| Subject: | Re: Tail attachment |
Hi Santiago...There are probably several ways to do the tailpost
fittings but I just made a couple of small 1/8" plywood wedges and glued
them to the tailpost so that the fittings would sit square to the
centerline of the fuselage. It worked out fine. For the front of the
stabilizer most builders are replaceing the #7 wood screws with 8-32 an
bolts through the main beam. I put self locking nut plates on the bottom
of the longeron but again, there are different ways to do that too. I
haven't decided how I will fasten down the leading edge yet. Ed G.

Subject: Pietenpol-List: Tail attachment
I have seen in the archives a question about the attachment of the
horizontal stab to the fuselage (from Rick Holland) that intererst me,
and since it doesn't have an answer I will post it again.
The two bottom fittings are attached to each other with two
horizontal bolts through the fuselage tailpost, however the fuselage
sides are angled. Did you guys makes 4 wedged shaped washers out of
something so the bolt head and nut seat flat or add 2 wood wedges for
the fittings to sit on?
I will use bolts, no rivets.
Another question, I have seen Piets with the horizontal stab bolted at
the leading edge, main spar or both. I plan to bolt it trough the main
beam. What would be recommendable? Thanks
Saludos
Santiago

I am just wondering how may Grega fliers are on the list. What stage is your project
in? What fuselage? What engine? Any other mods?
Myself, I have ordered "Complete" plans from a "guy" in Oregon. We will see what
arrives at my door if anything. I have been practicing my welds, I was getting
a little worried, but I am feeling better about them. I have a Corvair core,
ready for tear down.
Thanks all,
-Ryan

| Subject: | Re: lowell frank's stats-- Roman's Drawings |
BTW, Roman's Riblett airfoil drawings are rib plots, which really help. I believe
that I recall that Roman took pains to make sure that his drawing dimensions
are true to the numerical plots. In other words, his drawings are not just
a cheap copy job, but a blueprint quality copy. I have only seen the 613.5 drawing
myself, but was glad to get it.
This is an unpaid testimonial.
FYI, I believe the full names of the two Riblett airfoils are the Riblett GA30A612
and the Riblett GA30u613.5, but I have been told that Riblett may have dropped
the letters in the middle of his former nomenclature. A likely "almost right"
explanation follows:
-- The "GA" stands for "general aviation,"
-- the "30" stands for how far back on the chord (as a percent of the chord, from
the LE) the thickest part of the camber fits, and
--the "12" or "13.5" is the maximum thickness of the camber, expressed as a percent
thickness of the chord.
Laid against a Piet rib, the Riblett 13.5 is about an inch taller in the upper
surface and an inch lower in the lower surface. The Riblett nose is much more
rounded until after the first 30 percent of the chord. There is a VERY slight
undercamber on the lower airfoil surface, like the Piet, but only toward the
tail of the airfoil.
Overall, the airfoil looks quite a bit like a Clark Y that is taller (thicker).
However, the Riblett's lower surface drops lower below the chordline than the
Clark Y in the first third of the chord, and thus looks more like a NACA 2412
or 4412 below. It's more laminar below than a Piet or Clark Y.
The spars can be at least two inches taller than the Piet's, and thus both heavier
and stronger. This might be a good application for a built-up spar, like
"Peter's Piet" Down Under.
These numbers and comparisons are all somewhat inexact, but good overall impressions.
