| Subject: | Small quantities of spruce for sale- Weldwood glue |
Steve,
Aircraft Spruce has for sale their "bargain bag" of spruce. This consists of
a pretty good size bundle, many pieces 5 ft long, of all kinds of spar and
cap strip cut-offs that they can't sell. I actually bought two of these along
the way and I am so glad I did. I think I paid about $12.00 each for them at
the time. I would highly recommend it. I made many many parts from this. Of
course you have to have a way to cut and plane them to the size you need. I
think Wicks has a similar bundle for sale.
I'm glad to hear that the Weldwood Plastic Resin glue held so well. It is
the glue that I used to hold the laminations of my prop together.

| Subject: | Re: Propeller pics soon |
John,
Stay tuned for the photos of my just completed prop. This for me has been
without a doubt the most rewarding part of the whole project so far. Last year
at OSH I observed an old-timer (Jerry Thornhill from Hampshire IL) do a prop
carving demonstration using all power tools- electric chain saw, 7 in. angle
grinder w/ rubber backing pad and velcro sanding disc, and then finally a 5"
DeWalt vibrating/rotary sander. This is the prop that is on the Bleriot engine
that was run-up daily at Osh this year. The only hand tool I used was a
metal file to knock off the high spots on the summer wood on the ash that I used.
It looks very nice but now has to perform with some good thrust. The
dimensions are 76 x 46 pitch. I arrived at this pitch by asking around and looking
at the archives. For those who don't know I am using a model A. Yesterday I
drilled the bolt holes. Very scary but all worked out OK. Now I have to counter
bore out the back side of those holes to accept the Continental-style prop
hub that I bought from Ken Perkins. Very exciting times here at this Pietenpol
factory.

Funny thing is your seat was "built to the plans". If you look at drawing #4
the side view shows both front and back seats built exactly the way your
broken seat is built. I was nervous that the "Piet Gods" would strike me
down when I did the *blasphemous *act of modifying the design to set each
end of the front-to-back pieces on top of a vertical support on both of my
seats.

Sory to hear of your seat-failure.- At least it should be an easy fix.
- As far as being a true purist, I say we reserve the right to get smarte
r.- It's a great design but some tweaking here and there can go a long wa
y (for better or worse).- Just be sure to get all the varnish off before
re-gluing anything.- That will be the most uninjoyable part of the repair
.- I usually use the side of a good wood chisle with a pulling motion, or
a piece of glass to shave off the old finish.- Has anyone had any luck w
ith chemical strippers on airplanes?-(for repairing glue joints already v
arnished)-The unknown reaction, (if any) to the glue scares me.- Good l
uck and keep yer chin up.

The front seat in 41CC failed due to the nose-over, in a peculiar way. Forward
impact by the pilot's feet jammed the seat forward and separated some of the
joints. When I rebuilt the front seat, I found much the same thing as you guys...
the glaring need for some uprights to support the ends of the seat pieces.
Since getting into the front cockpit almost invariably involves standing on
the front seat, those little uprights are really needed. It's amazing what a
couple of 4" long pieces of wood will do.
Picture of my seat framing is at http://www.flysquirrel.net/piets/repairs/seat.html, second photo from the bottom, and if you're a Piet purist, save yourself a rise in blood pressure and don't look because my seat is a departure from plans. Oh, and you'll also notice in the picture that 41CC has the tailwheel steering cables run all the way from rudder bar to the tailwheel, as per plans.

Oscar,
The best part of your seat repair was without a doubt the notation you put
on the back. Without His blessings we would all be in trouble.

I saw in the plans that there was no support for the rear of the seat,
and I think it is one of those points where the plans are incomplete.
My correction for the plans looks exactly like your fix, I added the two
uprights on the sides, as they should be. I also added a "saddle
gusset" to the rear of the center brace. I took a number of photos of
the seat, but I am on the raod now. I will attach some photos of my fix
for the seat when I get home.

| Subject: | front seat repairs |
Here is my installation of the front seat.I've never posted a picture
before.hope it's not stripped!
Front seat rear support. After seeing Oscar's pictures, I think I will add
another support to carry the sides.
But I did add gussets on the sides and center to help distribute the 'load.'
Front supports are wide enough to help carry load.
Note: Gussets.

Subject: Pietenpol-List: front seat repairs
The front seat in 41CC failed due to the nose-over, in a peculiar way.
Forward impact by the pilot's feet jammed the seat forward and separated
some of the joints. When I rebuilt the front seat, I found much the same
thing as you guys... the glaring need for some uprights to support the ends
of the seat pieces. Since getting into the front cockpit almost invariably
involves standing on the front seat, those little uprights are really
needed. It's amazing what a couple of 4" long pieces of wood will do.
Picture of my seat framing is at
http://www.flysquirrel.net/piets/repairs/seat.html, second photo from the
bottom, and if you're a Piet purist, save yourself a rise in blood pressure
and don't look because my seat is a departure from plans. Oh, and you'll
also notice in the picture that 41CC has the tailwheel steering cables run
all the way from rudder bar to the tailwheel, as per plans.

How much do you need? I might have some extra I can send you.

As a side note, I now need a very small quantity of 1/4" spruce
plywood and a few feet of 1"x1" spruce stock. Where would be a good
place to find such a small quantity? Should I just try to find some
from a local builder?
Thanks,

I had an interesting failure on my airplane today. I was taking a
180 pound passenger up for a ride, and about halfway through our takeoff
roll, the rudder locked in place. I immediately throttled to idle and
rolled to a stop. Turned out his seat had broken going over a bump, and
fell directly on top of the rudder pedals, which then supported all of
his weight. Could've been dangerous during a landing, as I had no
rudder control.
The interesting thing was the mode of failure. The seat was
improperly made, the 1"x1" stringers under the seat that run from front
to back on the seat bottom did not sit ON the rear support. Instead,
they butted up against another 1"x1" that sat on the rear support. They
should've been extended beside the rear stringer, so they would've
carried the load all the way to the rear support. I hope that makes
sense, if not let me know and I'll clarify.
The interesting part is that the glue did not fail, the wood did in
almost all joints. It even split one of the 3/4" x 1" stringers nearly
in half. I've been wondering how well the glue joints maintain their
strength over time in an airplane like mine. Hopefully the pictures
will explain better.

(Sorry about the blank post)
The paper cutter I purchased from the Michigan State University "Surplus
Store" arrived while we were gone this weekend. Sturdy wood table, steel arm
for $29 + $11 shipping. I unboxed it this evening and I am very pleased. The
table is not perfect (nor did I expect it to be), but it is flat. The blades
are actually still relatively sharp. They have surface rust from being in
storage, but no pitting. I cut a small test piece of ply, and it worked
great. A little clean-up and a light stoning and it will be good as new.

So, if you are looking to pick up a used paper cutter and can't find one, I
would suggest calling your local/regional University or School District, and
see if they have a storefront or department that is in charge of disposing
of their surplus. A Google search for the same may also get results. Have a
good night,
Ryan
