| Subject: | Building Wing Ribs |
I'm just about to finish up building all my wing ribs. I've accomplished the FAA
goal of learning a lot while doing this. Here are a few observations for those
who have not yet reached this milepost:
I steamed, rather than soaked, my capstrips for bending. While many have used the
soaking technique with success, my woodworking background makes me uncomfortable
soaking already dry wood. The heat, not the moisture is what allows the
easy bending of the strip. I already had a steam box (3/4 ply, 8x8x36) from another
old project. You could easily make your own & hook up the steam from a kettle
and hotplate. One end of the box was closed, and the other sealed with a
towel while the strips were steaming for about 30 min.
Somewhere in the 'instructions' I recall reading of the 'buggy whip' test. I have
used this test with good results. Grab one end of a long, properly dimensioned
capstrip and whip it violently once or twice. I found that about 1/3 of the
strips would snap off in my hand. I cut these shattered pieces up later for
use as the shorter cross bracing. The stout pieces that passed the test were
the ones I used for the long, outer capstrips of my ribs.
I used the 2-inch hole saw technique for cutting all the gussets. A cheap set of
hardware store metal hand shears is all that is needed for cutting them all
to final size and shape.
The handiest tool I bought for the Piet project has been a Harbor Freight 12-inch
benchtop disc sander. The heavy cast-iron plate and med-grit paper makes short
work of getting a precise final fit to all those capstrip cross braces (fuselage
pieces, too).
I cut the bending/drying jig to the same profile as the finished rib upper surface.
When removing the steamed capstrips from the jig after drying overnight,
there was a small bit of springback that did not worry me. I found a few cases
where the dried capstrip had broken at the severest part of the curve during
drying. In some other cases, the strip broke when bending it into my assembly
jig, in spite of the steaming and pre-bending. Not to worry. These became more
short cross-bracing.
In one case, after steaming, drying, and assembly of the rib, I found the capstrip
split at the severest curve the next morning after the T-88 had cured. I did
a T-88 repair on this part since it will be under that 9-inch gusset the length
of the leading edge.
Maybe others will chime in this threadwith good techniques of their own.

Nice write-up, Lorenzo. You might find yourself in demand at Brodhead to
teach a rib-building class.

It typically takes between 1800 and 2500 hours of work to build a Pietenpol.
When I built mine, I kept a detailed log and put a total of 2,465 hours into
the build. I was working at a full time job and found that I could
realistically put in about 10 hours a week on the Pietenpol - a couple hours
a night Monday through Thursday, and then another couple hours sometime
during the weekend. At such a pace, it takes between 3 and 7 years (it took
me 8 years, but for a 2 year stretch while I was designing and building my
house, I did no work at all on the airplane) to build one. If you can work
full time on the airplane (40+ hours a week), building it in a year or so is
a possibility.
Don't be in a big hurry to finish it. The building process is highly
enjoyable. As the saying goes, take time to "Stop and smell the Sawdust".

You are correct about the building being enjoyable. I do very much enjoy it
. If I wanted something to fly right now=2C it would be best (and probably
cheaper) to just buy something - maybe a flying Piet=2C an Aeronca=2C or Cu
b. But I am already anxious to see this project fly. When I'm done I will p
robably start on another plane - perhaps an RV to actually go somewhere. In
the meantime=2C the Piet is a pleasure=2C and I'm sure it will be a pleasu
re to fly. My local airport has never seen anything like it.
I'm targeting about 1000 hours of total build time. Actual shop time. I don
't count all those hours reading Uncle Tony's books & widow shopping throug
h the Aircraft Spruce catalog. I try to do something every day. Weekends ar
e where I can really get involved. Since starting in Feb of this year=2C I'
ve got the tail pieces and fuselage done. I should have the wings done in a
nother month. Another month to get all the fittings=2C landing gear=2C and
assembly done. Engine installation and fabric over the winter. Flying by ea
rly summer next year. Maybe optimistic=2C but we'll see.

| Subject: | Carb choice for ford |
I need a little advice here.. In choosing a possible carb for my Jeep engine
powered piet, I tried a universal four cyl carb made years ago for tractors
fork lifts ect. It was brand new in the box, but it was very heavy and bulky.
Then I did a little research and it seemed some ford powered piets use the
Tillotson X Carb. So I bought one of them. It is small and light but what
concerns me is the small flimsy throttle arm. It seems like a very weak link
to risk your life on a piece of pot metal not much thicker than a kitchen match
with a little ball end to attatch your cable to. What other options should
I look at?

How did you come up with an extra set of ribs? I am building a steel fuselage
too. I copied Aerojake and I am putting a door in the front seat. Have not figured
out the hinge yet. Also added about 7inches to the front seat area. I have
a wooden fuselage at the shop I am going to build the steel gear and brackets
for. If my friend puts the engine he wants on it, it will be something neat.
He wants to put a Donavan Model D engine in it. The model D is a copy of a model
A that is made to race engine specs. It is made of aluminum with a chevy 350
bearings and billet crank, forged rods and pistons. The ports are fashioned
on 350 ports. It is expensive but still cheaper than a new plane engine.
