VERY good info there. Thanks. Seems to me this engine deal is going to take
the most thought and time to figure out.

Members of the list:
I am ready to mount my tail section and need some advice. Can
anyone advise what type or kind of turnbuckles they are using for the
cable connection on the tail section? I have been searching Aircraft
Spruce for adjustable turnbuckles but find the price on the high side.
Don't get me wrong...."no ten dollar head you get a ten dollar
helmet".... guy here. Just wondering the best way to connect the cables
with adjustment. What are most of you all using?

John,
As we all (likely) know, the Air Camper was originally designed around a
Ford Model A engine, which typically produces 40 HP (with a lot of torque at
low RPMs). Many different engines have been attached to the fronts of Air
Campers over the years - some say more different powerplants than any other
aircraft. After WWII, when small Continentals (50 - 65 HP) came on the
scene, many people put them on Pietenpols. In 1967, when B.H. Pietenpol
released the supplemental plans for the Air Camper, he included basic
details for a lengthened fuselage, for use with the lighter Continental or
Corvair engines, as well as motor mounts for both engines. The Corvair that
BHP had used was the earlier 80 HP engine, which likely only produced
somewhere in the range of 60 HP when used on his plane. Builders today
usually use the 95 or 110 HP version of the Corvair, and likely see an
actual output of 80 to 100 HP. Over the years, builders have mounted larger
engines on their Air Campers, but for the most part, the O-200 (100 HP) is
considered the upper limit for this aircraft. Some builders who, by
necessity, need more power, due to payload issues (read: body mass) and have
opted for engines larger than the O-200, such as the O-235. This engine
produces more HP, and will impart more stresses onto the airframe. Anyone
considering using such a powerplant would be wise to have the airframe
analysed by a qualified person, and reinforced as necessary before strapping
themselves in the seat for takeoff. In the UK, the governing bodies
regarding homebuilt aircraft are much more strict, and restrictive than in
the US. Any change (and they really mean ANY) from the plans must be
approved by the LAA. Following is an excerpt from the LAA Type Acceptance
Data Sheet (TADS 047), regarding powerplants to be used on the Air Camper:
"The most popular engine for the Air Camper in the UK is the Continental C90
or 0-200, without starter or alternator to save weight. The Continental A65
has been used but this results in a degraded climb rate and necessitated a
reduction in allowable maximum gross weight, and hence reduced payload.
Lycoming 0-235 engines of 115 and 118 BHP has been used on two examples, but
use of this heavier, more powerful engine necessitates uprating of the
forward fuselage and engine mounting attachment fittings."
Note that they state that the forward fuselage and engine attachment
fittings must be "uprated".
As for explaining about Corvair parts still being manufactured, I think you
just did that.
Don't know if this reply helps you or not, but that's my take on the
situation.

Have you nailed down the materials (thickness, width, length, rod size, etc
) to manufacture the turnbuckles for the tail section? After seeing the pri

Subject: RE: Pietenpol-List: Homemade Turnbuckles
Well, on Saturday, I decided to do a little experimenting with using solid
wire vs. cables, and building a sample homemade turnbuckle.
-
First, the solid wire experimenting:
I made a couple of jigs for bending the solid wire from scrap materials. Th
e design of the jigs was based on information I have gathered over the last
week - thanks to many listers (Santiago, Clif, John and others), and was e
asy to build. Since it was all made from scrap, the cost was nothing. I jus
t happened to have a bit of .080" galvanized fence wire laying around as we
ll. The jig to bend the loop in the end of the wire is pretty straightforwa
rd, and worked well. The jig (if you want to call it that) for bending the
ferrules was even more straightforward - just a piece of rod, ground down t
o approximately the right shape and size, and then driven into a block of h
ardwood. It also worked well. I made up a couple of assemblies to test out
the jigs, and as expected, the second and third attempts were much better t
han the first. I think that after a doing a dozen or so, I would get the te
chnique down to a science (or at least obtain consistant results).
Overall-I was pretty pleased with the finished product (for an amateur)
- looks good, and feels strong.
-
Second, the homemade turnbuckle:
My design for the homemade turnbuckle was based on two things. One was a co
uple of low-resolution photos of the turnbuckles used on the Flitzer biplan
es. And the other was common sense (more or less) based on size and load ca
rrying capacity. I made the ends of the turnbuckle from a couple of strips
of 16ga steel (1/2" x 5"). Because this strip was small, it was possible to
form by hand, and then squeeze in a vise (with the 3/8" rod in place). The
threaded and non-threaded inserts for each end were fabricated from a bit
of 3/8"diameter stainless steel rod (1/2" long), on which I ground down a f
lat section for the bolt to mate with. The threaded portion of the turnbuck
le is a #10-32 allen bolt (hex socket stainless steel machine screw). Like
any hex head bolt, the allen bolt only needs to be rotated 1/6 of a turn (o
r 60=B0)-in order to position the wrench for the next -"crank", but the
allen bolt does not need any clearance around the head for a wrench,
since the wrench fits inside the head. However, this is still a bit tight
the way I built my prototype, and needs a bit of refinement - maybe 1/2" ro
d instead of 3/8". I also need to devise a method to incorporate a safety w
ire, to prevent the tension from releasing.
I put all the parts together and screwed them to a hunk of 2x4, and tighten
ed up the turnbuckle, and it worked!
Photos and description have been posted on mykitplane.com:
-
http://www.mykitplane.com/Planes/buildLogReportDetail.cfm?BuildLogID=1833
&PlaneID=510&FName=Bill&LName=Church&PlaneName=Air%20Camper
-
Note that all of this work was done in my basic garage workshop, with no sp
ecial equipment - just an angle grinder, a hammer, a drill press and a benc
h vise.
-
Before using either of these products (solid wire bracing and homemade turn
buckles) I-would suggest doing some physical testing to determine the act
ual breaking strength(s) based on the actual materials used.

| Subject: | Homemade Turnbuckles |
Ken,
I kind of got sidetracked away from the homemade turnbuckles for a while,
and I've actually been building my tailfeathers. So, the short answer to
your question is "No, I haven't".
Having said that, here's the long answer.
I didn't do any strength calculations, but I have a strong feeling that the
turnbuckles as I made them will be sufficient in strength, but I have yet to
do some real-world pull testing to see what they can safely handle. Before I
do the pull test I wanted to refine the design a bit to make them a bit more
user friendly. That way I'll be testing the proper part, not just something
similar. I still plan to do it, just not right now. If you need an answer
right now, I think just about anyone could make up a set of these in a short
period of time, and then do their own testing using a simple apparatus
(lever and pivot). When I do get around to revising the design and doing the
pull-testing, I'll share the results with the list.
If you want more details about how I made the prototype, let me know.
Bill C.

Hi Gene,
You missed a good time. The grass was green, the mosquitos were
plentiful and hungry, and the Pietenpols were in abundance (at least
more so than the Hatz Biplanes). Here is a picture of the field:
Here is what it looked like from my Pietenpol at 300' AGL:
There was good food, and good camaraderie. And lots of Piet builders
taking pictures and making notes from every flying Pietenpol on the
field (I think there were a total of 14 Piets there):
By the way, on the way home I did go by Jackson, TN to visit Mom.
Coming out of there Monday morning, Flight Service forecast "a few
clouds at 600' ". By the time I got to the Tennessee River at Clifton,
this is what I found:
Shortly after that picture was taken, it walled in all around me and I
was suddenly in full IMC. If I didn't have a Turn & Bank indicator I
don't know what I would have done. As it was, I did a 180 and went back
to Jackson to wait for it to clear up.
Made it back home Tuesday afternoon. In 5 days I put a little over 34
hours on the airplane and flew just over 1900 miles.
Maybe next year we can fly up together with Randy Bush. He was there,
but without his Pietenpol. If I start working on my wife now, I might
be able to get her used to the idea of me flying up again by next July.

what I would have done. As it was, I did a 180 and went back to Jackson to
wait for it to clear up.
Made it back home Tuesday afternoon. In 5 days I put a little over 34 hour
s
on the airplane and flew just over 1900 miles.
Maybe next year we can fly up together with Randy Bush. He was there, but
without his Pietenpol. If I start working on my wife now, I might be able
to
get her used to the idea of me flying up again by next July.

Yeeah, if you're loaded :) Used VHS copies, some up to $50.00, some used bootleg
DVD's, and some expensive PAL format tapes. Note none of the actual sources
are new off the shelf Amazon stock.
For those who might think a Wynne manual is expensive, a $40 movie certainly would
be!
For those of you on my "list" to get one, gonna be about a week before they start
going out. So be on the alert!

| Subject: | Homemade Turnbuckles |
I got to thinking about "hardware store" turnbuckles as a possible alternative
to AN/MS hardware and paged over to McMaster-Carr to snoop. Found some surprises.
For example, let's take the typical 1/8" 7x19 aircraft cable. It's rated
at 2000 lbs. strength. For that, let's pick an AN/MS turnbuckle with AN4 (1/4")
threads, an eye on one end and a fork on the other, roughly 4-1/2" long.
It is rated something a little over 2000 lbs. so it's a good match for that cable.
Searching "the hardware store", we start with open-body aluminum "screen door"
turnbuckles with 1/4" threaded eyes and find that it might be rated a couple of
hundred pounds, obviously due to the aluminum body and the minimal number of
threads on the eyes that engage the body. Move on to galvanized steel and the
strength improves to a couple of hundred pounds, still very affordable. Now
on to the better stuff and we find stainless steel turnbuckles, which are available
in both open and closed body and seem to engage maybe twice as many threads
but are rated no more than 800 lbs. and also have a caution that the working
load should not be exceeded. Can you say "fails rather sharply"?
The cost of hardware store (or nautical/marine, I found) is a lot more attractive
but the strength is just not there without really getting heavy. Is the aircraft
hardware 'overkill' for the working loads? I don't know. I have not run
any sort of analysis to determine the aerodynamic loadings on any of them,
but when we go from 2000 lbs. rating to a couple of hundred, someone had better
do some testing. Same goes for home-made tensioners.
I'm all in favor of better mousetraps, but let's test these things against their
working stresses before we substitute. Those stainless turnbuckles look great
to me and are about 1/3 the price of AN/MS hardware, but I would have to assure
myself that they could handle the flight loads with at least a 2x factor
of safety because my skinny a$$ is worth more than a $10 turnbuckle.

| Subject: | Re: Riblett install |
CG range of the Riblett is very close to the Piet, with a lighter engine up front
I add a slight bungee pull on the forward side of the stick, when the Werner
went on a little back pressure was added. except when full power was applyed
on the Werner a forward pressure was applyed to keep from climbing over 2000
FPM.
I kept the spar the same as Piet as all the fittings don't require a change.
The cord line is higher on the 612, I suspect the angle of incident can be reduced.
I have flown with 5 different engines on the same Piet and do-not change
anything, just to test engines, Now that I am trying the 612 I retry engines .
Don't be surprised to see a great improvement in flight, when using the 612.

Just back from EAA
B & B Specialties is where I buy all my turnbuckles, all aircraft
quality and with any type ends you want, the whole assembly costs
about $10.00 each. Their prices are as little as 1/2 the price others
in the same Fly Market are charging and their prices are the same all
yr. around, not "Show Specials". They don't have a catalog but get
part numbers out of AC/S, call them, order by part number and you'll
get the best price anywhere.
(913) 884-5930
I can't even begin to imagine anyone building a Piet, trying to save a
couple bucks by buying hardware store stuff that they are going to
trust their LIFE with??
Stick with aircraft quality but save by buying from reliable sources
like B&B Specialties.
Amen

Michael:
I have an older edition of WW's that had the drawing for the hub.
There were some other drawings also, but I have filed them away and am
unable to put my hands on them right now. It was always his thing that
if you wanted to make your own he would go out of his way to assist you
and many did and do now. If you are a person who doesn't have access to
a machine shop or the time, he will sell you the parts, but he at least
gives you the choice and nudges you in the direction of doing things
yourself if you are wanting to try but not quite sure. Its not just the
manual you are buying, but the help to the point of holding your hand if
you need it. You probably won't, but it is good to know you have a plan
B every now and then.

Thanks Oscar, a very well written responce. IF I decide to do
the Corvair, I will have to get these mentioned books. I see they are
quite pricy, but what others are available? Machining either hub won't
be an issue, I just wanted to get the best suited part that I could make
that has already been proven. (Rather then make up my own fron scratch.)
Mine will more then likely be 6061-T6 aluminum. Nothing has been
decided...just gathering intel. and you have been of great help.

Mike;
Doesn't look to me like anybody actually answered your question about
the
differences between the two hubs (Pietenpol and Wynne) for the Corvair
conversion, so I'll throw in my two cents' worth and see if I can add
anything.
I have the Pietenpol drawings and the hub sheets are dated November of
1972.
The material indicated for the hub is "aluminum casting". The design
pioneered the use of a "safety shaft" through the center of the hub
into a threaded 3/4" deep bore in the center of the crankshaft end
(nose).
The safety shaft is called out to be a 5" long, 1" dia. 4130 or 4140
steel rod, or 1" dia. by .250" wall 4130 steel tube, threaded 18
threads to the inch. The hub is mounted to the crankshaft flange using
standard
Chevy 11/32" capscrews, 1" long. This requires that the holes in the
hub be bored very deep into it and that a long, thinwall socket be used
to
tighten them. The flange itself has a standard bolt pattern and is
.438"
thick at the prop flange. Overall length is given as 2.875".
I say all of this to contrast this hub to the Wynne hub, which is quite
a bit
beefier but is obviously an adaptation and improvement on Mr.
Pietenpol's
hub. It is 3.5" long with a 1.1" thick prop flange, and is machined
from 2024 aluminum, but William says it could be made from 6061.
William's
design uses a safety shaft that is 6" long because the hub is a bit
heavier, longer, and stouter- and the safety shaft threads 1" into the
crank nose rather than 3/4" as in the Pietenpol. The threads are 14
threads per inch (coarser than the Pietenpol). While the Pietenpol hub
body is
slightly tapered, the Wynne design is straight, again making it beefier.
William's preferred method of mounting to the crank flange is through
the
use of what William calls "hybrid studs", which are threaded with the
Chevy 11/32" on one end and a more standard 3/8-24 thread on the nut end
that holds the hub to the crank flange.
Here's what William says about the Pietenpol hub in his manual, of which
I
have three different editions dating back more than 10 years: "This
method
was pioneered by Bernie [sic] Pietenpol in the early 1960s. Although I
know of
no failures of Bernie's way of doing it, my method is a little different
and
uses different materials, but the concept is the same." He also says,
"The Pietenpol method is brought up for technical reference only. If
you
are building an exact replica of Bernie's engine, his son Don is the
best
source of information on it. Years ago, a number of cast aluminum hubs
were
made to Bernie's drawings. Some of these are still floating around for
sale. These are light duty units suited only to the modest flying done
by
Pietenpols.".
My take-away: make your hub using the Pietenpol or the Wynne drawings,
but
ALWAYS use a safety shaft and ALWAYS use at least 6061 aluminum, NOT any
cast
material. To my non-machinist's eye, the two hubs require about the
same
amount of machine work to produce but the Wynne hub has no tapers to cut
and is
stronger in some important areas, and is a little less than an inch or
so
longer.
