Hi Max,
Last year I purchased a Pazmany PL4 that was built in 1977 and never flown.
It has the Hurst-Airheart brakes on it. The parts are a bit pricey. Be
sure to order the correct material. They sell 2 kinds of seals, one for mineral
oil and one for auto brake fluid.
After a lot of searching I found the supplier in Minnesota.
The company is: Tol-O-Matic, Inc.

Thanks for remembering that Scott. Many people use stairway railing (usually
douglas fir) for the leading edges as recommended on this list by Mike Cuy,
and clear pine or douglas fir for the trailing edge. Save you some dough.

Doh-! Sorry for that last post. I intended to send myself the address so I
would remember to send a check for the youngsters who are restoring the
Piet, and I guess I sent it to the list instead.
Maybe for something Piet related in this post I can just say that every
landing I've made in 41CC so far has resulted in a slight little bounce
(love those 6.00x6's) and chirp. I have yet to actually grease one on but I
know my time is coming. I also have yet to operate it off the grass, but
plan to do so as soon as we dry up from all the rain we've had (wettest
March on record here). Darn... I guess I'll just have to get out there and
try harder ;o)

Oscar, do you chop the throttle when you're just a little above ground?
I maintain about 1200 to 1500 rpm at touchdown, then close the throttle once
the wheels are rolling.
this is on tarmac. My engine is an A-65.
Occasionally I hear the wheels rolling before I know I've landed.

Hello Piet flyers in North Texas, and Arkansas (or anywhere)
The planning for the 2007 Ada Air Expo is coming along nicely. We are
looking forward to another great day with a variety of warbird aircraft,
aerobatic performers, static displays, radio controlled model aircraft,
AND a sanctioned BBQ cookoff event.
I do hope so that some Pietenpols can make the trip. I'm the airshow
annoucer, and I would enjoy the chance of talking about your airplane
with a captive audience.

Humidity can change the dimensions of the paper. The changes to the scaling of
the document when it's printed can also have an affect on the accuracy of the
dimensions. When I plotted out the points on the jig I built and then compared
to the full-scale rib plan there was a difference of about 3/4" in the length.
I used MDF for the jig and haven't seen a noticable change due to humidity.

Yes... typically, I back the throttle to idle when I'm in the flare. I do
hold power down final, especially with a crosswind, but try to go to idle
before the mains touch. I'll try reducing power rather than chopping it. I
know it sounds like I abruptly chop power and that's what's causing me to
bounce, but it isn't that drastic. The airplane is already settling to the
runway when I come off the throttle.
Another thing to experiment with! First it was the "push the nose over and
Stuka dive to final", now it's holding power through the flare and
touchdown. I'm sure I'll develop my own technique in time. For now, the
biggest change from spam can days has been the "carrier landing" type of
approach, like you do in Pitts and other fast planes. Once the power comes
off on downwind, it's coming down and you sure don't fly a "square corners"
approach. I like it.

Hi Glenn,
I built my ribs in the house and in the span of a month. My template was
glued down and wood stops screwed thru it. My ribs are all the same size. I
guess the only question I have is if the template was correct to begin with.
Does "close enough" work in the case?
Thanks,
Dave

Dave,
This subject keeps resurfacing. Do a search of the archives and you'll
find several discussions about it.
In any case, the short answer is that the full size rib plan is a large
photocopy, which may or may not be accurate to the plans. The copies are
affected by humidity and paper shrinkage. The copy may have been
accurate at the time (and location) it was printed, but in your shop,
the size may be slightly smaller (or bigger). Just 1% shrinkage can
result in a chord reduction of more than 1/2". Overall, the shrinkage
shouldn't be a problem - the only real concern is the spar spacing,
which should be 28 3/4" center-to-center. The main goal is a full set of
ribs with a consistant profile. If your ribs are 1% bigger or smaller,
it will not be a concern as long as they are all the same. Lots of
builders report that they have built their ribs directly from the full
size rib plan.
The full size rib plan is handy for a few things:
1.) Shows where BHP introduced the vertical uprights adjacent to the
spars (not shown in the 1934 plans)
2.) Can be scaled to locate the diagonals, since no dimensions are
given in the plans
3.) Can also be scaled to determine sizes of 1/16" ply gussets.

Hey Bill. Please tell me that the proper measurement is 28 3/4 from the
back of the front spar to the front of the back spar and not centre to
centre - otherwise I have 16 beautiful albeit incorrect ribs in my shop!!!

Hey Scott,
I was just shutting the computer down to go home, and your e-mail popped
up.
I'm going by the plans, which show 1" spars, and the spacing is 27 3/4"
from back side of front spar to front side of back spar (see attached
JPG clip).
That would translate into 28 3/4" center to center.
Maybe you need to re-measure.
Didn't you use one of the late Charlie Rubeck's ribs to build your jig?
I can't imagine his ribs were all incorrect.
Bill

Hey Oscar,
I'll let you in on a little secret.
My friend and mentor, former Corvair and TBM carrier pilot, Bill Rewey,
who's logged over 500 hrs. in his Piet including four 1200 mi. trips to SNF,
still bounces his landings. Not big bounces but still bouncy.
So any day you make a "smooth" no-bounce landing, reach back and pat
yourself on the back, and say "well done you old F--t". By the way, I don't
know how much it would influence the landing, but Bill told me to keep only
15 lbs. pressure in my 6 x 6.00 tires. Sorta like a "dead" tennis ball or
basket ball I suppose.

I've been having copies made by a Graphics business who have dealt with
Archirects for at least the last 50 yrs.
These copies are the Riblett 612 airfoil which are being requested by a
number of Pietenpol builders.
I had to reject the first dozen copies because they were a full inch shorter
than the original pencil drawing.
Since then each time I order copies, I insist that the overall length of the
rib is 60 inches plus or minus 1/16".

I consider myself to be basically cheap, and as much as I like to spend
money, I have to make sure I'm getting maximum value for my money. I
feel I get this with my EAA membership. Besides supporting a big
organization that is very influential in keeping people like us in the
air, there are other immediate tangible benefits. As Oshkosh
attendees, the substantial discount you receive on admission just about
makes up for about half our membership cost. You also get which ever
magazine you choose, be it Sport Pilot or Sport Aviation, etc, and we
all know a magazine subscription is worth about $25 bucks itself. So
on a dollar for dollar basis you come out good, AND you support
aviation in all it's different colors, that plus all the good stuff
lurking in the members section of the EAA web site. To me, it's money
well spent.
The Piet in Roundup Montana intrigues me. My wife is from Roundup,
Montana, and her step-father was longtime FBO of the Roundup Airport.
I don't know what he may know about the Piet, but he's long since
retired, and for whatever reason dosen't much like to talk about his
flying days (although, when you get him in the right mood he does have
great tales to tell). He also did lots of missionary flying in 3rd
world countries. There was a writeup on the Roundup Piet in the BPA
newsletter at the beginning of the year. I'd like to track them down
and see if I could get a copy of an historic photo or two to add to my
office wall. Next time we visit Roundup (probably this summer) you can
bet I'll be checking things out! And I'll be sending off a check to
donate to the restoration effort.
As far as building our plane I'm accumulating knowledge, plans, and
tools. Won't be long and I'll be creating a rib jig. It will be NX3746
(already reserved a number). If we ever get rid of this cold and rain
up here, I can get to work in the garage shop!

First of the checks came in today, thanks guys. I don't want to make
too much out of this, but I would like to send off whatever we can
gather by next Wed the 11th as I am leaving the 12th to set up for Sun n
Fun.

I asked a fellow, Damian, who's a flight instructor the next airport over.
He's an instructor who has a school that teaches Alaskan Bush pilot
techniques. Very good instructor who talks down to earth. His claim to fame
was to teach Harrison Ford tailwheel for that old movie.
Anyway.....his advice to me was to , if comming down at idle, to use a
little power to lengthen the flare. This way you decide when you'll touch
down.
Also on a light plane like a Piet,,,be ready on the flare, if a crosswind
catches you, to give a burp of power. The blast across the tail improves the
rudder control ten fold.
Works like a charm.

Roman,
I plotted the Riblett 612 airfoil from the co-ordinates you sent me
(thank you very much for that)on mylar and had the printers copy onto
mylar. They all came out within 1/16" of the 60" chord.
Mylar is the plastic drafting we used to use in the days when
drawings were hand drafted.
It is stable and doesn't stretch or shrink significantly with
temperature variations and humidity. Also it is more durable than
paper.
I was going to experiment with it to see if epoxy sticks to it or
not. If not then will build the ribs directly on top of the pattern.
There are at least three of us here in Western Australia who are
going to use the 612 airfoil.
Apologies to the purists, but we like the idea of improved
performance promised by the 612.

I flew my plane (GN-1) into Ada last weekend, I met some friends there who
also flew in for BBQ down the street at Bob's BBQ. Ada's terminal is a nice
facility, well kept, with an internet enabled computer for weather & other
information. They also have a nice comfortable crew lounge, and a nice,
clean/well kept crew car (a Chevy Suburban, great for getting a group of
pilots to & from Bobs or anywhere else in town. The guys at the desk were
very helpful and friendly, they gave us all bottled water when we were
departing. I'll be back again.
I was planning on making the airshow, but a friend's wedding happens to fall
on the same day. He is a pilot, he'd understand if I missed the wedding.
Terry, I'm sure we'll be back out there before too long, I'd love to see
your project sometime!

Hello Piet flyers in North Texas, and Arkansas (or anywhere)
The planning for the 2007 Ada Air Expo is coming along nicely. We are
looking forward to another great day with a variety of warbird aircraft,
aerobatic performers, static displays, radio controlled model aircraft, AND
a sanctioned BBQ cookoff event.
I do hope so that some Pietenpols can make the trip. I'm the airshow
annoucer, and I would enjoy the chance of talking about your airplane with a
captive audience.

Just came back from the shop. Both Charlie's rib and the 16 I copied from
it are 27 3/4 inches from the back of the front spar to the front of the
back spar. I guess we're talking the same language. The heartrate is
starting to slow down now...
