Subject: | Re: Wavy Okoume Plywood Leading Edge |
This morning while fueling my Pietenpol as I looked down both wings the plywood
is pulled down between each rib by the fabric. I used Okoume plywood too, but
I don't remember it being warped prior to covering. It still flies very nicely.
Just my $.02

WF2,
In your wing pic, there are two aets of green structural items; one of which is
clearly part of the wing itself. The other appears to be some form of wing stand...
Would you care to show a few pics of the stand, and tell us how is works, etc.?
Thanks!

This guy has great ambitions. I picked up the phone yesterday and called EAA to
see if they knew about this fella. I'm thinking that it would be a kind jester
to bring him to Osh next year so he can see how it should be done. Long story
short, It was lunch time in Osh so I didn't get a chance to speak with anyone.
If you look closely you can see all the nails or screws he use to attach the covering
material to the longerons. I think at best this gentleman has something
he might be able to taxi around a little. There is not enough power there to
even get the tail off the ground. Nothing is straight and all the cables are
just kinda tied on with knots.
I may try and call EAA again today if I get a chance. I think the best help we
can offer him is to mentor him for his next project.
He has registration numbers on it so I'm sure EAA could find him that way. I don't
think that CNN would give up the guys contact information to any of us common
folk. Maybe to EAA, but not us.

Just a thought and not advice. At least when I do something the second time

Subject: | Introducing myself and question about lumber purchase... |
Hello. My name is Bill Kendrick from San Antonio, TX. I am new to the list and
just wanted to introduce myself. I made the decision a few weeks ago to start
a Pietenpol build. I have only constructed my work benches and purchased the
set of plans. I plan to start with the fuselage but have not purchased any
materials yet. Can any of you offer suggestions as to what to purchase first
regarding lumber? I have priced the A.S. fuselage kit ($1085 I believe) but
was wondering if the bargain bag would be a better way to go given the much 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?
Thanks,
Bill

This is how the prop broke. Wow, first weak link is gone.
EAA national knows of the guy and they say that they are in no position to help.
Although, If we got this guy to the OSH fly-in they might be able to provide
tickets for him to attend. Pretty weak response from them as far as I am concerned.

I've not heard anyone complain about the bargain bag.
But, not enough to build a fuse I don't think.
So, where are ya and what are your capabilities and goals?
If you are a well connected or equipped woodworker, I'd try to buy rough lumber
locally and mill yourself. If you aren't, or want to build quicker, just get
the kit. So it really depends as you see.
Doug fir is pretty easy to get if you don't mind the weight penalty, which may
be moot if you're not going to install batteries, transponders, radios...
If you're using a hunnert horse corvair, may not matter. If you're using a ford,
it might.
If you live near Madison wi, spruce is available locally. Maybe also so out west
or merely a very well stocked lumber yard. If you live near Atlanta, shipping
that stuff won't matter because you can pick up locally. Same for other vendors.
Great choice of plane. Also consider getting an abandoned project as a kick start,
unless one of your goals is doing it all yourself.
Cheers,

Tim, I used 1/16th inch thick plywood from Aircraft Spruce (not the type
you mentioned). I put on two coats of varnish after completion of the
structure and have never had any problems with it. Just finished the
covering and painting and it looks pretty good. I would suggest you remove
the bent plywood and start over. As soon as possible after completing the
structure give it a couple of coats of varnish and everything will be OK.

All we would like to do is communicate with this fellow. Help him in his project
and encourage him in his efforts. Would the operator (Matt) of this forum have
any way to know if he has looked at this forum or tried to join?
His coming to OSH would be a triumph in publicity for EAA, but that is not what
this fellow needs. Coming from such a poor country, he would be overwhelmed at
OSH and probably deeply depressed and ashamed of his efforts. If he just had
the plans for a Piet, or GN-1, or maybe even a MiniMax would be a great help.
Ship him some Spruce, chromoly, some fabric, some T-88. Maybe even an Aerovee
engine, a close to-run-out A-65, an old prop...maybe even some encouragement!
How about Michael P's set of building videos? Maybe an old Nicopress tool,
cable, screen door turnbuckles! Anything would be better than cables tied
in knots!
Let's try to help, not use him or try to show him what great things we can do in
this country...with virtually unlimited resources!
Enough of my preaching,
Ray Krause

Hi Bill,
You can NOT build a fuselage from bargain bags of spruce from Aircraft Spruce.
The wood in the bargain bags is all good quality Sitka, but every piece is a
random size, obtained from offcuts. The longest pieces in the bargain bag are
5 feet in length, with thicknesses varying from 1/4" to 1". The longerons of
the fuselage are 1" x 1" x about 16 feet long.
Having said that, one or two "bargain bags" would be a wise purchase if you're
building a Piet, (assuming you have a table saw, or some means to re-saw to the
sizes you need).
Bill C.
