Hi Larry,
If I'm not mistaken Bernard referenced 1650 as a cruise RPM in the F&G. My
home-made prop is a 76/46. Seems to work fine.

Subject: Pietenpol-List: Elite Pietenpol purists only!
What do you other model "A" guys use for a cruise RPM? I could have sworn t
hat Mr. Pietenpol used 1850 but I can't remember where I got that number. (
Not that I'm getting forgetful but in my line of work some things get a lit
tle fuzzy if I don't use them often.)
Also, I'm polling the faithful for prop sizes. I'm running a 74x48 but agai
n, I seem to remember that Mr. Pietenpol had a range that he recommended th
at had a lot less pitch.....I think, maybe, possibly.....or maybe not.
Chet Peek's book has some references but I can't find my copy right now and
I'm not too sure where he got his info. I believe it differed from what I
had heard.
Thanks for your help!
Larry

Hey Larry,
Though sadly, not an official member anymore of the EPPG (Elite Purist
Pietenpol Group) I can say that my years of research and the18" thick stack
of back issues shows The predominant Ford props seem to be 76X42 and 76X44.

Per the Bible...:
"The airplanes that we build for the Ford engine (i.e. Air Camper/Sky Scout)
weigh approximately 620 pounds empty. They carry two 170 pound people with
the engine throttle less than half open. We recommend the engine to turn
over at 1750 RPM on the ground and cruise at 1650 RPM in the air, although
they will turn up to 1900 RPM in the air at full throttle. However, cruising
at 1650 RPM reduces the amount of maintenance that is required for the
engine."
On props; he talks about the important factors for a prop, and how they
tried many different ones before arriving at one that provided the best
results, then this:
First of all, the propeller must be of good design, good materials and
efficient. The diameter should range from 6' 2" to 6' 6" and have a pitch of
4' 0" to 4' 3". The propeller should turn from 1650 RPM on the ground to
1750 RPM with the 4' 0" pitch."
Chet's book echoes these comments. He does also include an anecdotal
paragraph about a drawing Orrin Hoopman made of a recommended prop in 1933.
It was referencing a "stock" prop made for Bernard by Ole Fahlin. The
drawings indicated a 44'" pitch, but later measurements showed it was not
constant. He concluded that the effective pitch was "too much Bite for the
Model A"....
If any of you do not own Chet's book yet, you are wrong. Buy a copy!

<http://www.threepeakspub.com/>If you don't have the F&G Manuals yet I would
recommend just getting the "Builder's Manual" from the family. Support them,
it contains the text and pics concerning the Pietenpols from the F&G
Manuals, and it also has notes, tips and tricks, etc that you won't find
anywhere else: http://www.pressenter.com/~apietenp/

Oh, absolutely, Don! That's one of the big reasons I even considered buying the
Hatz - their annual reunion is at the same time at Brodhead.
However, I have been informed that I'll have to park it away from the Piets. Talk
about separation of the classes, eh??
;-)
Another reason is that my dad knew Johnny Hatz and I've visited his farm way back
when I was a kid. I just stood in awe of one the biplanes he was restoring,
an OX-5 powered Waco 10 or Bird if I recall correctly. I've been smitten by
the biplane bug ever since.

Shouldn't it be against the rules or something to post pictures like this?
Actually I appreciate you posting them - but it does hurt.
Best of luck and God's speed.
