Hey Santiago
Attached a couple pictures of the ply wedges I added to mine to get two
parallel surfaces for the two bolts.

Jim,
I am not near buy, but feel we "GN-1 builders" need to hang together. I have come
to the conclusion that there are those "purist" out there, (not all) who don't
see "the advance variation" of the "father and fore runner" of home built
aircraft as "true".
Still, GN-1 builders have needs, interests and a willingness and desire to build
a good safe project.
Anyway, i am 80% done and as the ole saying goes, 80% to go. Still, my wood frame
fuselage is pretty well done, the Corvair needs to be built and my wing are
done. everything needs to be covered. mine sets on a cub type gear, with brakes
and tail wheel.
Where are you, with your project?
Gene

All of the points that Chris raises are valid. My feeling was that the new
setup is an improvement over what was there before, not that it was an ideal
solution. I will note, however, than in the nose-over the rear cabanes
remained intact and it is the X-braces for those cabanes that the attach
point is anchored to. The cables are 1/8" and are tensioned pretty well,
but if something bends or buckles they could go slack, yes.
The best solution that I've seen is the wishbone-style welded tube fitting
that the UK Pietenpolers pioneered. It installs inside the boot cowl that
encloses the flight instruments and is a really sturdy piece of work. One
example is G-BYZY, one photo example is

Even old Pietenpol himself wasn't a purist.He would change things to get
the best,otherwise he would still have flown the Jenny he orinally
started with and not have changed anything.Why change from an old model
A engine to anything else etc.Need I say more?

| Subject: | Re: front cockpit shoulder harness attach |
Gene,
Thanks for your good input. Oscar has answered your questions about damage in
the hard landing, indicating that his "imoroved BPA shoulder harness assembly"
would likely have worked quite well in his hard landing. (We all agree some
things might well have been stretched.) He has also provided the pix of an alternative,
the more robust UK shoulder harness attachments. But you have raised
a question about the survivability of the cabanes and the front cabane-to-firewall
connection. I'd like to add to that.
Oscar's plane had a hard landing, but William Wynne's had a crash landing (steeply
from 70 feet up), and the Heim connectors or whatever he had, designed to
resist PULL in flight, would not and could not resist COMPRESSION in a crash.
Wynne has suggested building the assembly with tubing and stout connections to
prevent BOTH push and pull. This is more important, as he has pointed out,
when the gas tank is in the wing, as things can move, leak, and flame, as they
did to him. As you may know, he had several surgeries as a result of burns.
Ideally we might go with something more adustable and less permanent-- Heim and
lighter tubing-- to TEST the final location of the wing for CG purposes, and
then install a more permanent and stouter final assembly. Both this tubing forward
and the tubing of the two shoulder harnesses' attachments add weight that
BP did not have. Of course, as others have pointed out, we are supposed to
make the planes both light and strong enough to fly well, not strong and heavy
enough to crash well. To me, though, these few pounds seem like good ones.
These are the last safety measures you have in a crash.
I might have enough appropriate tubing on hand to estimate the total weight. Maybe
someone else already knows.
In any event, I'd like to hear both data and opinions of more established Piet
builders/fliers. Thanks already to you and Oscar for this discussion.
Regards,
Tim in central TX

I know there has been a lot of discussion in the past about where to purchase parts
for wire wheels and such. I am just wondering what is an average cost per
wheel ready to roll if you went the route of buying motorcycle rims, making
a hub, buying spokes, buying tubes and tires, etc...
I am leaning towards getting the kit from here... http://www.airdromeaeroplanes.com/Default.asp?page=76 and am just wondering if their price tag is in the ball park. ($495.00 for both)
Thanks!

Invoices for tires/tubes/rims/spokes/etc Those invoices are for 2 sets, (enough
for 2 projects) so divide all the costs by 1/2:

Another question might be what is the weight difference? The Airdromeaeroplanes.com
kit is 36 pounds for two complete wheels with tires and tubes.
What do some of the other complete wire wheels weigh?

Dan,
I recently finished my wheels. Here is my information on them.
2.50" wide x 19" Drop Center Chrome Rim, 40 hole $65 each
Chrome Spokes $40 per
set
4130 Tubing for Hubs 2" o.d. x 0.120" wall $7 per foot
4130 Flat Steel for flanges 0.090" x 9"x9" $5
Oil Impregnated Bearings $20
Total for two wheels ~ $225
Tires, tubes and rim bands $45 each
Paint for hubs $05
Total cost of completed wheels w/ tires (for both) ~ $320
disclaimer: These have not flown (or landed) yet.
I also considered the Aerodrome wheels. When I inquired, I learned that the
hubs were made for a slightly smaller diameter axle, and an 18" internal sleeve
is inserted inside each axle end to increase the strength or stiffness. I am
not questioning the design, only sharing information in the event you already
have the axle. I made the phone call and they were very kind. I simply chose
to fabricate my own.
