This is awesome. I know that it was posted recently, but I never did come back
to watch the whole thing and lost track of it. Very simple test to prove how
important it is to eliminate drag. It is making me reconsider the shapes of
a few items I've already fabricated. I hope I don't get stuck in the never ending
"Jim Markle" cycle of improving everything to infinity. Just kidding Jim!

My setup is about the same, bushing/tube through torque tube, welded in place.
Bushing/tube (heavy wall) bored out just enough for a 1/4" bolt to slip through.
Stick forks fit over each end of tube with thin washers between to provide
flat bearing surface/spacer for stick forks. I am also using push/pull tubes back
to the bell crank and it appears, (no wings or ailerons connected yet) that
I have zero play as well but very free/smooth. See how that all feels in flight...someday.

Just one thing on the drag issue.A round shape perpendicular the the airflow is
obviously very restrictive,but a round cylinder at an angle is an ellipse,the
steeper the angle the more oblong the ellipse and the drag on an ellipse is much
closer to a streamlined shape than a round shape,so if your round shape is
at more the 20 degrees the drag factor is negligible,especially in a Piet with
a top speed of 100mph and cruising far below that.Dave

For those of you who have put a neat looking logo such as: "Corvair", or
"110 HP" on the side of your lifter covers; how did you do it? I have
considered just painting it on or cutting the design out of stainless
sheet which generates the additional question of; "How is it attached?" I
know the Ford guys sometimes do the logo thing on the front of the case
too so this might not be a purely Corvair question.

Dave:
In other words, the cables traveling fore and aft to the controls will
have reduced (negligible?) drag but the ones perpendicular to the flow
will generate considerably more drag. I assume that the cris-crossed
wires between the flying struts are not sheltered from the drag inducing
airflow since the forward strut (being a streamlined shape) will have
re-merged the airflow prior to it's encountering the flying wires. This
also probably means that the airflow striking the rear flying struts will
be "dirty" since the flying wires will have mucked up the airflow in front
of them. Therefore, the best way to reduce drag would be to add tiny
streamlined shapes to those nasty flying wires. Who says this aeronautical
engineering stuff is hard?

Tom, If you can get a hold of William Wynne he gave us ours at Brodhead the
1st time we made it there with the airplane (he might have them for sale o
n his web-site).- They are a metalic silver "foil" like self adhearing de
cal.- I got lucky when I got bored and stipped and painted dad's covers f
lat silver, and orange, I did not know that the decals were silver, matched
perfect.- Any decal, sign shop should be able to make them, for a few bu
cks.

I am in the process of streamlining my flying wires. I got some plastic corners
from home depot and cut them down to 3/8 inch wide with heavy duty scissors. I
then put gorilla duct tapearound the front edge and then folded it over to hold
onto the plastic. I hope this will give me a streamlign effect. I also got some
aluminium house siding and folded it over to clamp onto the verticle landing
gear. Hopes this works. Gardiner

I have a great deal of respect for anyone on the list who has gone to the t

owever=2C I wanted to let others on the list know how few tools are require
d to actually make progress on this great old bird. Sometimes the money sp
ent buying a brake=2C bandsaw=2C tig welder=2C plasma cutter etc just slow
s down the process of building unless your finances for your piet project a
re limitless. What drew me to this project in the first place was the simp
licity of the machine and the limited tools required to build her. The att
ached photo represents 8 hours of shop time in my little one car garage wit
h a vice=2C hammer=2C drill press=2C jigsaw=2C grinder=2C files=2C sandpape
r and scotchbright. I purchased a piece of 18" by 18" 090 4130 from a loca
l metal supplier who sheared it for me into 1" and 3/4" strips (yes...with
the grain!). Total cost: 40 bucks. Now off to my Tig welding buddy down t
he street to have these welded up (that will cost a bottle of Canadian Wisk
ey). By the way=2C there is still enough left over from that piece of 4130
to build the remainder of the wing fittings.

Tom - Contact me off-line. My wife cut my "AirCamper" stencils on a machine she
has and we painted the valve covers with high temp paint. Came out great.
She'll cut stencils for you, too, I bet. She loves that stuff. She'll even give
you instructions. She sent a set to Gardiner Mason as well.

In other words, the cables traveling fore and aft to the controls will have
reduced (negligible?) drag but the ones perpendicular to the flow will
generate considerably more drag. I assume that the cris-crossed wires
between the flying struts are not sheltered from the drag inducing airflow
since the forward strut (being a streamlined shape) will have re-merged the
airflow prior to it's encountering the flying wires. This also probably
means that the airflow striking the rear flying struts will be "dirty" since
the flying wires will have mucked up the airflow in front of them.
Therefore, the best way to reduce drag would be to add tiny streamlined
shapes to those nasty flying wires. Who says this aeronautical engineering

Just one thing on the drag issue.A round shape perpendicular the the airflow
is obviously very restrictive,but a round cylinder at an angle is an
ellipse,the steeper the angle the more oblong the ellipse and the drag on an
ellipse is much closer to a streamlined shape than a round shape,so if your
round shape is at more the 20 degrees the drag factor is
negligible,especially in a Piet with a top speed of 100mph and cruising far
below that.Dave

At the speeds the Piet travels, the air has time to get around the round wires,
play a game of gin rummy, and take a nap before it gets to the next object in
it's path. :P
Seriously, the stranded cable used is NOT the same as a solid round object. The
surface texture makes a difference, it makes the airflow turbulent, and follows
the shape BETTER, kind of like the dimples on a golf ball.

Subject: | Free cardboard template material |
I recently needed some posterboard for some sheet metal templates, and a do
llar a piece seems to be the going rate for a 24" by 30" or so.- Go down
to your local feed store (I remembered my highschool days of stacking horse
feed by the ton), hardware, or even grocery store and ask if you can have
the cardbord the put on the pallets the stack bags on.- Water softener sa
lt, dog food and other paletized goods almost always have a piece of cardbo
rd on the pallet so bags don't rip open.- The pieces are usually at least
48" by 48", and just the right thickness for cowling, fuselage coaming etc
mock-ups. Grab them while you can they will come in handy, I was also able
to make cardboard streamlined tube mock up by wraping and gluing it around
the tubing and sliding off when dry.- Much cheaper to mess up on the car
dboard than $15 per foot tubing!

Gary,
So you are using pushrods instead of cables??? If so, what controls are you doing
that with? I was considering a pushrod for the elevator control and sticking
with cables for the rudder and ailerons. Would you do it again if you could
go back?
Thanks,

The push rods are only for elevators, and it was incredibly easy! I really
wanted a laminated control stick and couldn't figure out a way to use the
cables...that's the reason for the push rod. I'd do it again in a
heartbeat...well, actually, might take a few years, after building ribs
first, as I promised Axel!

Gary,
So you are using pushrods instead of cables??? If so, what controls are you
doing that with? I was considering a pushrod for the elevator control and
sticking with cables for the rudder and ailerons. Would you do it again if
you could go back?
Thanks,
Mike

Thanks, Barry. That was from a year or so ago. I'll have to get some new
pics to Chris Tracy for the www.westcoastpiet.com website.

I'm with you, Scott! I shaped my cabanes and gear struts with an 80 year old
spoke shave that I inherited from my grand dad. But I have to confess, I am
considering one of those new fangled electric planes for the wing struts.
(once I get those ribs built, Axel).
Hope you make it to Brodhead this year..and don't forget that bottle of
Canadian Whiskey!

I have a great deal of respect for anyone on the list who has gone to the
time, expense and effort of putting together a well equipped workshop,
however, I wanted to let others on the list know how few tools are required
to actually make progress on this great old bird. Sometimes the money spent
buying a brake, bandsaw, tig welder, plasma cutter etc just slows down the
process of building unless your finances for your piet project are
limitless. What drew me to this project in the first place was the
simplicity of the machine and the limited tools required to build her. The
attached photo represents 8 hours of shop time in my little one car garage
with a vice, hammer, drill press, jigsaw, grinder, files, sandpaper and
scotchbright. I purchased a piece of 18" by 18" 090 4130 from a local metal
supplier who sheared it for me into 1" and 3/4" strips (yes...with the
grain!). Total cost: 40 bucks. Now off to my Tig welding buddy down the
street to have these welded up (that will cost a bottle of Canadian Wiskey).
By the way, there is still enough left over from that piece of 4130 to build
the remainder of the wing fittings.

Thanks for the input Domit. I had not thought about the wires being dimpled a
low speeds. Are you related to Kevin&Quot?

At the speeds the Piet travels, the air has time to get around the round wires,
play a game of gin rummy, and take a nap before it gets to the next object in
it's path. :P
Seriously, the stranded cable used is NOT the same as a solid round object. The
surface texture makes a difference, it makes the airflow turbulent, and follows
the shape BETTER, kind of like the dimples on a golf ball.

I thought the whole idea of this hair-in-the-air, goggly-eyed,
silk scarf stuff was to hear the wires sing, sorta like Julie
Andrews without the Alps.

Therefore, the best way to reduce drag would be to add tiny
streamlined shapes to those nasty flying wires. Who says this
