| Subject: | Re: Wavy Okoume Plywood Leading Edge |
I am only studying to build a piet for now. Seeing this phenomena is interesting.
A thought to remove the moisture could be to bag the wing and pull a low vacum
on it removing any moisture from it.
Some painters plastic, some duct tape to seal the bag.
A simple vacuum Venturi and compressor to pull it down. It may remove the moisture.
I do think though if this occurred with a heavy UV load and the glue within the
wood softened and re hardened, then there are other concerns.
Interesting subject.
I hope the repair however it is accomplished is simple for you.

Welcome to the club Bill. As others have mentioned the bargain bag won't work.
I started with the ribs which allowed me to gain experience, find out if building
from plans was a good idea and the cost for rib parts was pretty minimal.
I used Douglas fir for my fuselage longerons and wish I used spruce. Starting
with the fuselage will raise many questions early on, like which engine, gear,
long or short fuselage, etc. However you begin, as time goes on you may
find deals on partially completed projects, wood from projects never started,
etc. good luck and enjoy!

lower price. I guess my question is will there be enough footage in the bargain
bag (or multiple bargain bags) to do the fuselage or at least get started?

Bill, I forgot about Alamo hardwood here in San Antonio. You will have to
learn how to select the wood. Grain, ring count and so on.
The cost of the wood will be only a part of the cost. Remember, I am doing
a restoration so I did not need big wood. The bargan bag gives you good
cheap wood to practice and screw up. You may have to wait some for your
bag. They wait until they have enough scraps to fill a box.
To start you might do the tail or ribs. For me, seeing a part that looks
like a plane part is good motivation. But it is your build.
Blue Skies,

Bill;
Too bad you didn't make your decision to start building a Piet a few years ago
when I lived in San Antonio. I had my Piet out at San Geronimo (8T8) and had
(still have) all of the plywood and rough lumber (Douglas fir) to build a another
Piet fuselage, wings, and tail surfaces. Would have been easier for me to
pass it on to a new builder than load and haul it 2300 miles to sit in my hangar
here in Oregon ;o)
However, several others have mentioned that it is possible to find already-started projects in a good state of progress at a very reasonable price. In fact, the one that Tom Brant was offering for $1500 would be worth looking into and would save you a lot of time and money. He is in the Minneapolis area but you could drive up there over the holidays with a trailer and have it back in time to start on it as a New Year's resolution. There are only three pictures of Tom's project on Westcoastpiet but from what I see in the pictures, it's excellent material and workmanship. Check it out: http://westcoastpiet.com/images/Tom%20Brant/Tom%20Brant.htm . By the way, you will want to bookmark the Westcoastpiet site because if you ever have a question about how something is built or what it looks like, you will absolutely, positively be able to find a picture of it by browsing the pictures there. It is the Air Camper's "Treasure of the Sierra Madre" ;o)

Steve: there are only two types of people in aviation: high-wingers and low-wingers.
In south Texas, high-wingers have shade wherever they go ;o)

Oscar/Steve,
Thanks for the info. I really considered the Flybaby because of the leg room but,
although I seldom have a passenger, I like having the extra seat just in case.
And yes, the shade will be handy;)
Thanks,
Bill

Yes, really. All airfoils rely on laminar flow. That is different than a laminar
flow airfoil, which is specifically designed to exploit laminar flow.
The opposite of laminar flow is turbulent flow, as seen during boundary layer separation,
which nearly defines a stall.
Do the original plans call for gluing or nailing the leading edge skins? Nailing
would allow the skin to move with moisture content variation.

Okay, maybe I misread the original statement.
Having a smooth transition between the leading edge and the plywood attached to
it is important, since this is the only part of the wing that will experience
laminar flow (probably not more than the first 6" or so of the Pietenpol airfoil
will experience laminar flow), and roughness or sharp edges would disrupt
that.
However, after the covering is applied, the fabric will pull down on the plywood
between the ribs, effectively changing the airfoil. But it's been that way
for over 80 years, and seems to be working all right so far.
