Last year the company I worked for decided that after 115 years in business it
was time to close. Being in the building materials business and the state of the
economy, there was no place to land. I put my safety background to work on the
grain business. Very fertile ground for a safety person. Look forward to meeting
you at Brodhead and we can exchange information. If need be contact me off line.

John,
The Hatz I was looking at has a 0-235-C1 and I looked up all the ADs and
SBs on it. I've attached it for your review.
The AD search page at
http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgAD.nsf/Frameset?OpenPage
is pretty easy to navigate.
Enjoy!

is very clear in that it requires 2 hardened steel gears. My log book lied. It
was written that the oil pump AD had been done and it had not. Make sure you
knock the sludge tubes out of the crank and clean the krud out. If you are very
careful you can reuse them as it is experimental. I bought an oak dowel the
same OD as the sludge tube and sanded it to fit. Measure them to make sure they
are still a press fit before you reuse them. If they are not removed and cleaned
odds are very great you will have bearing problems as the oil distribution
goes around the OD of those tubes. They make like a centrifuge when the engine
is running. Some of the krud the filters miss is c

Subject: Pietenpol-List: Hangar work
John, I have been through all of this before. Any airport that accepts
Federal funds cannot preclude an owner from performing his own work. That
being said, they can also place reasonable safety restrictions on your
activities. Open flames or electrical wiring that poses a potential fire
hazard are probably reasonable. I know that if I was to be responsible for
every airplane in my hangar row, I would be pretty damned careful. Also,
when I think of some of the doofuses in my hangar row, all I can say is they
better never burn up my Travel Air and Pietenpol for their stupidity! I
KNOW they are not insured enough. Nonetheless, there are some who store
fuel in plastic 55 gallon drums in their hangar. I'd hate to have to kill
them!!
If I can help in any way, please contact me,
Gene

The list is slow this morning, so I will put this out for comment and general information.
Don't know how others have handled(pun intended) this problem. I thought
a long time about how to reinforce the handle the pilot grabs as he gets
in or out of the back pit. My Grega has a similar handle but I can't look inside
the C/S to see how it is reinforced. The brackets are .058X5/8 tube and 16ga
plate. They are screwed to the handle through the ply and spruce and bolted
to the C/S spar(vertical center only) with AN3 hardware.

Very nice work, Skip! Nice to see you making progress.
Can't see all the detail from the pic, but my only suggestion would be to
give the handle as much mass as possible, giving you more glue surface to
the cutout. That may be the case, already, and I'm not seeing it in the
view.

Thanks Gary,
The handle is made from some 3/4" flooring I think is Teak. It should have about
8.25 sq" of glue surface. I hope that and the screws will take the stress.

Skipp, that certainly looks more than adequate. That is certainly a
very
high load area as the pilot puts his entire weight on it during ingress
and
egress. I made mine as a =BC=94 plwood box, going to a laminated spruce
bow as
shown below, and I believe you could use it to pick up the entire
airplane.

I ended up building a flap in the rear of my center section to make it
easier to exit. I also have an active Sky-dive business at my home
airport, so I thought it would be a good idea to be able to look
straight up to make sure all the jumpers were down before I took off.
I didn't put any handle at all on my center section. The two rear
cabane struts make a perfect place to grab to pull myself out of the
seat, and allow me to use both arms for the effort. Your center section
looks beautiful, but I think it would look even better without the
handle, and the added stress it puts on all that 1/4 x 1/2 inch
structure. Just my $.02

Howdy, low 'n' slow fliers;
While I've been sitting here twiddling my thumbs waiting to find a house and hangar,
I had a
nice email from Doc Mosher, forwarding another email to me. Seems that the folks
up in
McMinnville at the Evergreen Aviation and Space Museum (home of the Howard Hughes
'Spruce Goose') are about 80% progressed on building a Piet for the museum! I
don't know
if their intent is to fly it, but I sure hope so. And knowing the quality of displays
in most
museums, I'll bet their Air Camper will be a beauty. Doc forwarded the email to
me because
the builders were looking for one of the brass data plates that I sell, and I'll
be donating one
to the project (they are all volunteers and everything is done by contributions).
I'm anxious to start some low and slow flying up and down the I-5 corridor, if
I can just get
Scout up here. But being the loyal husband that I am, I've promised to focus
on getting us
into a permanent residence first, and then worrying about airplanes and hangars.
I hope
I get some brownie points or a gold star by my name or something ;o)

I know it's not a truly all wood idea- but what I ended up doing after looking
at the wing flop I had with my project a while was- scrap it and get some light
1/2" galvanized EMT I think it's called conduit. kept working it into a bow
till I had a curve I liked that went from one root rib to the other on the wings.bent
some light steel to make clips that could be screwed into the rib tails
so it all faired in.and made 2 short ribs from Aluminum sheet- (actually cut
em out from some surplus aluminum signs I had)that fit the back of the rear center
section spar and tapered to the width of the EMT. left tabs on them that
lapped the top and bottom of the conduit and riveted them to it with stainless
steel pop rivets. and a couple bolts from the ribs to the spar give lots of
strength. also used a straight piece to bridge across the bow in the center with
enough width and room for a grab handle - brazed it on after fitting the ends,and
after final installing the wings and rigging- doped and fabric covered
the area as well as the root gaps on the wing.looks like a one piece wing now.
would take a little more work to get the wings off but unless I need to do serious
work i don't plan on that anyway.did away with gap seals and came out pretty
clean and simple-I wouldn't want to swing my 210#'s from it but sure feels
strong and solid using it to steady myself getting in and out.not to Grega drawings
but it works for me Raymond

Hey all,
Not sure if it'll ever happen, but a move to the high country of Colorado
MIGHT take place one year in the future. The closest airports are Buena
Vista at 7900 feet and Salida at 7400 feet elevation. (8000ft and 7000ft
long respectively!)
My piet has standard wings, but a new C-90 turning a Cloud Car prop. The
approaches to both these fields open as they're in the middle of the same
valley.
Do you think I'd be okay?
I remember "Mountain Piet" was based out of Buena Vista, and with his
reduced Subaru, he did fine while it flew, though it was turbocharged.
I'm sure I could find lower fields, but they start getting farther and
farther away, which makes things less enjoyable and convenient.
