Be careful with old J3 lift struts. Original struts were open to the atmosphere.
Moisture condensed inside, ran down the tube, and collected in the bottom, causing
them to rot out from the inside out. There's been AD out on these for a
good number of years now. I don't remember all the details, but the AD requires
an expensive inspection and rolling them with hot oil on a relatively frequent
basis. A good lot of the Cub people have replaced theirs with sealed struts
(from Univair, normally), which eliminates the removal & inspection requirement
of the AD. I had the ones in my Cub replaced maybe 5 years ago.
Consequent to all this, there is a glut of old, possibly unsafe J3 lift struts
on the market. A lot of folks are trying to take some of the sting out of having
to spring $400 each times four for the new ones by selling the old ones. If
your intentions are to shorten them, you'll have to open them up anyway, and
if the upper part is clean and you can re-fabricate the lower part, then you can
put a nice set of struts together for a steal. But if you need them full-length,
buyer beware.
Can somebody here tell us if the J-3 struts are longer than the Piet requires,
and by how much?

J-3 struts are longer than req'd by our Pietenpols--not sure by how much,
but enough to cut off the bottom foot or so I believe--maybe more.
and use them.

Cool!
Then we're in. I think my old struts are still in the mailing tube dumped out behind
the hangar belonging to the guy who put the new ones in for me. If they're
only 84", then I could hack them up the next time I'm in Florida to get them
under the 8' regular shipping limit and send them home.

Any way you measure it, it's cheaper and wiser to weld up your own struts.
Reasons: Struts are such a critical part of the plane, used struts have
rust inside them (always do, always will, just a matter of how much), many
AD's have been issued on Piper struts over the last 40 years requiring
fabric-type punch testing of the lower ends of struts and/or Xray analysis,
each homebuilt is ever so slightly different therefore you custom size your
struts to your airplane. They are not difficult to weld up or have welded.
4130 streamline tube is kinda expensive, round tube 4130 is cheap and
considering the low and slow nature of the Piete design, this an option.
You can always put steamline fairing around the round tube. Newly
constructed custom sized struts will last your lifetime and you won't have
to worry about one more thing on your homebuilt.

Gene,
I think BHP's idea for the landing gear/strut attach point isn't so
much about whether or not the struts are parallel but about where to
attach the back of the front seat. A quick look inside the cockpit of
different Piets will tell you if the builder left everything as located
on the plans or if he moved the ash piece back. If the ash piece is
moved back to the center of the cluster the plywood back of the front
seat will come down and sit on top of the ash piece. If the ash piece
is left 'as is' in the plans the seat back will glue to the back side of
it. I went so far as to bevel that back edge to get a good glue joint.
With this setup the seat back is now attached to the top cross member,
the front edges of the fuselage side uprights and the back edge of the
ash cross piece. (got all that!?) All very good joints. I feel this is
important because the seat back is a stuctural member offering cross
sectional strength as well as floor stiffness.
We all know there are some areas of the plans that are left to the
imagination, but when you think about a 16/17 year old Orrin Hoopman
taking measurements and drawing the parts and pieces, after Mr.
Pietenpol made them, so that others could understand them, it's really
amazing they are as complete and as accurate as they are! If you
question anything on the plans and are thinking about changing it, make
sure you really consider why he did it that way. Just about every time
you'll figure out and realize he was an exceptional 'eyeball engineer'!

Today I successfully completed the first taxi test of Pietenpol N491RH. It has
been a long haul to get to this point. I bought the plans from Bernie Pietenpol
in August of 1969, just after I got home from the EAA Convention at Rockford.
There is some wood in the plane that I cut that month. Various moves, job
responsibilities, divorce, travel, etc. have caused starts and stops in the
project over the years, but I am finally ready to call for inspection for an Airworthyness
Certificate. I picked the screen name slowbilder (misspelling intentional)
for this listserve as appropriately reflecting the 37 years it has
taken to get to this point.
The plane is built from the 1933 plans. The tailwheel installation is my own design.
I did not move the wing back, but extended the engine mount. The CG came
out within the envelope. With the stock landing gear it is of course very
light on the tailwheel. I am using a Continental C-75-12 for power. It has
the generator and starter. The battery is mounted on the front of the firewall.
The airframe was completed before we had routine access to the internet (Maybe
even before the internet existed.) and I rarely had contact with other Piet builders,
so I spent lots of nights working out the answers to questions that we
can get on-line now in a short time. It is rewarding to see that most of the
solutions I am seeing in this forum are the same that I came up with. I appreciate
the answers to my questions I have received from you folks out there.
Ill keep you posted as I pass further milestones.

Gene,
If the plans have a different distance at the bottom of the struts than at the
top, then they would not be parallel. I followed the plans very closely in this
area. My struts must not be parallel then. However, when I set up the wing,
to ensure my wing was where I wanted it to be, I built a fixture to hold the
wing above the fuselage and made the struts to length.

Subject: | Re: Parallel struts and Gene's question |
Gene,
This summer at the Brodhead Piet fly-in, I measured a variety of completed Piet
wing strut attachment distances. I have found that of all the strut distances
that I measured, every Piet had non parallel struts (I did not measure all
the Piets). As I recall, the lower dimension was typically shorter than the
top from about 1/2" to 1". I also noticed that I could not identify the out of
parallel by eye. My only drive to measure the attachment distances was to see
if the out of parallelness of my project (not complete yet) would be detected
by the eye and look poorly.
My apologies to the group for not being able to join the discussion sooner, as
I was having trouble sending e-mail these past three days or so. My son fixed
me up this evening.
I would also like to thank those who offered advice on bending flat steel. I
ended up buying a $26 bench top break from Harbor Freight which worked great
for my needs.
Thank you,
john

All of this is well and good, and I already know these things. My
question remains, will someone PLEASE just tell me if their struts are parallel
and whether they were conscious of that fact during construction.
So far, unless someone can tell me otherwise, it looks like no one has even considered
the question or noticed whether the struts were parallel or not while
building their airplanes.

--> Pietenpol-List message posted by: "Don Emch" <EmchAir@aol.com>
Gene,
I think BHP's idea for the landing gear/strut attach point isn't so much about
whether or not the struts are parallel but about where to attach the back of the
front seat. A quick look inside the cockpit of different Piets will tell you
if the builder left everything as located on the plans or if he moved the ash
piece back. If the ash piece is moved back to the center of the cluster the
plywood back of the front seat will come down and sit on top of the ash piece.
If the ash piece is left 'as is' in the plans the seat back will glue to the
back side of it. I went so far as to bevel that back edge to get a good glue
joint. With this setup the seat back is now attached to the top cross member,
the front edges of the fuselage side uprights and the back edge of the ash cross
piece. (got all that!?) All very good joints. I feel this is important because
the seat back is a stuctural member offering cross sectional strength as
well as floor stiffness.
We all know there are some areas of the plans that are left to the imagination,
but when you think about a 16/17 year old Orrin Hoopman taking measurements and
drawing the parts and pieces, after Mr. Pietenpol made them, so that others
could understand them, it's really amazing they are as complete and as accurate
as they are! If you question anything on the plans and are thinking about
changing it, make sure you really consider why he did it that way. Just about
every time you'll figure out and realize he was an exceptional 'eyeball engineer'!

They are longer and by over a foot. I bought 4 at Oshkosh a couple yrs back
for $25 ea. They are not open on the ends though, but sealed both ends.
Still I want to inspect them, hopefully through the fork hole in the bottom
and if they are bad then cut off the bottom where they had the problems and
if all right them cut off the top end.

> Be careful with old J3 lift struts. Original struts were open to the
atmosphere. Moisture condensed inside, ran down the tube, and collected in
the bottom, causing them to rot out from the inside out. There's been AD out
on these for a good number of years now. I don't remember all the details,
but the AD requires an expensive inspection and rolling them with hot oil on
a relatively frequent basis. A good lot of the Cub people have replaced
theirs with sealed struts (from Univair, normally), which eliminates the
removal & inspection requirement of the AD. I had the ones in my Cub
replaced maybe 5 years ago.

struts on the market. A lot of folks are trying to take some of the sting
out of having to spring $400 each times four for the new ones by selling the
old ones. If your intentions are to shorten them, you'll have to open them
up anyway, and if the upper part is clean and you can re-fabricate the lower
part, then you can put a nice set of struts together for a steal. But if you
need them full-length, buyer beware.

I hope everyone understands I was just being faucisious in my statement.
This is truely a very unfortunte event. I'm just glad the pilot is alright

I cannot reply to any message on either of the two

At the bottom of each page it says "error on page" but
I think that is maybe something not "Yahoo related".
Any advice?

Congratulations Bob,
I just taxied for the first time the GN-1 I bought and only had to reinstall the
wings and rigging and it was way cool. I can only imagine it will be a whole
other level when I taxi the Piet I'm building.
Any chance of a picture?
