Another cable question; in Bingelis books and in AC43 it says that 3/32
copper oval cable sleeves only need to be crimped once. I am using 3/32
cable for the tail brace cables and I know I have seen other Piets with 3/32
tail brace cables but don't remember ever seeing just one crimp on the
copper sleeve.
Is that what those of you using 3/32 cable are doing just one crimp? Tried
doing three last night as a test and it can be done but doesn't look well
and just one crimp makes the ends swell up like you stepped in the middle of
a balloon.

Subject: | Building my first wing rib - the journey begins |
I am starting my first wing rib, and came across the following website-
http://www.2wings.com/m12/faq/wingfaq.htm#04/19/01%20RIB%20CONSTRUCTION,%20GUSSETS,%20GLUE,%20EPOXY,%20STAPLER,%20CLAMP,%20JOINT,%20CLAMPING%20SPAR%20CRUSH%20PLATE
This website is, apparently, is a Builder's area for Pitts Model 12 aircraft. In
reading through I found interesting tidbits of information, but the following
thread really caught my attention. I have cut and pasted it here to make it
easier to read-
"I re-read Cory's post, It does sound as though Cory is gluing the sticks together,
then adding gussets to each side. This would indicate that the sticks are
custom miter fitted on each end, then glued. This is NOT required on any gussetted
aircraft rib. (emphasis mine) The size of the gusset is engineered to
have adequate shear glue strength to transfer the loads and more. I recommend
that the sticks be cut as long as you can to fit the location with 90 deg cuts
on the ends such that one corner of the end of the stick contacts the adjacent
one. Factory Pitts, Stearman and Staggerwing ribs have no inter-stick contact
in places relying on the gussets only. Just like the roof over your head.
This can save bunch of build time. Ribs built in this manner are still stronger
than the required loads." (emphasis mine)
I have three questions-
1. Really? Are 90 cuts on the ends of the braces sufficient over mitered ends?
If that were true, it sure would save me time, but I also know that the Internet
is full of really bad ideas parading as "expert advice". FWIW, I have built
and glued my first rib with the vertical braces mitered to probably within 1/16th.
Am I in overkill, or doing what is the right way to construct?
2. I am thinking about building my wing ribs using Semi-Circle and Quarter-Circle
gussets (I just like the look, although, once built and covered, I won't see
them again). Since they are not the original plans type of gusset, what size
circle did some of you use for your gussets?
3. I heard the instructor in an EAA workshop I attended ask the question, "Are
you building a Timex, or a Rolex?" The point I felt he was making is that you
can build and spend thousands of extra hours fitting tolerences that don't really
make your aircraft any stronger, or you can build it using good practices
and it will be just fine. That is not the same as "The Fisherman" school of aircraft
construction, but yet it is a far cry from building a fine Swiss watch
either. I guess that I am asking for words of advice in this regard as I begin
building. Comments are appreciated.
Thanks to everyone in advance for their advice. I count today in my Builder's Log
as the day I began building my Pietenpol. Everything up until now has been
"research", and I don't think the FAA or anyone else gives two hoots about how
many hours of research I did. They are more interested in what I built, how I
built it, and (at least to me) how many hours I spent building.

Jack, I ordered both ferrules swaging tool from ACS. The ferrules are
3/8-in long and the swager is 1/2-inch wide so the swage is done in just
one crimp. I think the 1 vs 2 vs 3 crimps have reference to the
crimping tool that has a much more narrow 'bite'. I think you are using
much longer ferrules (copper colored vs plated) and a more narrow
crimping tool.

Congratulations on your first wing rib, Terry. Like John, I miter the intercoastals
but I've also read that the 90s are fine. As always, the engineers, A&Ps
and IAs can correct as they see fit - that's my standard disclaimer since I
routinely say dumb things.
I like the "timex vs. rolex" analogy. Unfortunately, it's hard to know what right
looks like when you're starting. That's why you develop your list of trusted
people on this site and seek their advice. You also have your local technical
counselors.
Lemme see: "timex vs. rolex," "pole-vaulting over mouse turds," and, "it ain't
the space shuttle." Not excuses to do sloppy work, but encouragement to do airworthy
work and make progress.

Take a look at the Help for Home Builders section of EAA.org. There are a number
of videos there building a wood wing. All of them cut angles. I believe you
will find most of the folks here also cut angles.
Another advantage to cutting the angles, is you can remove the rib from the jig
without first attaching one side of the gussets. This allowed me to always have
a rib in the jig and two others at the "gusset station". Cleaner and neater.
This also allows you smooth the joints out of the jig, which is much easier.
You can check out my blog at: http://pietenpol-989cb.blogspot.com
On the gussets themselves, I went with the rectangle. I ended up with 4 different
sizes, but the mass majority of them are 1.5" x 1.0". The other sizes were
1.25" x 1.0" - only two of these per side. The other two sizes were specific for
the nose and the tail. Trimmed on the router table. Video on the blog.
Good luck and enjoy the time. If time is real important to save, your going to
be in trouble.

Didn't really answer a couple of your questions - standard disclaimer still applies:
Do as good as you can on the woodwork. I try for 1/32" tolerances. For gusseted
joints I'll go to 1/16". This obviously does not apply if you cut 90 degree
angles on your rib intercoastals.
Ask Gene Rambo about the size of the round gussets on the ribs. TLAR tells me
that 1.25" radius would be ok.

Thanks for everyone's input. Chuck, thanks for the advice about time. Flying is
my job, so staying proficient is not a factor. I look at this as a journey, as
I said. If the destination is the only goal, you will miss the joy of the journey.
I am in no rush.
I also saw the three step wing rib process on the westcoastpiet. com website. I
like the ability to remove the rib from the jig and apply the gussets without
staples or nails. So for that reason alone I think that I will stay with the
mitered braces. I think that I will also stick with the rectangle gussets- easier
to cut, and much less waste.
I will send pictures as I get a little further on the trip! Thanks again to all.

Since it hasn't been mentioned yet, I'll do it now:
Refer to the Bingelis books. They will provide answers to all of your questions.
Attached is a Tony Bingelis sketch showing various joint conditions, all deemed
to be acceptable. If you don't own the set of Bingelis books, get one. If
you have a set, read them. Such a wealth of homebuilt aircraft information.
So, in response to your questions:
1. Yes, 90degree cuts on the ends of the braces are sufficient. They will be slightly
less strong than mitered (less bonding area), but not significantly. Personally,
I prefer mitered joints, but I enjoy woodworking, and take pride in
nice fitting joints, whether anyone else knows about them or not - but that's
just me. I'm not sure what you mean by your statement that your braces have been
"mitered to probably within 1/16th". Do you mean you have 1/16" gaps between
the sticks? Basically the sticks should butt against the top and bottom capstrips.I
would avoid gaps. A disc sander is an invaluable tool in building ribs
(and many other parts) . I use mine ALL the time. Probably less than $100. Get
the biggest size you can find. Mine is 8 inch diameter.
2. I used circular gussets - just liked the look better (but that's me). I made
mine 2" diameter, and cut them into halves and quarters with a thin blade (scroll
saw).
3. Build the way you want to build, and are capable of. Some homebuilt aircraft
have woodwork that looks like fine furniture, and some have woodwork that...
doesn't. Strength will rely on proper techniques, and making sure that glue joints
have proper contact (no gaps between wood pieces that are not filled with
the proper amount of glue). How your aircraft performs will depend largely on
the symmetry and squareness (wherever things are supposed to be square) of your
construction, not how pretty it looks. Always remember "Keep it light". Personally,
I think I'm aiming for a Seiko. A little nicer than a Timex, but much
more reasonably priced than a Rolex.
Lastly, I don't think that the FAA gives a hoot about how many hours you spent
building your plane (unless someone else did more hours on your plane than you
did). What they will care about is whether or not YOU built it.
One rib down, and a bunch more to go. Before you know it you'll have a whole wing's
worth of ribs (unless you get distracted, like another builder, whose name
rhymes with Gary Boothe).

Hi Jack,
thats what bothered me; it looked like some had one crimp but it was much wider.
It could have been just that the 3 crimps blended together.
Both AC43-13 and Bingelis books say just one for 3/32" and 3 for 1/8" sleeves.
Thanks for the pictures,

Not sure that it matters much, but I mitered (sanded) each diagonal and upright
to fit precisely and I honestly don't think it took me any longer to go this
route. I didn't custom fit each part to each assembly, rather I made a set of
"master" parts as I laid out the first rib and used each of these master parts
to make the remaining parts by marking the cut angles on long pieces of capstrip.
Most of us do this anyway (mark lengths) in order to cut our parts to the
correct length, even if we are cutting 90s. So, after I marked my parts I
went to the band saw and rip, rip, rip, rip, rip. Now I've got a stack of parts
with angles marked on each end, so I take them to my disk sander and sand,
sand, sand, sand, sand them to match the markings. It actually went really quick,
and each part was fabricated to the identical dimension as the original master
part. Once I had all these built, which only took me a few work sessions,
I had an entire assembly line set up. Making these parts in batches is a LOT
quicker than making them as you go (marking each piece, walking to the saw
each time, etc.).
I still have all these master parts. They fit perfectly in my jig in the event
that I need to make a repair, or build another Piet later on.
I know that all this isn't necessary, but I just wanted to share the way I did
mine. I would argue that their is some degree of added strength in the increased
contact area. I used the same process with my fuse halves... all the diagonals
and uprights were sanded to match. The fit is snug and leaves no voids.
I think this serves to not only provide more surface area, but also better alignment...
especially when doing a number of the same assemblies, such as ribs.
My $.02
Some of the diagonals cut and sorted.
Gussets ready to go.

Subject: | Re: Building my first wing rib - the journey begins |
Wow! Bill nailed it. We must have been writing at the same time.
I'll agree... the disc sander is an excellent tool. I got mine (6" with 4" belt)
for $100. You can probably do much better than I did by scouring Craigslist.
One more thing I want to agree with... I too enjoy woodworking and take pride in
nicely fitting joints. Not to brag, but I had a 20+ year wood shop instructor
and airplane builder come into my hangar the other night (he has 6 airplanes).
I noticed him looking over my project while I talked to another guy. Later
on I asked him what he thought and he said, "you are doing excellent work".
Yep, I'm glad I've taken a little extra time (emphasis on little) to do my best
work. Is it THE best work? Probably not, but I'm trying.

Since it hasn't been mentioned yet, I'll do it now:
Refer to the Bingelis books. They will provide answers to all of your
questions. Attached is a Tony Bingelis sketch showing various joint
conditions, all deemed to be acceptable. If you don't own the set of
Bingelis books, get one. If you have a set, read them. Such a wealth of
homebuilt aircraft information.
So, in response to your questions:
1. Yes, 90degree cuts on the ends of the braces are sufficient. They will be
slightly less strong than mitered (less bonding area), but not
significantly. Personally, I prefer mitered joints, but I enjoy woodworking,
and take pride in nice fitting joints, whether anyone else knows about them
or not - but that's just me. I'm not sure what you mean by your statement
that your braces have been "mitered to probably within 1/16th". Do you mean
you have 1/16" gaps between the sticks? Basically the sticks should butt
against the top and bottom capstrips.I would avoid gaps. A disc sander is an
invaluable tool in building ribs (and many other parts) . I use mine ALL the
time. Probably less than $100. Get the biggest size you can find. Mine is 8
inch diameter.
2. I used circular gussets - just liked the look better (but that's me). I
made mine 2" diameter, and cut them into halves and quarters with a thin
blade (scroll saw).
3. Build the way you want to build, and are capable of. Some homebuilt
aircraft have woodwork that looks like fine furniture, and some have
woodwork that... doesn't. Strength will rely on proper techniques, and
making sure that glue joints have proper contact (no gaps between wood
pieces that are not filled with the proper amount of glue). How your
aircraft performs will depend largely on the symmetry and squareness
(wherever things are supposed to be square) of your construction, not how
pretty it looks. Always remember "Keep it light". Personally, I think I'm
aiming for a Seiko. A little nicer than a Timex, but much more reasonably
priced than a Rolex.
Lastly, I don't think that the FAA gives a hoot about how many hours you
spent building your plane (unless someone else did more hours on your plane
than you did). What they will care about is whether or not YOU built it.
One rib down, and a bunch more to go. Before you know it you'll have a whole
wing's worth of ribs (unless you get distracted, like another builder, whose
name rhymes with Gary Boothe).
Bill C.

What I meant about time is that, you are right that the FAA doesn't care how many
hours I put into the airplane, as long as it is done right. I only meant a
tally of hours would be meaningful to me.
I appreciate all of the photos as it helps me as I go to get ideas.
I think that the Seiko comparison may be the best goal - not to low end, not too
high end, but built well and built to last.
I do have the Bingelis books, but, frankly, I do not remember that diagram of the
braces and gussets. Maybe it is a different edition. If you can tell me the
book and page, I will go back and search for it.
Back to work.

Terry,
I mitred my rib spacers and cut square/rectangular gussets. Do what Mark did and
cut multiple spacers and gussets. It's really nice to be able to make a rib
a day without having to stop and cut individual pieces.
Building the ribs was great--starting on the project and seeing progress each day.
Every part of it was exciting.

I mitered my rib pieces. If you make them like an assembly line it
doesn't take all that long if you have a power sander. I ended up with
all the individual rib pieces numbered and rubber banded together on my
workbench, so putting together a rib didn't take all that long, maybe an
hour to glue and nail one side. In the long run it doesn't cost much
more to build a Rolex. Its your time, so its up to you. I don't regret
it myself.

If that were true, it sure would save me time, but I also know that the Internet
is full of really bad ideas parading as "expert advice". FWIW, I have built
and glued my first rib with the vertical braces mitered to probably within
1/16th. Am I in overkill, or doing what is the right way to construct?

and it will be just fine. That is not the same as "The Fisherman" school of

either. I guess that I am asking for words of advice in this regard as I begin
building. Comments are appreciated.

Thats how I did my rib pieces and like you it took about 1 hour per rib to
