As usual I am responding to a thread that died out a couple of weeks ago
concerning putting in a step for the pilot. Early on while I was buying
metal parts from Ken Perkins in Olathe, KS he made an offhand comment that
caught my ear. He said that if he had it to do over again he would put in
a sliding pipe setup that could be slid in and out as needed. I took his
idea and came up with this setup. Basically it consists of two pieces of
tubing with one that slides snugly within the second. The outer tube is
about 8 inches long and the inner about 14 inches. These were scraps at
the time and I don't recall the wall thickness but they were not particular
ly heavy.
The outer tube has a "V" notch cut in one end that the retaining bolt
slides into when the step is extended. The inner tube has a washer welded
on one end and a retaining bolt near the other end. The outer tube is
secured with two metal straps that are tack welded only. Believe me this
tack weld is more than sufficient to warp the outer tube which caused me
some grief BUT when the straps were bolted down they pulled the warp right
out and the two tubes slid snuggly but freely again. I mounted the
assembly on a piece of 1 inch ash directly over the 1/4 inch floor ply in
the corner where the seat former and diagonal brace meet. This gives lots
of gluing surface plus the four bolts which pass completely through the
floor with washers and nuts underneath. I have stood on this (all 220 lbs
of me) and bounced with no ill effects. I will not make any final
judgement on proper placement of the step until I get the wing center
section up on the cabanes which, praise the Lord, is not too far down the
road.
By the way, all the blind nuts on the seat stringers are from a discarded
trim system. I do learn - - - eventually.

Oscar,
Your are welcome to my house and airport on the way up also. KWJF Fox Field in
Lancaster, CA. Heck, I might even be able to make part of the trip with you.
Two ship sounds fun. Just let me know what you want to do and I'll do what
I can to make it work.

Hi Oscar,
Not to clutter up your route any more than necessary! but I am in Santa Rosa, CA
just 50 miles North of San Francisco. Sonoma County is home to EAA Chapter 124;
and my Piet is not quite as far along as Gary and Mike and Vic's but if you
should be blown off course by the great valleys prevailing winds you are welcome
to stop here as well. We have a great mexican restaurant, family run as well;
La Bufa.
Anyway let me know as well where you will be landing as I can make it to most places
here in Northern CA in a reasonable time.
Cheers and have a good flight whenever you manage to bring Scout North.
Cheers,
Jim B.

Jake, No!, yours is not the smallest. I saw a picture on the British Piet
site where a fellow built a Piet in a one-car garage. I'm using a two-car
garage and that's pretty tight -- don't know how he did it. C

Hi Tom,
Your step is looking good; but... I was going to put my step in almost the same
spot. It is too far forward; you will hit your head constantly on the wing center
section, or the corner of the wing even if you have a cut out.
I moved my to about four inches behind the rear seat back; and if I forget I still
bump my head once in awhile.
Cheers,
Jim B.
PS I like the way you did your step though; my is permanently out.

Finally was able to do a few tests with the engine mounted to the airframe and
the 76 x 42 prop..........pretty much ran like a dream! was able to get to 1950
rpm. if i crossed 2000 rpm the engine would start to cough a little bit. The
starter worked real well too.

Chris,
That looks and sounds GREAT. What a great day for you.What thrust numbers did
you see? I believe you will start a new movement with that arrangement. Can
you say Mitsubishi Collage?

Chris:
You should be congratulated by a great number of Pietenpol Wan-bes.
I will be one of them.
The top end is an easy cure to get power at full throttle, without burning valves.
due to a lean mixture. With the prop shaft extension, a smooth look and an
excellent air flow will be a result.
What cooling radiator do you use, and where is it placed ? If you keep a good air
space between the top of the radiator and the bottom of the wing, it will give
you added lift where the air velocity is the greatest.
I have a good 10 inches with a cross-flow radiator, flying feel is very different
with the added lift, if interested in my installation give me a shout on my
Email,
Pieti Lowell

thanks!
After looking over your plane at brodhead, i mounted my radiator the same way.
i had a custom aluminum crossflow radiator built for 250 bucks. weighs only 8lbs.

I have a question on CG limits. I have just completed the weight and
balance calculations on my Pietenpol (Model A engine, one piece wing,
see attached). My CG is within the limit of no more than 20 inches
behind the wing leading edge - just barely. Is there any value to
moving the wing back another inch so it has some margin ahead of the 20
inch limit?
Here's the numbers I calculated:
Empty weight with oil and water - 710 lbs
CG with 200 lb pilot and 10 gallons of fuel - 19.9 in behind LE
CG with 170 lb passenger - 20.1 in behind LE
The cabanes are already 2.5 inches back from vertical. Theoretically, I
am OK with the wing as it is, but would it be better to have it more
toward the center of the allowable CG range?
Appreciate any thoughts.

I fabricated the elevator and rudder control horns over the past couple of days
to the plans. Fun work and a good test of my newly acquired gas welding skills.
I have a question for those of you who built them to the plans. After zinc
chromating them it occurred to me that there will be a large area of unprotected
metal inside the horn since the forward end that attaches to the wooden
spar of the control surface is open ("butterflied" if you will to attach to the
spar). What can be done to protect this bare metal? I thought of spraying
linseed oil or fluid film into the opening and sloshing it around. I'm not keen
on seeing corrosion on these horns which are so visible on the completed aircraft
(not to mention they are a requirement for controlled flight!).
Regards to all Pietenpol builders and fliers out there.
