Walt,
I would love to know more about what it really is. I had an
opportunity to visit the Canadian Bush Pilots' Museum in Sault St.
Marie, Canada, this summer (two weeks after Brodhead) and they had what
seemed to be an identical engine advertised as a C-2. It must have been
a good enough design for Aeronca to borrow. ;-) Thanks for the info!

John,
Just wanted to give you some input on one of your Brodhead pics. The
one
near the top of an engine on a test stand. You had called it a C2
engine,
but in fact it is some old , French, I think, engine that was like the
type
flown over the english channel for the first time. The original design
had
a "one journal" crankshaft (both pistons move left then both pistons
move
right) This meant that the engine would never run smooth , with two
firings
followed by two exhausts. Kind of how a Harley lopes at idle.
The owner of this engine had my AP mentor , Dick Lawson, who I always
said
could do remarkable things, make a double throw crankshaft. I saw
the
product from beginning to end. Started with a huge block of steel
with
blueing on it with all the scratch marks. Then he cut it out on a band
saw.
Then to the lathe to turn everything but the polished journals, which
was
done by a crank shop. and it was hardened to spec. Those little
breathers
on top were his add on too.
He's now working on a second one for the same fellow.
If you or anyone wants more infro on the engine, I can find out.

The engine in question is a 2 cylinder Lawrence engine going on a
Bleriot
project.

At the risk of preaching to the choir........The most conspicuous external
difference between a Lawrence Twin (used on the Penguin trainer) and the engine
used in the C-2 is that the cylinders in the lawrence engine share a common
centerline. That's why, when one offsets the rods and fabricates a two-journal
crank, it can become a low vibration engine....Carl Vought

Hi all
I've been lurking for quite a while on this list as the Pietenpol is one
of my favorite airplanes. It is the simplicity and back to basics of the
airplane that keeps on drawing me back to it.
I need to make a decision for or against building the Pietenpol.
What I need to know is the useful weight of the aircraft as I've seen
everything from 610 lb empty with 385lb useful (995 lb max) to 535 lb
empty with 715 lb useful (1250 lb max). I weight in at 260lb and my wife
at 120. That does not leave much over for fuel if useful weight is only
385 lb. ;-)
My home airport is at 5330 feet above sea level. If I build the
Pietenpol it will have an O-200 in to compensate for altitude. (Model A
fords are very scarce in South Africa.)
I would appreciate any comments Thanx

The Aeronca E-107-A and E-113A,B&C all had enclosed valve action and the
crankcase faired
into the backside of the prop hub. It is also a fair amount smaller then the
Lawrence engines.
The early engines that were Morehouse and Poole/Galloway engines and looked
a lot like a small
Lawrence engine. I don't think any production Aeronca's flew with these
engines.
The conversion of the Lawrence engine is covered in the Flying and Glider
Manuals. The first one that I
had ever seen was at Brodhead, really neat old engine, puts out quite a bark
too. Didn't know that
they put them on the Penguin's as I've only seen the one in the F & G
Manuals with the single cylinder
engine. Keep thinking about building a Penguin but it would have to be in my
next lifetime as this one is
full up with "want to" projects

Hay gang,I understand that the ailerons on a Piet work
much better if thay are sealed.Can anyone tell me if
the ailerons on a Grega also need to be sealed,or does
the hinging in the center rather than the top allow
them to work better? Thanks,John P.

Is there anywhere where one can buy Sitka spruce locally, around Philadelphia or
Allentown PA? I don't want to pay the shipping that they want to charge at
AS&S. I would consider using Douglas fir but am unsure as to what the requirements
would be to qualify as safe to use in my wings ribs. So if someone has any
pointers on what would make fir good enough to use in aircraft that I would
use that rather than paying shipping.

grega ailerons do require sealing. Most do it by using a strip of fabric.
I'm planning on using a different method. my version can be seen here:
http://www.imagedv.com/aircamper/log/image-pages/03-12-02-aileron.htm
If I were to do it over again I would have rather used pieano hinge like a
Piet. Too late for me now as I have already made all my ribs.

Is any one aware of a PGN, which is a cross between a Piet and a GN-1? They
were designed in Ohio. Thanks\

--> Pietenpol-List message posted by: "ricksilvia" <ricksilvia@lewiston.com>
Hello
I just read the earlier discussion on building a box spar rather than use
the solid spruce spar. Has anyone followed through on this idea?. Has anyone
actually used a box spar in their Piet?
Thanks
