That's probably a good design question to ask Vans sometime. The good thing
for me, the way I have my two wings set up in the basement to build, I'm not
sure I could have put the stringer in if it was one piece. I may have had to
relocate my jig. I hadn't thought through the fact they would need to slide
in from the side when I located the jig so the split worked out nice.
There are a lot of interesting "why / how come" questions when building. I
was wondering why the control tubes weren't cut to exact length instead of
coming about a half a foot long. It could be I suppose just to ensure you do
the 51% or there were some standard lengths from the suppliers. I still
can't figure out why I have so much angle left over. I got two pieces about
9' in length with the wing kit and all I had to make was some small pieces
for the flap brackets. I hope I'm not forgetting to install something : ).
These aren't the long ones for the fuselage.

Curt,
Don't worry about it. You will use all of that and more when you get to
the fuselage. Vans ships all the angle for the rest of the plane with the
wing kit since the wing spar box is the only on that is long enough for
the standard lengths. The firewall and front floor stiffeners eat up a lot
of it.

I did ask Van's yesterday. I will post the reply when I get it. Just
thought someone else may have already asked.

Richard,
If I remember correctly, you're supposed to put the outboard J stringer
closest to the top wing skin, then you put the inboard J stringer into place
so it overlaps the outboard J stringer. This fills in the gap that is caused
by the extra thickness of the wing walk doubler.

Hi Dick,
If your talking about the wing, spanwise J-strip stringer, look very
carefully at the plans about how the skins and J-strip overlap. If the
J-strip were one continuous piece, there would be a little space underneath
the skin where it overlaps on one side. By cutting it, it allows you to butt
the top strip up against the edge of bottom skin overlap and the other strip
carries underneath.

Actually it causes a bigger gap between the two stringers than the gap
caused by the wing walk doubler. And it overlaps where the inboard and
outboard skin overlaps - so the gap is somewhat ameliorated by that
step. The wing walk doubler still has its gap.

Hmmmmm . . . Mine fit together really well. I wonder if you cut the J
stringers to the correct length? I seem to remember the overlap of the J
stringers being outboard of the place where the skin overlaps, so it filled
in the gap.

Well, it does fill in the gap (my stringer overlap is where you say it
should be), but the stringers are thicker than the skin so it basically
moves the gap from where the outboard skin is to where the inboard skin is.
I am wondering if I somehow made the stringers out of the wrong raw
materials??? The stringers are significantly thicker than the skin so
where they overlap, it puts a gap between the stringer and the skin. Do
you remember what the dimensions of the stringers were (side #1 length x
side #2 length x thickness)?

Dick,
Looking at your drawing, it appears you made the stringers out of regular
angle instead of J-Stringer material. The J-stringer material looks like
angle that has a curved section added to it. When you look at it from the
end it sort of looks like the curved portion of the letter "J". It is
probably about .020" thick. There is some stuff that looks similar to the J
stringer material in the Wicks catalog. It is called hat section stringer.
You can see it at http://www.wicksaircraft.com/gotopage.php?page=67
Hope this helps,
Mark

I just discovered via Van's that I evidently used the wrong parts for
these stringers... Oh well...

Yes, I made them out of angle :-[ . They fit so well too (except for
the gap!
Back to the old drawing board...

Can anybody help me locate a source for AKZO primer that is cheaper than
Aircraft Spruce, also does this primer provide a moister barrier or does it
need to be top coated.
