Lowell,
You never cease to amaze me, they look great. Now if I am reading this
correctly, are you saying the entire fairing is made of aluminum and the "V"
end is from a fiberglass mold?

I have been watching this. On my first Model IV, I did as suggested,
sanding off the extrusion lines prepping with micro and painting. I used
fabric at the V end as that what was the manual's way. This time, I had the
PVC, but weighed them and this time my goal is to be as light as possible so
went the aluminum way. They came out pretty good, though it was a ton of
work - mostly in figuring out how to do it. Finished they added 3.5 lbs to
the weight of the bare powder coated strut. To cover the V, I used two bid
fiberglass moldings and micro. We may be able to eventually offer these as
a kit.

I have been working on the new header tank, among other things, and I have a couple
more questions about it.
First it seems that all components used for my fuel system is 1/4" so I am going
to replace the two in barbs with 1/4". Is there something wrong with this?
Hope not.
I am also looking at the blue elbow which leads to the engine from the header.
I am familiar with compression fittings but I can not figure this one out. What
size tubing goes into this nipple? None of the tubing I have seems to fit
and it is 1/4" aluminum. Also, I can not for the life of me find the 'nut' needed
to complete the compression fitting. I have searched on Aircraft Spruce
for over an hour and gone through the builders manual and can not find the name
of this part.
Someone please help.

Lloyd,
Not exactly as you describe. The fairings are aluminum - .014" thickness.
They are trimmed to come together in the V. Then a fiberglass shape about
2" wide and appropriately contoured (from a mold) is glued into the V with
Hysol and then faired in with micro. For those wondering about the very
thin aluminum, I poured two part Urethane foam into the structure for
rigidity and to hold the skins in position. I thought of putting the "No
Push" stickers on them, but after finishing, I don't think they are that
fragile. As I mentioned, I wanted the speed from the fairings, but didn't
want to add more weight than I had to. Incidentally, I planned on using the
two part Urethane under two BID fiberglass on my first project. I had
everything made up and was ready for the install when a neighbor at the
airport told me of some serious corrosion from the urethane foam on
something he had done. I definitely didn't want corrosion on the lift
struts so trashed everything and went with the PVC. I did a mock-up
though, using a piece of 4130 steel tubing. I masked it lengthwise and left
one third clean but bare. The other two thirds I sand blasted. Half of
that was painted with the epoxy chromate primer available then and the other
half remained sandblasted but unprotected. Then the whole thing was
assembled as planned using a section of fiberglass with the foam. I had
three stripes, natural metal, sandblasted metal and sandblasted and anti
corrosion primed. I cut of sections of the foam and fiberglass periodically
over two or three years and found no corrosion what-so-ever on any of the
surfaces, so this time, I believe it is a non issue. Maybe he used the foam
from a spray can - I don't know.
Another note. My equipment won't handle full length material so each length
of tube is covered by four aluminum sections. The sections are formed so
they pretty much snap together. Aluminum bands are positioned and Hysolled
over the joints as seen on the lift strut brackets - second picture.

I hope someone else can figure out what you're asking, because without
pictures I can't. If nobody else replies shoot some pictures or
reference some manual pages / pictures and I'll try to help.

James,
If you are looking at the typical factory fitting, it is for 5/16 tubing and
the parts you are looking for are as follows:
AN818-5D "Nut"
An819-5D "Sleeve
You will need one of each for each connection. don't forget that you will
need them at the fuel valve as well as the termination of the aluminum line
at the firewall. My system includes the compression fitting at the header
tank, two at the fuel pump, two at the fuel valve and one that runs to a
hose barb just forward of the firewall. I just finished my new project
system and am well aware of the frustration finding parts - lots of bushings
to change pipe thread diameters etc. Also keep in mind that aircraft
compression fittings use a different angle of the flair than the typical
hardware type - as I understand it, the typical AN fitting we use has a 45
flair and the hardware store fitting flair is 37.
If your fitting happens to be for 1/4" tubing, then the suffix would be 4D
on both. On the Model IVs the wing tank to header tank tubing was typically
5/16", however I know of guys that have changed to 1/4" throughout the
system and have flown hard with no fuel flow issues. If you are running the
582, you might think about 5/16 as the fuel consumption is a bit higher than
the 912.
Lowell
