No. A little closer attention to weight and balance, and other rigging
issues should help. It is possible to use the horizontal brace wires to
adjust for nose up/down, too.

John,
I've never seen a spacer like that on a Pietenpol. Have you run an accurate
weight and balance on the airplane? My guess is the plane was quite
tailheavy and they needed more lift out of the tail. If it is that
tailheavy, you should conisder moving the wing aft to get it somewhere close
to the normal CG. Pietenpols tend to be tailheavy, and while the airfoil
can accommodate cg's slightly aft of 33% MAC (20" from leading edge) I
wouldn't push that.

| Subject: | Wing spar dimension question |
Believe me, I searched the archives before asking, but it still isn't entirely
clear for me---
I began cutting 4130 for the metal parts and have moved on to cutting for the cabane
and spar butt joint straps. I had always planned on building the 3-piece
wing but hadn't deliberately studied the plan page until today. I was always
under the assumption from the "Improved Design" that the spar for the forward
wing was 1" wide routed to 1/2" where indicated; the rear spar is a solid 1".
This is how I had planned to do it.
In reviewing the 3-piece center section plans, it says the center section spar
is 3/4" and the wing panel spar is 3/4".
In reviewing the archives, I see people have done it many ways--1" routed wing
spars, 1" non-routed wing spars, 3/4" wing spars.
My question, I suppose, would be this-- I'll plan on using the 1" routed front
wing spars and the 1" solid rear spars as plans indicate, but does this mean per
the 3-piece plans that the center section spar should still be 3/4" (and add
plywood or spruce spacers to match the 1" dimensions of the outer wing spars)
or would I make the center section spars 1" to match the left and right wing
spars exactly? My ribs were built for the 1" spars.
Any thoughts would be appreciated.
Tom

Tom,
Since your ribs are built for 1" spars, I would use 1" spars in the
centersection as well. You'll have to modify the plans slightly to make
this happen. Welcome to the wonderful world of Pietenpols!.
Note that you might want to consider making the centersection spars a
slightly different thickness to take into account the overlap of the strap
fittings that attach the outer wing panels to the centersection. Since
there are strap fittings on the spars and strap fittings on the
centersection, it would be nice if the fittings of one would nest inside the
fittings of the other, but with both spars the same thickness, that doesn't
automatically happen. Since you can choose your spar thickness for the
centersection, you can make that thickness whatever convenient value will
allow the centersection strap fittings to nest inside the wing spar
fittings. Be sure to take into account the thickness of the plywood doublers
when determining what thickness spars to use.

If the shim was added to compensate for a heavy tail.that heavy tailwheel
could be part of the problem. Keep looking, though.

Jack,
Thanks for the input. I suppose, to avoid any additional thinking (or ordering
incorrectly sized spruce), I could just build the original plans wing (as I'd
thought about when I started the project). My reason for choosing the three-piece
wing design is I'd heard the way Pietenpol had originally joined the wing
halves wasn't really regarded as "sound" (even though structurally I've not
heard of a failure from this). Is that true? I suspect others have built the
one piece wing design to plans, but do they join the wing spars as per plans
(angled cuts with vertical bolts), or is there another means (maybe published
or not) by which the spars might be joined in the center that is considered a
bit stouter or more accepted?

In the years since the plans were drawn, the FAA has decided there is a
better way to splice spars. If you don't have a paper copy of the latest
revision of AC 43-13, now's the time to buy it. They specifically reference
splices in Ch 1, starting page 1-15:
