I'm not sure if I am supposed to divulge this, but Gary is still building
ribs because he is secretly planning to turn his Piet into a triplane. He

Welcome "new guy"
My plane started off with a Ford, so I did quite a bit of research, But it's
been a while, so triple ck these numbers. Dan, Larry and some of those
current Ford drivers would be the ones to listen to.
I THINK Larry Williams tried Lion Head, but not dual holes (I THINK) helped
a "tad" if I remember correctly, but didn't turn it into a fire breathing
dragon.
76X42 or 44 seems to be the prop range
I seem to remember that a strong Ford should turn one of those props around
1800 static. If you can get between 2000 and 2100 dynamic, you're doing
well I think. Again, these numbers are old memories now, so anyone else
pipe in. This doesn't count Lowell's Funk/ford which is putting out a whole
lot more hp.
My response to the double mag question is that it is up to you. Some argue
that one mag is a simpler installation with less to go wrong, and done
correctly is fine. Some argue that two mags, though more complex gives the
redundancy. Probably depends on how many guys you know who have lost mags
in flight. By far most Fords have historically flown with one and the
number one cause of mag issues in my reading of twenty five years of
newsletter back issues has been the mag adaptor loosening up, or the mag
coming loose and getting out of time.
Good luck!

| Subject: | Re: Question about lower fork ends- aluminum struts |
Graham, thanks a bunch for your advice. I'm using the T-craft struts
for both the front and rear. The outside ends of the front struts will
work as is. I'll have to do something at the inside ends -- probably
the same as the Pietenpol plans.

Subject: Re: Pietenpol-List: Question about lower fork ends- aluminum
struts
Chuck,
I used those Taylorcraft adjustable strut ends on my Pietenpol rear
struts. I simply cut them out of the old struts and removed the old weld
bead with a file, and polished them. Then, using the rear T-Craft strut
material cut to the proper length, I installed these adjustable units at
the outboard end with an AN 5 bolt installed vertically through the
minor axis of the streamline tubing. This hole is 90 degrees to the
slotted hole in the adjustable fitting and provides a universal,
self-aligning, strut end similar in function to the strut ends shown on
the plans. I welded teardrop-shaped reinforcement doublers at both ends
of the rear struts. The inboard ends were pinched in a bit to fit over
the fuselage fittings. It was necessary to provide a spacer at the
outboard ends to fill the space between the spar fittings and the
T-Craft adjustable strut ends.
The front struts are similar, but are made from Aeronca front strut
material (I used what was available "at the right price" because I was
poor at the time). For the outboard end, I used 1 inch square tubing
with holes drilled at 90 degrees to provide the self-aligning feature.
Any adjustment can be made by simply cutting and drilling another piece
of square tubing to the desired length. (This method could also be used
for the rear struts.)
Since these struts are open at both ends, it is a good idea to coat
the inside with linseed oil or something similar for corrosion
protection.
This arrangement has worked well for over 41 years and 800+ hours of
fun flying. It also provides flexibility if the wing is moved fore and
aft for CG adjustment by loosening (and, of course, retightening) the
vertical bolts.
Cheers,
Graham Hansen (Pietenpol CF-AUN in Alberta, Canada)

Douwe,
My lightly modified Ford is tuning a Sensenich 76-42 prop at 1960 rpm's static.
I mounted this same prop on my A-65 Taylorcraft and got just shy of 1900 static.
Engine includes an aluminum Winfield head that started life at 7:1 (now 6.7:1),
a modified "B" carb, a log style manifold, SS modern style vales and seats,
inserted rods and mains, full pressure to the mains only, and .080 over "A" pistons.

Quote----Why not put the Saran wrap right on top of the drawn rib and put the
blocks on top of the wrap? That way one piece of Saran wrap for
30-howevermany ribs. C
That is exactly what I did. Just used a new piece for each rib. Cost was maybe
$3. It took maybe 10 seconds to get the jig ready with a new piece.

| Subject: | Re: Ford question |
Welcome to the "new guy" with the Ford question.
I acquired Douwe's Model A engine and put in in my Pietenpol. It turns
1860 static rpm with a 76 x 44 Hegy prop and a Ken Perkins B carb.
Haven't flown it yet. One of the reasons I bought it was to get an A
engine with modern bearing shells vs babbit bearings. I did have an A
engine on it with babbit bearings and a high compression head, and I was
not comfortable with that combination. Does your engine have babbit or
modern bearings?

I've had the pleasure of periodically seeing Mike Perez's progress on h
is Pietenpol and was very impressed with the design idea and the fit and fi
nish of Mike's all-plywood leading edge wrap-around
technique. (the method that Chuck Campbell recently copied) It sure is ref
reshing to see what innovations builders come up with because just when you
think you've seen it all, you probably haven't. EAA's French Valley, CA
Chapter 1279's Pietenpol is like that and has some very clever, simple, and
elegant modifications that simplicate and add lightness!

Just remember a couple of things:
1. It's not going to matter to anyone if you have a hatbox or not in 50 years.
2. The rib jig you spent a month to build will in all likelyhood not be in the
Smithsonian but will set you back a month on your project.
ie. Keep your eye on the donut, not the hole.
Larry (Top Curmudgeon)
@ D.H. You said that you used props to brace your wings for strut measurements.
How many props do you have? Can I borrow a couple?

a little too wide and beefy for the Piet? The Piper's struts seem

Hi All:
Can't find 5/16" 4130 steel for the split gear lugs at the wheel joint as
called for on the split gear plans (1" x 1 1/4" x 5/16" steel)...
I can only find 1/4" 4130. Considering this is stronger steel than the
original called out, am I assuming ya'll would be using the 1/4" 4130
steel... So it's shy a 1/16"... Am I on track?
Sorry if this one is a no brainer, but you know: a guy that doesn't seek
wisdom from others is likely to have a landing gear failure :o)
