 Posted: Tue Jun 14, 2011 7:03 pm Post 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!

Where did you get the laser and what model did you purchase? I can see where this could really help out with several areas of alignment!

Nice pics Bill S - that should help many.
Regarding the laser - am I correct in thinking that you only used one
axis of the laser for the wheel alignment?
I chose to get a cheap, 1 axis, non-leveling laser (Sears) because I
just couldn't understand what to do with all the functions. Turned out
I did the hoist off the floor routine with the 1 axis and never wanted
more for that job.
However, I really like the laser now and will definitely be getting a
self leveling 2 axis laser sometime after flying this thing. Wish I had
it for my deck project. So I'm suggesting you can do the wheel
alignment thing, hoisted or not hoisted, with the cheapest unit you can
find. And using it will be a lot better than not having it. But a
nicer unit has a lot of other uses on the plane and elsewhere if you are
into it. Do you agree Bill S?
Anyway, I really struggled with how to hoist the wing-less fuse and
thought long and hard about how to avoid hoisting it. In the end,
someone on the list described using pieces of lumber, vertically, under
the spar stubs. With 1 small hydraulic jack, and some 1.5 x 1.5 oak
sticks, along with a HF engine hoist, I got the whole thing up
single-handed with surprising ease. So, another data point.

Hoist, use a lot of little people or rent some Egyptians the kind that built the pyramids.

Yup, only used the vertical on the wheel pants but found lots of uses for
the horizontal as well. While it is obviously a RV builder required tool I
am told you can do stuff like hang pictures, build decks, storage buildings,
etc.... Go figure  It is a

Just Google self leveling laser and you will get a lot of hits. Probably a
lot better for a lot cheaper today!
