fairing parallel with the laser line and you
automatically match the fuse centerline. Adjust the fairing for parallel to
the ground front and back using the plan measurements. Carefully drill to
brackets and you are done.
Set the plane up again the same way with appropriate distance and reset
lines for the leg fairings. Used a line and slip ring to verify the leg
fairings were aligned with the fuse and set them. After that, I matched the
intersection fairings to the leg and wheel fairings.
Hope this helps! If you want to hoist then hoist, this is just another way!

Sounds right.
Since you are assembled and flying, this may not be feasible.

With nosewheel removed, there's only the need to jack the main gear off a
minimal distance.
BTW, I found a simple laser line shot from tail forward provides a great
centerline. You can actually split the rivets on the fuse and split the
nose gear. Then used a piece of angle iron on the floor. The angle iron
was heavy enough not to move while hitting it repeatedly with the measuring
tape.
Knee pads will be good too.

and laterally. To get it level longitudinally, the nose wheel is 1/16", but
the mains are about 2" off the ground. I am leveling to the F-1015C mid
cabin deck.
