Hi Guys,
I am thinking of changing my wire spoked wheels for normal aircraft type
wheels. What tires sizes are you guys using? 15-6.00x6 or 8.00x6?
Cheers

I have a steerable non swivel homemade wheel on mine. It was fairly simple to
make. A swivel wheel would be nice but I seem to get along fine without it.
My home strip is 35-38 feet wide and it turns just sharp enough to turn around
on it. It would be nice to be able to just shove backwards on the plane and
have the wheel swivel around, but the tail is fairly light and the tubes on the
skid design make a good handle to just pick it up and walk with it. Once you
get used to just a steerable tailwheel you probably wouldn't even notice not
having one.

Subject: | Question for Grega buliders/owners |
The Grega landing gear has steel channels on the that run across the
bottom side of the fuselage from longeron to longeron. These channels
are welded to the wing strut fittings.
Does anyone know if bolts run vertically through this channel and up
through the wooden crossmembers on the top side of the fuselage
floor? That is, how are the steel channels held to the fuselage?
Thanks,
Jeff

I've never seen reference to this with regards to full scale aircraft building,
but an old tip for forming wood strips used by model boat and airplane builders
is to use ammonia water. Ammonia softens the lignin in the wood, the stuff
that binds the cellulose tubes/bits together, and allows the wood to be bent more
easily, and when it dries out the ammonia evaps leaving the wood in more stress
free condition, i.e. the bends more permanent, than water alone. Laminated
wing tips, hull planking that requires sharp bends, that sort of thing all
work well with this technique. But I am sure steam or hot water does a reasonable
job. I have done both and can attest to the ammonia technique - curved parts
for wing tips for example barely spring back after drying. I cannot attest
to it's use in homebuilding aircraft, but someday I will build a rib using this
technique and bend and twist it to see if it is sound.

Hi Peter, (A fellow Pieter), We started off with 600-6 tires on a set of Azuza
wheels, and wore the tires out and put 800-6 tires on the same wheels. It lands
a little better on the rough stuff, and just about the same on pavement.
I thought it looked like it had monster truck tires on it when we first put the
800's on but after looking at pictures with the 600's on it looks much better
with the 800's.

Depends on how much flying you are going to be doing in that rugged outback.
I went with 8.00x6 on Matco wheels since I want to be able to land in an
open field if I need to and it looks great (but haven't flown with them
yet).

Oscar & Mike,
This mirrors my experience with an A-75 and a Hegy 72 x 42 prop. Fresh A-75, rebuilt
Stromberg (yes, it's exactly the same as the A-65), new mags, etc, in other
words, a strong A-75. Other than what y'all mentioned below, the only other
internal difference is greater piston to cylinder clearance.
Pulled about 2150 static and about 2200 in a 50 mph climb on a cool day, maybe
50rpm less on a hot day. At WOT it would pull 2400 rpm in level flight at 600
ft about sea level in cool weather (2J0 is about 10' above sea level). A perfect
A-65 prop, but about 250-300 rpm low for an A-75.
This prompted me to buy a 73 x 39 from Clark at Performance Propellers. It
was a prop he had made for his Cub, for hot, high density altitude conditions
with a passenger. On a hot day it pulls 2500+ in a 50 mph climb, and 2600 in
cool weather. It's really too much of a climb prop for cool weather, but perfect
for hot weather, which is what we have most of the year. It's also a real
work of art. 54 laminations of hard maple, thinner than the Hegy in profile,
but thicker and larger thru the hub.
The difference was AMAZING. Climbs out like my neighbor's Cub with a C-85 (well,
almost), and seems to be much smoother and happier cruising at 2400-2450
and 62-65 mph at about half-throttle, whereas before it was 2150 (rated cruise
for an A-65) and maybe 2/3 throttle for 67-72 mph. I'm referring to actual throttle
movement here. I thought about installing a vacuum guage to see just how
much throttle I'm really giving it, but then came to my senses (Hey, it's a
Pietenpol! not a Cessna!).
I may trim the Hegy a bit (71 x 42, or 70 x 42...) and see if I can make it act
like something in between the two, maybe 2400 in climbout and 2600 at WOT, to
get back a little cruise speed. Then again, it's not about speed anyway, is
it? :-)

I've just been bitten by the Piet bug. I'm waiting a few years to start on
a Velocity and just got bored when viola! I actually saw the video on the
EAA website celebrating 70 years of Pietenpol's then started cruising the
web. It wasn't until later that I realized my as of yet unread EAA mag was
collecting dust with a great Piet article in it.
I have yet to buy plans or really scan this email list. Is there any place
a newbie can go for a general list of recommendations? Are the plan
additions worth it? I was thinking of the foot extension (I'm a little on
the heavy side and tall), I was also thinking of the full scale wing rib
drawing, putting in a front door to make it easier for the boss, 3 part
wing.
Any recommendations, directions and/or suggestions would be gratefully
appreciated.
I'm located in Santa Fe, NM. I've never actually seen, sat in or flown in a
Piet. I had started a Cozy MK IV (composite canard) and the emp section of
an RV9 in the past before deciding to head off in my current direction.
Thanks,

I too, have used the "ammonia technique" with boat models and RC airplanes. I've
always wondered whether or not this weakened the wood to such a degree that
would make it unsafe in a full-scale airplane or perhaps some other reason that
others don't typically use this practice. I've got to assume that since this
is a common technique in model building, and since most homebuilders have some
modeling background, the fact that it's use in homebuilts seems rare indicates
that there's something we don't know. BTW, rather than water mixed with
ammonia, I've always just used Windex. Spray it directly on the wood and it works
great. Does anyone have any reason this souldn't be used in homebuilding?

Subject: | Newbie with the usual annoying questions |
Ok fellas,
I'm brand new to this list, but am VERY impressed by the level of support and participation
on this particular forum. I've long considered building a Piet for
all the usual reasons (all-wood, wallet friendly, nostalgic, etc), but since
I live near Boulder, Colorado, where the average 85 degree summer day brings
the density altitude slightly north of 8000 feet, I've wondered about it's performance
on any day that isn't crystal clear and 50 degrees. I understand the
engine options are numerous, and I would like to get some real-world feedback
on the performance up in the thinner air for given engine/prop choices. I'm
specifically concerned with Rate of Climb and Takeoff Roll specs. I also notice
that there are at least a couple builders in Co. area, and am wondering if
your birds are flying, or still...ummm....in the nest. Thanks for all your help.
Jeff

Hey Bob
Welcome to the Pietenpol clan, I am in Castle Rock CO, and little South of
Denver. You can come by any time if you make it up North sometime. Thats
quite a leap from a Velocity to a Pietenpol (kind of like going out to buy a
new 2008 Corvette Z06 and coming home with a Model T) but it sure will be
cheaper and easier. I am building a long fuselage Piet with a
Corvair.andthree piece wing (which is how most people build their
wings). Flying out of
a higher altitude like me you probably will need more than a C-65 for an
engine (as most people use), but their are lots of options. The best place
for recommendations and ideas are the archives of this newsgroup. Here are
my standard newbe recommendations:
- Order the basic and three piece wing plans (maybe long fuse plans) from
Don Pietenpol (full size rib plans aren't needed IMO)
- Join up with the nearest EAA chapter (can find list of all of them at
www.eaa.org)
- Order all four Tony Bingelis books (off EAA site)
- Order the Mike Cuy Piet DVD and watch multiple times

Hey Jeff
I am down in Castle Rock CO and asked the same questions when starting my
Piet project. Density altitudes at my airport East of Colorado Springs on a
95 degree day will be around 10,000 ft. I learned to fly and instructed in
Cessna 150s at Jeffco airport near Boulder on 95 degree days with over 200
lb students and the 100 HP O-200s in those got us up high enough at least to
do stall practice. Thats a 1000 lb empty (but cleaner) aircraft so I figured
a 100 HP in a 700 lb or so Pietenpol should be enough. Can't say for sure
till it flys however.
If you want to come down and see my project (long fuselage Piet/Corvair) let
me know.

It must be newbie day. I just spent an hour going over current and past e-mails,
amazing. I do have my first question though. I'm setting up my rib jig and am
confused on how the trailing edge finishes. Is it simply squared off with the
capstrips ? What about the wedge material, size ? Does anyone have a picture
and/or advise ?

I think I dropped you a PM, but I'm not sure. I'd love to see your project, but
my work travels keep me away most of the time. I'm actually working in the
DTC area over the next couple weeks, so maybe we can hook up at some point then.
We should talk more offline.

Don't worry about it until all your ribs are finished, just leave the
capstrip extended an inch or two beyond where the rib will end when
finished. Then you can clamp all your ribs together and cut the trailing
edges square all at once (and even up the leading edges of all the ribs as
well). I assume the "wedge" you are refering to is the trailing edge piece
that runs the full length of the wing. It is shown on page 5 of the plans as
a 1 1/4" wide strip of wood. Mike Cuy just posted his solution to this a day
or two ago, he use a piece of Home Depot Fir trim molding ripped to the
wedge shape. You can find his picture of this on the archives.
Good luck

Rick, et al,
Thanks!
Yeah here in Santa Fe our pattern altitude is about 7200 ft. I found
someone flying a Piet on the web up the road in Salida Co with a turbo
Subie!
Thanks for the tips! I started an RV9 when I was in Dallas and life/move
put that on hold, then I started a Cozy Mk IV but decided to wait until I
could build a Velocity. Now while I'm waiting I'll build a Piet! I like
the idea that it's a series of simple systems, affordable, affordable and of
course affordable. It'll be nice to try something fun, classic and did I
saw affordable before I start a cruise-mobile.
Thanks!
Bob

Hey Bob
Welcome to the Pietenpol clan, I am in Castle Rock CO, and little South of
Denver. You can come by any time if you make it up North sometime. Thats
quite a leap from a Velocity to a Pietenpol (kind of like going out to buy a
new 2008 Corvette Z06 and coming home with a Model T) but it sure will be
cheaper and easier. I am building a long fuselage Piet with a Corvair.and
three piece wing (which is how most people build their wings). Flying out of
a higher altitude like me you probably will need more than a C-65 for an
engine (as most people use), but their are lots of options. The best place
for recommendations and ideas are the archives of this newsgroup. Here are
my standard newbe recommendations:
- Order the basic and three piece wing plans (maybe long fuse plans) from
Don Pietenpol (full size rib plans aren't needed IMO)
- Join up with the nearest EAA chapter (can find list of all of them at
www.eaa.org)
- Order all four Tony Bingelis books (off EAA site)
- Order the Mike Cuy Piet DVD and watch multiple times
- If you can attend the next Pietenpol flyin at Broadhead WI the weekend
before Oshkosh to see lots of Piets and builders
- Order read Chet Peeks excellent "The Pietenpo Story" book (search Chet

Hi Jim,
Here's how I did my ribs.
http://www.flyingwood.com/index.asp?page=8&filter=0
One of these days I'll push a piece of spar through them, and sand the
trailing and leading edges flush while they're all together like Rick said.
Getting started is the hardest part. Welcome to the group.

Jeff,
Felix my GN-1 has 3 bolts coming up thorough the aft wooden cross member,
the one where the aft legs of the LG hits the lower longerons. I believe
they come through the steel channel, can't tell for sure because the bottom
of the fuse is covered with fabric so you can't see the channels. The
front wooden corss member has 2 bolts coming up through it, one on each
side. The plans show 3 holes in each of the steel channels.

Peter, Just wondering why are you thinking of changing away from spoked wheels?
I have 8.00 X 4 on Felix the GN-1 which I like, but going to use 21" spokes wheels
on the Piet I'm building.

Hi Guys,
I am thinking of changing my wire spoked wheels for normal aircraft type wheels.
What tires sizes are you guys using? 15-6.00x6 or 8.00x6?

1. I recall reading advice to use somewhere around 2:1 to 3:1.
2. Oddly, bringing this subject up today caused me to google it, having never done
so in the past - it's been a while since I used this technique (ammonia water
for those that don't know is an ammonium hydroxide solution, very alkaline,
which is created by when ammonia is dissolved in water: H2O + NH3 NH4OH).
I found references sugesting it does nothing more than water and that you had
to use anhydrous ammonia to have any effect. Yet.. when I've used ammonia water
with strip balsa and light hardwoods, I swear it made a whole pile of difference.
I guess when I have a half hour with nothing else to do, and I remember to do so,
I should do some side by side comparisons under controlled conditions, or as
controlled as I can practically make them.
Anything I have read on ammonia and wood, indicates that there is no sacrifice
in properties once the extra water and ammonia has dried/evaporated out - it softens
the lignin and has an effect on the cellulose as well, allowing them to
be deformed like hot plastic. When it is gone, the wood is back to what it was,
albeit in a different shape.

That is a good question. I find the wire spoke wheels do more than
anything else to add to the "ramp appeal" of the Pietenpol. Peter must
have a good reason.

Thanks much. The ancient set of Grega plans that we have show various
approaches - some figures show bolts, others don't!
On your front crossmember, about where are the two bolts? Out towards
the longerons or more--or-less dividing the crossmember into 3 equal
spans?
Thanks,
