Glue a patch of leather on to the fabric, and then cover it with another

I have a drawing that I wanted to present to the group, but my
scanner/printer is not working properly. So I will have to try to describe
the step in words rather than the picture. I'll try not to use 1000 words.
:>)
Under each seat sticking out of the fuselage is a retractable (telescoping)
step. Each step consists of the following. The lelft side of the step is
fastened to the lower. left longeron. Five inches into the fuselage is a 1X
1 X 5 block, parallel with the longeron, which supports the inner end of the
step. The outside of the step consists of a piece of 3/4 dia tubing, .035
wall thickness, 6-1/8 inch long. The tubing is held to the longeron and
5-inch block with metal straps. Inside the outer tubing is a piece of 5/8
dia .035 wall tubing 11-3/8 inches long (plus a little to run an AN3 bolt
with nut which acts as a stop.) On the left end of the smaller tube is
welded a round plate 1-3/4 inch dia. (which acts as a stop to keep your foot
from sliding off in the extended mode and a asstop at the fabric line in the
retracted mode.) Thus in the extended mode you would have about a 5-1/2
inch step; in the retracted mode the round disk would be flat against the
fabric of the fuselage. Hope that is clear -- I can't send a picture.

Mark,
As you know, I'm not flying yet, but mine are laminated hickory. By ripping the
boards and turning the grain pattern, you only need to find boards with close,
straight grain. At home, I have a very thoughtful response from Cliff Dawson,

Chuck,
I like your idea, however, I am neither a graphic arts specialist nor an engineer
as well. But I was thinking 2 additions-
1. Could you put a short L-shaped notch on the inside end of the larger diameter
pipe, so you could pull the inner pipe with the AN Bolt screwed into it into
the notch and turn it slightly to lock the step in place as it is in the extended
position.
2. Could you somehow attach a small spring to the end of the pipe to give it a
little tension in order to keep it retracted in flight. That way it would not
possibly keep vibrating out into the open position. There is enough drag already
without adding a pipe sticking out, even if it is small.
Just my $.02, but I definitely like your idea.

Don't know if anyone mentioned it but after you've rigged the control cables and
BEFORE you cover, measure the exact spot where they would go through with reference
to some fuselage landmarks. That way, you can use the soldering iron
technique and make the minimum hole size and help "control" chafe. No 6 inch
teardrop patches covering TLAR mistakes.

Subject: | Venting fuel tanks |
All,
We have started planning our fuel system and have a few questions about
venting. At this point all we have done is mock up the tanks with foam
board. Here is a basic description of the fuel system as planned: We are
welding up a 7-gallon aluminum header tank that will feed a C-0200. The
header tank will be replenished from a 12-gallon center section tank. There
will be a fuel shut off valve between the header tank and the gascolator
with the valve stem extended to reach the pilot. There will be a shut off
valve in-line, within pilot reach, between the center section tank and the
header tank. During an engine out landing, onto an unfriendly field,
forrest, etc, I want to be able to shut off both tanks as close to the tanks
as possible to protect against fuel flowing from a broken line.
For now I am thinking just a simple stick type float gauge on the header
tank. The gauge should not begin to move until the center section is empty.
With the possible exception of Broadhead I doubt legs will be flown longer
than the center section will provide for. For those of you flying with this
type gauge a question: does the pressure from the slipstream prevent them
from falling correctly? Would you use this type of gauge again? (Yes, I know
time and power settings are the only reliable way to calculate fuel
remaining but a gauge is still nice)
I have noticed a number of Piets with vented caps, a number with vents
positioned here and there, and number that appear to have both. I want to
vent each tank separately to allow the header tank to continue to work if
the center section fuel valve is closed for whatever reason. So, where and
how to vent are the questions. Thoughts?
Thanks,
Don

Subject: | Re: Venting fuel tanks |
Don:
Chuck Gantzer from Wichita has a similar system that he described to me
early on. He stated that the fuel from the center section tank would
overfill the header tank and leak out the vent which just happened to be
directly in front of him. Not a good situation. He was using a sliding
fuel guage with some type of cork float and the fuel would come out around
the guage wire.
I would suggest that if you pursue this type of system, the header tank
should seal tightly and have a separate vent line that would be up near
the height of the vent line for the center section tank.
My $ 0.02.

Terry, it was not my idea! I got a bunch of prints of different things
somewhere and this print was among them. I suspect that it was originally
part of the GN-1 plans. I'm not sure of that but someone drew up the idea.
Jack Trexor suggested that I take a picture of the print which I will try.
If it works out I will post it. Your suggestions sound great to me.

Subject: | Re: Venting fuel tanks |
Have the header tank vent in to the filler neck of your center section tank
.
Aeronca's have it that way.
If you use separate vents they must be at the same height and location.
I did have them at same height but had header tank vent at leading edge of
wing (high pressure)
and the center tank at 30% cord,.....low pressure area.
Gues what will happen at 65 Mph?
Your header tank will not fill !
Some things are learned the hard way
The Aeronca way is best way to do this system

FYI.T-crafts have wing tanks that drain into the 12 gallon nose tank, which
merely has a wire float. Allowing the wing tank to over fill the nose tank
will cause fuel to spew from the vent area in the nose, but there is really
no reason why an alert pilot would do that.not that I ever have. :-0
In the case of the T-craft, the main tank is the nose tank, and therefore
contains the fuel gauge. One could do the opposite.gauge the wing tank, but
then you really don't know what's in the main tank.
FAR's require that you have some sort of fuel gauge.but they don't require
that you use it. The Great Axel Purtee has a wire gauge on his wing tank
(that he can't really see), so the rumor is that he flies by time.what a
novel idea.but, then, he's a pro.

Subject: | Spruce vs. ????? |
Hello all!
Just recently joined this forum, and have a few questions. They are of the "newbie"
order, so take it easy on me. A friend of mine and I are beginning the
process of building a Piet. We have a few questions, as we plan our build.
1) Is there an effective alternative to Sitka Spruce? Here in Nebraska, Sitka
is a bit difficult to come by.
2) As I am a cabinet maker utilizing a CNC Machine, does anyone cut wing ribs
out of plywood? Drawing and cutting could be a fun project for myself.
Thanks for your attention, I'm sure we'll all be good friends by the end of our
build.

@Gary - I have a small mirror (shaped amazingly like Hello Kitty) on a lanyard
in the cockpit so I can check the gage in flight. I have done so, but not very
often. Typically, I use the mirror to make sure I actually reinstalled the
gas cap or to check the fuel level when doing lots of little short hops, like
giving rides.

@Gary again - off topic a little: my day job machine gives me continuously updated
fuel burn, amount on board and endurance. We were out last week trying to
get some stuff done and I pressed the fuel a little more then I normally would.
I landed with the regulatory minimum, but just barely, and I (should have)
had adequate fuel in both tanks according to the machine. Right as I was touching
down the fuel PSI warning light for the aft tank went on. Oops!
The moral? Even those fancy gages that you can read from the cockpit lie:).

Generally Douglas fir can be used for Spruce. It won't be as light but is a little
stronger. Often Douglas fir can be found locally but be sure you know what
to look for as far as quality. Study the material on rings per inch and runout,
grain etc. I found some for my project that was really good but I had to search
through 3 piles of 2X4s to find it.

Subject: | Upper Engine Mounts |
For those Engineers and flying Piet owners I would appreciate some advice.
I made my upper engine mounts per plans with the exception they are .090
4130. The plans call for 14 gauge steel (.080 I believe). I read an
article last night by Mr. Pietenpol where he stated one change he would
suggest for those installing C-65's (mine is a C-85) would be to lengthen
the mounts 3 inches. I've attached a drawing showing the change. I'm
planning to make the modification unless those in the know think I'm nuts.
Thanks,
Jack

Hi Mike,
Welcome to the forum.
When it comes to choosing wood for their Piets, a lot of builders seem to spend
an inordinate amount of time trying to save a few bucks. If Sitka is ordered
pre-cut from Aircraft Spruce, that wood will likely only account for 10% (or less)
of the total materials cost for the finished project. If you manage to find
a local source of a suitable alternate wood, and select and grade it, and rip
it yourself, you could reduce that percentage to 3 or 4%... for a total savings
of $600 or $700 (or, in other terms, maybe 10 tanks of AV Gas). Not that
$600 is an amount to sneeze at - it's just that the cost of Sitka (or Douglas
Fir, or Poplar, or Hemlock or whatever) is not one of the most expensive components
of the plane. Actually, shipping of all of your supplies will likely account
for more than the cost of the wood - maybe THAT is where to look for savings.
If aircraft builders only built with locally available wood species, only those
on the extreme west coast would build with Sitka. Wood can be shipped almost
anywhere.
Now, having said all that, I purchased my wood (Sitka) locally, from a specialty
wood supplier, in rough plank form, and ripped all of my wood on my table saw.
But then, I enjoy woodworking, so I didn't mind the extra work required to
do all that sawing.
As for your question about the ribs, it probably has been done at some point over
the past 80 years that people have been building Pietenpols, but it won't be
cheaper, and it won't be stronger, and it won't likely be lighter than the plans-built
truss ribs.

Hey Jack,
I believe that Mr Pietenpol already extended those upper mounts. The original mounts
for the Ford Model A are shorter than the drawings you attached (from the
supplemental plans). And if you look at the plan sheet for the Continental mount,
you'll see basically the same detail, but with a note that says .090 (sound
familiar?).
I'd say you're okay to use the plans without modification.
By the way, nobody THINKS you're nuts ... :)

Chuck,
First I'm not an Engineer, A&P, IA or an authority on wood stress
properties. I built a laminated spar because those that did know about
these properties told me it was stronger than a solid spar. Again, not an
authority, I was concerned about hidden flaws in the wood and the laminated
spar helped with that concern.

Is somebody/someone (how you say that? one/body.. I always forgot it) realy interested
in this "other" solution?. I was looking just for the Piet plans and
in particular the point the engine supports are fixed. In this 4 point there is
a lot of forces playing when the airlen take down, and there are simple bolts
joins; the iron pieces could be bigger or smaller.. I do not know, but there
are lot's of holes where the longerons end.. and it work fine!!!!!
I think the moment that this point play there major work is when the airplane touch
down... the engine want to go dow still, so there is a great traction force
applied to the upper joins.. I am ok?... now thinking in the longeron suggestes
door, i think the forces are slower than that's of the engine mount point.
Am I wrong?.. I am just playing with dynamic and statcis forces...
Let's burn some more neurons... ;0)

Subject: | RE: Venting fuel tanks |
Don,
I made my system in a similar way to Hans. I originally vented the header
tank with the vent at center section tank height with the vent pointing
forward. That created too much pressure in the header tank and would not
fill from the center section. Next I pointed in the opposite direction and
that syphoned the fuel out over the wing. I ended up putting the vent inside
the center section tank as Hans did. That work a treat. I only had a fuel
contents gauge on the center section tank. When that ran out it was time to
land!
