Scott, I commend you for doing the project with the kids. Not sure of you
question but maybe some pictures will help. See here,

Subject: Re: Pietenpol-List: center secting wing ribs
Scott,
There are probably a thousand different ways to do this, but I'll share with
you the sequence I used to help get you thinking about it. First, attach
the metal fitting to the CS spar pieces. Attach the CS spar pieces to the
wing panels. I made up a "skeleton" stand to support the center. The wing
panel ends were sitting on saw horses covered with carpet remnants. By the
way, make sure the wing panels are squared up first by adjusting the
drag/anti-drag cables accordingly. Essentially, you are using the wing
panels as jigs to make sure everything fits together perfectly. Next,
position and epoxy the ribs in place. You will have to chisel away small
portions of the rib vertical truss members to clear the metal fittings.
Next, scribe and cut plywood to fit the wing curve and epoxy in place. I
only applied "butt-rib" plywood to the ribs in-between the spars. I sanded
off all the rib gussets in this area then epoxied the plywood to the side of
the rib, again, in-between the front and rear spars. Next, attach your
leading and trailing edges. Sand and shape everything accordingly. Next,
apply the bottom plywood skin. Now, you can remove wing panels (your jig)
since the bottom skin will keep the CS square. You may want to go ahead and
varnish those areas that will be difficult or next to impossible to varnish
after applying the top plywood skin. Lastly, apply the top plywood skin and
varnish the rest of the CS. I would reference the Tony Bingelis wood
working book for how to glue up the plywood skins. Anyway, this is the
general sequence I used. Oh, and I did not apply plywood to the butt ribs
on the wing panels. I left them open and reinforced the bit ribs with scrap
1/2" by 1/2" spruce pieces. If you want, I can send you some photos
off-line. Hope this helps.

My 7th and 8th grade students have finally finished making the outboard wing

fore and aft sides of the front and rear spar locations. We don't know how
to support the spar locations on the ribs that form the butt joint between
the outer and center wing sections. Those locations are filled with
plywood, steel straps, and pulleys. Those of you that built a 3-piece wing,
how did you build those 4 butt ribs in the spar locations? Thanks, Scott

| Subject: | Re: center secting wing ribs |
Scott,
At first I didn't quite understand your question, but I think I get it now.
The original plans for the ribs do not have any vertical supports at the spar locations.
The full-size rib drawing as supplied by the Pietenpol family incorporates
a single vertical support behind the front spar, and a single vertical
support on the front side of the rear spar. Some builders opt to install vertical
supports on both sides of each spar (4 supports per rib). I believe this is
the route that you have taken. This option does make it more difficult to slide
the ribs over the spars, but if you already have them built that way, it's
too late to suggest not to use supports on both sides.
In any case, since the original design does not have these supports, it is safe
to assume that they are not structurally necessary. Therefore, you will not be
compromising the structural integrity if you notch or remove those vertical
supports as required to clear any interference with metal fittings, etc.
Hope this helps.
Bill C.

Greg's suggestion of leather to protect the bungees is spot on. Another
thing I've done under the anti-chafe stuff (leather/rubber sheet, whatever)
is to take some tapered faucet washers and hog out the hole so it's a
friction fit around a bolt head, then glue them onto all the bolt heads that
could possibly touch a bungee or wear the anti-chafe wrap. Eliminates the
bolt edges which do the damage.
Almost couldn't touch the Piet for the last six months due to work loads,
but it now looks like I can get back onto my daily schedule. I've got to
push hard to get her done here soon, I love building, but I'm really, really
ready to fly!
Happy new years to all!!

Attached is a drawing of the anti chafe cuff.
I purchased the leather from a local saddle shop. It was referred to as
"sole leather" because it is relatively thick, about 1/8". It was very
stiff but leather can be formed easily by soaking it in water for a few
minutes.
It is attached to the bottom of the ash block with a couple of small
screws but the bungees keep it held in place.
Round headed rivets per the original plans instead of threaded fasteners
in this location would most likely eliminate the need for the leather
cuff.

Sir (don't know your name, please advise),
Humbly asking: Are you sure you have chosen the right airplane to build?
My advice to you is: No, do not have this individual cut all your rib piece

#1) It will be very difficult to keep the excess glue away from the routed
-out plywood. If you were to use a traditional flat working surface, one ca
n avoid this by laying wax paper or polyethylene sheet under the gluing sur
face.
#2) You can almost bet that the pre-cut rib pieces will be wrong, and you
will end up making them over again the old fashioned way anyway. This is cu
stom work. Trying to make it into a mass-production operation at this point
will almost surely be very frustrating and disappointing.
#3) Why would you want to give up the experience of doing all these things

blunt, but I see a disaster looming here. If time is of the essence, then m
aybe you might consider some of the other kits available on the market thes
e days, such as Van's RV's or other similar kits? "Insert part A into part
B" type of stuff.
Building a Pietenpol is a journey, not a sprint. If one is worried about wh

should consider a different airplane.
Not trying to discourage, but attempting to be realistic, maybe saving a lo

I want the opinions of the those with the experience but I dont understand
how using a cnc machine to cut pieces allowing precision that cant be obtained
any other way is a disasterous shorcut. Im sure the rest of the response

Dan,
My sentiments exactly. If the idea is to build a plane as fast as
possible, a Pietenpol may not be the wisest choice. When one builds a
plans built plane of this nature, the journey of the build is the
important thing. When I started my journey 8 years ago, I started out
building the ribs. It was relative straight forward, but repetitive. I
had experience building a number of long term projects and I knew if I
could get through the ribs I had it licked. Building the ribs was a Zen
experience. After a hard day at work it was soothing to come home and
put a rib together. I usually did a rib a day. I pulled a rib out of the
fixture and then glued up a new one (about a 45 min process). While the
new rib was curing I went out on the back porch and proceeded to pull
the staples on yesterdays rib. All in all a very satisfying experience.
At the completion of the last rib I had as much enthusiasm as when I
started.
As I said I have been working on my Piet for about 8 years. Most of that
time I was working 2 jobs, so spare time was limited, but I still
managed to do something on it every day, I never worried how long it was
going to take. I knew that I would finish it and that was the only
important thing. Now as I get close to covering and finishing the
project I am starting to feel remorse. The journey has been so much fun,
I don't want it to stop.

Hi
I'm going to be a little less blunt than Dan but he does make some good points.
Oddly enough, the answers to your questions justify his point of view.
First, rib jigs are easy enough to make and the process is sorta fun so you really
don't save much time by having one CNCed. The plywood jig, as Dan said would
be a glue bucket. It would make an interesting wall plaque, though.
Second, you CAN save a little bit of time by doing all the individual rib cap strip
pieces for each place on the mold at one time. I made a "master" set of
the pieces for MY jig and then duplicated 30 some of them using a miter saw and
stop blocks. Took maybe 30 minutes to make a pile of each of the pieces. Maybe
2 days total to generate 12 piles of little pieces. You'd probably spend
at least that amount of time doing all the programming for the CNC machine.
Net saving -- zero. Net pride -- +1. That way, I could go out to the workshop
each night, take a rib out of the jig, "reload" the jig with new pieces, put
gussets on the one fresh out of the jig to complete it and be back before Jeopardy
was over. You can do two ribs per day at the most anyway so it's not what
you call mass production.
Third, and this really gets to the core of Dan's issue, you'll find out pretty
quickly if you like the idea of doing a plans built airplane. If you find you
actually like doing ribs, most of the other tasks involved in building a Pietenpol
are a similar learning experience. The tasks become a little more complex
and the materials, specifically steel and fabric, present their own challenges
but the skills are not difficult to learn and there are LOTS of resources
available.
Worst case is you find it isn't your cup of tea and it's time to look for a nice
old Cherokee. (Mine, incidentally, is for sale) The cost for wood for the
ribs is a pretty small price to pay to find out you don't have the interest or
willingness to invest the time. You can always give the ribs to someone on this
list and keep one to hang on the wall.
Best case is you get addicted to the idea of creating something with your own hands
and come to Brodhead in a couple of years.
You'll never know unless you try.

Ribs, BTDT... Almost complete on my 2nd wing.
Here is my method..
Layout the rib outline on a flat wood platform.
make a bunch of small blocks and screw them up against the outside of the r
ib outline.
on the inside more blocks allowing for the 1/4- capstrip, except leave ma
ybe 1/16 or 1/8 clearance
Then use disassemble spring clothespins for wedges to force the capstrip ag
ainst the outside blocks.
I tried to cut capstrips myself,gave up, ordered them from ACS.
Make 2 x 4 blocks for the front curve, soak strips o/nite in water
clamp- them in the blocks 24 hrs, no need to steam.
Dave- NX1QZ- I also deleted the under camber.

As Dan said previously, using a CNC cut sheet of plywood for the rib jig
has issues. The best method is to follow the standard procedure for
building the jig. Buy and follow the Tony Bengelis/EAA books. Building
an aircraft, even one as simple as a Pietenpol, is a complex process. If
you try and reinvent the wheel at this early stage, you will most likely
never finish.

I have to agree with Dan. For some reason, nearly everybody who starts
building a Pietenpol comes in with the idea that there is some way he/she
can "improve" the design or speed up the build process. Many decide that
what this airplane needs is for the plans to be done in CAD, either 2-D or
3-D. Some try to automate the rib building process. Others decide that it
is easier to make the fuselage oversize than to try and re-size themselves.
As someone once said "You can modify the Pietenpol plans and build a good
airplane, or you can build it exactly to the plans and build a great one."
I made a number of changes to the plans on mine, and most of them I regret.
The Pietenpols I have flown that were built closest to the plans are those
that fly the very best.
It is GOOD to think about such modifications (to the design or the building
process), but it is even better to not spend much time on them. For
example, the ribs take 30 days to build - 1 rib per day. If you were to cut
all the parts out ahead of time you can probably cut that down to 29 days.
Unless you have multiple jigs, it still takes about a day for the glue to
cure so you can pop the rib out of the jig. When I built mine, I would glue
up a rib in the jig, and then cut out the parts for tomorrow's rib while it
was curing. The next day, I would pop the rig out, glue the gussets on the
back side, put all the freshly cut pieces for the next rib in the jig and
glue it up. Total working time per rib, about 3 hours. If all the parts
were precut, it would save 2 hours of cutting parts each night while the
previous rib was curing. Total time saved would be zero because the
limiting factor is still jig time for curing the glue (note - I used
Resorcinol, not T-88, so curing times may vary a bit).
If you want your friend to cut a rib jig out of some material that is inert
to epoxy, such as Delrin or ultra high molecular weight polyethylene, you
could use such a jig to advantage, as long as your shop is held at a
constant temperature. The nice thing about a wooden rib built in a wooden
jig is that the linear coefficient of thermal expansion as well as the
shrinkage or expansion with changes in humidity is the same between the wood
of the rib and the jig. Not so for a plastic jig.
Don't get discouraged by all this talk. Just get the plans, build your rib
jig, and start making sawdust. BTW, if you haven't got them yet, buy the
four Tony Bingelis books (The Sportplane Builder, Sportplane Construction
Techniques, Firewall Forward and Tony Bingelis on Engines), and READ them
(they don't do you any good sitting unread on your bookshelf). You can get
all four from the EAA for about $80, and just about any question you have
about how to build an airplane can be found in the pages of those books.
What is your name and where are you building your Pietenpol? If you notice,
many of us that have flying Pietenpols list not only our name and location,
but our N-Number so you can identify us by our airplanes at Brodhead. You
ARE planning to visit Brodhead, aren't you? It is the best place to get any
Pietenpol related question answered - usually several different ways.

Since you are asking about having a friend possibly make up the rib jig and
cap strips, I conclude the wood that is on it's way is not cut to size. Yo
u may already know; you can buy cap strip cut to final dimensions, you just
need to cut the length. If cutting up bulk wood is not your thing, then yo
ur friend may be a big help...regardless if he uses CNC or a hand saw.-

I recommend-building your plane however it suits you and your situation b
est. If friends-are available and have the skills, tools and means to hel
p out, I would consider that a blessing.

My turn! :-) If you want to use that ply contraption,
great, but you will need to drill at least 2" holes
under every glue joint so the glue falls through
without touching anything. Also these holes will be
necessary for popping the rib out of the jig.
Now, having said that, personaly I would still use
the flat board covered in saran wrap with blocks
and cams screwed to it. Why? Well, the excess glue
that does drip down hits the saran and flattens out.
When you turn the rib over to gusset the other side
you now have even more gluing surface than the first
side. Right? So what happens to that glue in your
fancy jig with holes in it? Why, it drips this big blob
you have to cut off before glueing down that backside gusset! Trust me,
you can clean away excess glue
all you want but the next day there will still be a blob!

A CNC rib jig is not going to cut 2 years off your build time. Simplicate,
don't complicate. You will make far quicker progress by committing to
working on the project every day (using tried and true methods) than by
trying to invent new ways to build the wheel....
