No it's not worthless weight. The strength is
commenserately more per square inch. Therefore
you would resize the parts to bring the weight
and strength in line with spruce.
Also you can go to the link I've provided previously
and compare the weights and strengths for yourself.

OK, check this out the next time you visit the Bat cave to retrieve
the sacred papers.
I believe I heard correctly that Bernard P. and Albert E. were the
best of buddies. After all, minds like those would find little to
discuss with mere mortals such as ourselves. Anyway, the story goes
that Bernard and Albert were out flying one day and Bernard mentions
that it would be so much less butt clenching if a particular fence was
to be removed giving access to a second field and making their runway
longer. Albert's little light bulb lights up - he says "Ach! Of course.
A unified field theory." And, the rest is history.

Yes. With anything you use it's not what you use
but HOW you use it.
Something else to ponder; ALL THE REST OF
THE DAMN PLANE IS WOOD!
Just remember, those struts attach to the wing spars.
Those wing spars support the entire plane 3000' in
the air ( including YOU ).
And what are they made of??

Clif,
In all fairness, and with due respect, the weight WILL be worthless unless you
go through the engineering required to re-design the entire structure to suit
Douglas fir (I know, I know, that's what you just said).
I should have been more specific and clarified that DF is stronger, and that all
members could be resized to accommodate this. According to this EAA wood book
I'm reading, DF is 23% stronger, and 26% heavier than spruce. If the entire
airframe was redesigned to accommodate the DF, there would only be a 3% increase
in weight of the structure.
My hunch is that someone who builds their entire airframe from DF will not do the
requisite engineering, and their airplane will, in fact, be unnecessarily heavier
than an identical example built from spruce. The 23% increased strength
isn't needed, as has been proven time and again over the last 80+ years.
Now, let's assume all the wood in the completed airframe weighs 200 pounds (that's
a total guess). A 26% increase would cost you 52 pounds. That's roughly
a 7.5% increase in empty weight (assuming a 700lb empty weight), or 8.6 gallons
of 100LL. That's 52 pounds of people, stuff, or gas that you can no longer
haul around.
In my mind, everything is a compromise. Without a complete reengineering, substituting
DF for spruce compromises useful load and performance while unnecessarily
increasing strength. It's a lose-meh...
All that's saved is money.

All that may be true, but its still possible to build a light DF Piet.
Mine doesn't have a splinter of Spruce and came in at 692 empty. This
subject has been argued on the list as much as the Continental/Corvair
issue. It all comes down to the compromise between availability, price,
and how much the builder weighs. If you are close to the "average" FAA
pilot weight of 170, Douglas Fir may be for you. I guess my point is
you have to look at all the options and make your own choice.

I doubt they give you a choice, but you can ask. The wood I received was very nice,
tight, straight grain. Pay attention to how you orient the grain as you make
your pieces for the various parts.

Subject: | Rib - about to cut wood - spar perpendicular chord line? |
My first post - got "ruined" at Brodhead when Dale McCleskey gave me a ride in
his Piet. Never underestimate the [positive] impact of a small act of kindness!
My Sonex project (scratch build #1465) is now wondering why wood and epoxy are
showing up in the shop. Not abandoning the Sonex, just figured that a little
variety might get me through builders' block.
Just starting on the Pientenpol ribs and would like some advice regarding whether
to tilt the spars 1.5 degrees forward or build them perpendicular to the chord
line.
I purchased Bill Rewey's 612 Riblett plott. I replotted using the original Riblett
offsets (incidentally the computer plot was identical to Bill's hand drawn
layout). When I went to lay out the spars and verticals I noticed that Bill's
were canted 1.5 degrees forward. (see attached picture - i.e. the spars are
not perpendicular to the chord line, instead they form an 88.5 degree angle
to the chord line).
Reading through the archives I've learned that the angle of incidence of the wing
is supposed to be 2 degrees and that it is common to make the rear cabanes
1" shorter to achieve the 2 degree angle of incidence.
Drawing on this logic, if I build the wing as per Bill's drawing, I'd make the
rear cabanes 0.25" shorter to achieve the 2 degree angle of incidence (i.e. if
2 degrees requires a 1" shorter rear cabane, then if the wing had 1.5 degrees
built in, then only 25% or 0.25" adjustment to the rear cabane is necessary.
So the question: should I build the rib so the spars are: (a) perpendicular to
the chord line, (b) 88.5 degrees to the chord line, or (c) 88.0 degrees to the
chord line?
Here's the archive research if anyone is interested:
Googled (site:forums.matronics.com pietenpol "chord line")
which returned the following link:

The challenge with giving a ride to Mark is he is a tall mountain of a man (and
handsome, too!). I was afraid he'd knock the fuel fitting off the bottom of
the wing tank with his head - not good for any of us. Billy's sized a little
more practically for a plans-built Piet front seat.
You'll be flying your own soon enough, Mark. You got Theresa varnishing and that

You can use the Search facility to search the Pietenpol-List forum for "Riblett
incidence" (DON'T include the double quotation marks but DO select the "Search
for all terms" radio button) and you'll get a fairly relevant list of threads
to read.
At first glance there is a lot of confusing information regarding how to set the
incidence for a Riblett 612. I don't have time to sort it all out and give an
opinion at this time, but it appears at least possible that the angle of incidence
relative to the upper longerons will come out OK provided that the spars
rest on the rib bottom capstrips:

Unrelated, but when I re-read the opening sentences from my post this morning,
they didn't make much sense! Would have been better stated as:
This is my first post. I'm in the midst of scratch building a Sonex, but I got
"ruined" at Brodhead. Dale McCleskey gave me a ride in his Piet and now I'm
embarking on a Piet project. Never underestimate the [positive] impact of a small
act of kindness!
Hopefully that opening makes a little more sense!
Related to the Rib - if anyone has a full size layout handy, just check the angle
between the chord line and the spar and let me know if it is a right angle
or a slightly acute (i.e. 88.0 degrees or 88.5 degrees) tilted toward the front
of the wing. My guess is that the full-size original pientenpol layout will
not be a right angle.

Saturday, Hartford was the sight of the pig roast around the birthday of

goat, a small boy and the side of the house. If you were to stay safe, you
needed to stand where the cone was.
After the carpet bombing, we headed back over to the house and there was
Amy. I had not seen her all year so we caught up and I found out she was
leaving for school the next day. I said if she wanted to fly the Piet then
we would have to go back now. She said okay and off we went.

Hi Gary,
That thing is really coming along. Your getting close to
the 90% done-50% to go stage. Stuff gets done in this
stage but it's not as noticable as some big thing--like a
fuselage!
The surfaces that the fittings cover is flat and on the bottom
ones there is a filler glued to the strut to make up the
distance between the fuselage brackets.
Essentially I rounded the front and rear of the strut with the
blank square then shaped them to get that oldtime profile.
Then rounded in the narrowed areas near the ends.
Since there's two bolts at each end I made up a flat bracket
of 0.063 steel to connect them on each side of the strut.
I can't seem to figure out how to get to a specific message
number in the list search. I finally found the one where I
laid out the strength characteristics I used for my calculations.
In this case it was for the outer wing struts but the same
process is good for the cabanes and they don't have much
force on them. I'm going to have to do up all these calculations
and KEEP them somewhere! They always disappear after I
satisfy myself all is OK.
Here it is;
"Spruce has a tensile strength of 6700 lb/square inch.
For the sake of argument lets say a strut is 1" X 3 1/2". With
streamlining the area should be 2/3 of the square area, or 2.3 square inch.
There are four struts or 5.2 square inches. Thats 34840 lbs( yes I know
ththe front ones take the majority of the load) .Dividing on the assuption
of equal load on a 1200 lb AC we get 29 g! How much less if properly
calculated? 25 g? 20 g? Is this adequate?
There's a bolt at each end. The strength here is based on how much force
required to pull a plug of wood out by the bolt. That plug has two faces,
the square area of which is the width of the strut times the distance from
the end to the bolt. If the strut is 1" thick and the bolt is 1" from the
end then you have two faces each 1" square or two square inches. The "shear
parallel to the grain" is 1120 lb per square inch. So we have a strength
here of 2240 lb. Four struts so thats a total of 8960 lb. That's still over
7 g. If we added another such bolt we have 14 g capacity. Taking into
account the higher front strut stress I'd bet we still have at least 10 g
to play with.
And this is for plain, solid spruce, no plywood, no laminated straps or
embedded tubing or anything else to complicate matters.
You can add a little more strength by using Western Hemlock or Doug Fir but
not much. "

Hi Cliff,
My cabanes are similar to yours. Considering the taper at the ends, I am
curious to see just how you handled the fittings, and if you had any ideas
on the subject. In retrospect, it would have been easier to leave the ends a
little more 'block' shaped, but that would detract from the general
appearance.
Here's a picture of my progress to date.
Any comments about the fittings would be most appreciated, and some
close-ups. Hope to see you at Brodhead.

I think if a Piet were built with rebar reinforced kevlar, it wouldn't be an AIRplane
any more, but a a groundplane. It'd be so heavy that it wouldn't fly.
And it would take FOREVER to taxi to Brodhead if you live more than 5-10 miles
out... But at the same time, Jack Phillips might be more inclined to use a
Corvair if Piets never got airborne... crankshaft failures would only be mere
inconveniences at 0' AGL.
Back on topic, I plan to use wood cabanes and lift struts on mine, when I get to
that stage (which is going to be a LONG time).
DO NOT archive!
