 Posted: Sat Aug 16, 2008 10:03 pm Post subject: Nose wheel fairing length |
 |
|
Help, please.
Amazingly, I could find nothing on this issue in the archives...
When I slid the rear nose wheel fairing in place and fully forward
against the vertical post, I found that the aft end of the fairing was
_exactly_ one inch behind its proper location according to fig. 3 page
48-17. Now the instructions (same figure) say to "TRIM FLANGE IF/AS
NEEDED". If I did that , I would trim right through the flange and
1/4" into the body of the fairing. The forward fairing half would be
pushed forward a like amount, and the specified cutout(page 48-18 fig.
1) would not even be close. Clearly there is a mismatch between the
instructions and the dimension of the rear fairing that I received.
Either the fairing is too long by an inch, or the 20 5/32" dimension
( fig. 3 page 48-17.) should read 21 5/32". The drawings all show the
fairing essentially flush against the post with little or no cutout.
It may even be remotely possible that I'm missing something here.
Any ideas??

PS This particular aft nosewheel fairing is not as nice as most of the
RV10 glass. Big mismatch of the halves.

I fought with this fairing for a week or two. I attempted to follow the directions and ended up with a cutout that was too deep in the front and rear halves. I ended up reglassing the parts and setting the center of the fairing as pictured in the plans and letting the back end be long. I was careful to keep the center line parallel to the reference plane.
The fairings seem to be of much lower quality than the other plastic parts.

Hey John,
I also remember puzzeling about this. I'm pretty sure I ended up cutting past the flange to make the aft fairing right, then making the nose fit accordingly. It turned out pretty good, I think -- but these pants are really time consuming.
I'll try to remember to take disassembled pictures tomorrow.
Later, - Lew

Hey John,
It took longer than I thought to get back to it but here are the pictures showing the hole cut past the flange in the rear nose fairing. Everything lines up and I don't see why it won't work just fine.
By the way, I ended up reinforcing several times the countersunk holes where the fairing attaches to the gear on all wheels. This still seems like a weak point to me, and we may go with countersunk washers to spread the force ... but then it wouldn't look so slick.

Thanks, Lew. That's a really nice fit, and you don't have to fiddle
with riveting the scrap back!
We wound up just slightly (1/4") fitting the rear nose wheel fairing
to the vertical post, and letting the rear fairing be long.
On the suggestion of an experienced local builder, we put a couple
layers of 9 oz. where the bracket-fairing mounting screws are before
glassing the bracket/fairing mounting pads. Good idea! All seems well.
The forward nose wheel fairing is not thick enough, so there is a flow
"trip" where the intersection is. Doing it over again, I would put a
few layers of glass on the interior of the forward fairing before
fitting and match drilling the two. That would smooth the intersection
and also reinforce the countersunk holes in the forward fairing. Am
contemplating whether or not do to something similar even now,
although keeping the hole locations would be tough. Alternatively, the
area will have to be faired out with micro.
