I don't know if you are trying to go Native American with that Osage orange, but
that is among the materials used for bows in this country. That material in
your useage adds a nice touch, and no other Piet will have it, or the story that
goes with it. If it darkens, so what?
It sounds like you have some good sources for stains and coatings here, so you
are well positioned to go with what seems best to you. Please send pix of the
finished product to share with all of us.

| Subject: | My first wing is covered and stitched! |
This sure is an exciting part of Pietenpol building. I just finished
putting the last rib stitch in my right wing. Now all it needs is
surface tapes and paint. I've attached a few pictures of the wing
rotator jig I made up using two Work-Mate benches. By using this device
I can rotate the wing to do the covering, stitching, and eventually
painting without needing any help. If you look closely on the wing root
end I welded a sheet metal (4130X0.025) disk to the axle that can be
used to hold the wing in nearly any position by tightening the hold-down
vise built into the bench. To get clearance for full rotation the axles
are centered on the wing, which makes the leading edge much heavier than
the trailing edge. Honestly the disk brake was a bit of a
disappointment, but I can use a sawhorse, or various things to hold the
wing where I need it.
I bought a nice rib stitch needle, but lost it somewhere. I made a
replacement from a piece of 3/32 brass rod from the hardware store for
$0.99. Just hammered one end a little flat, drilled a hole in it, then
sharpened the other end and it works just as well as one you can buy
from ACS for 16 bucks. The rib stitching is actually not that bad, I
was able to do the whole wing in 3 evenings working alone. I used 3-1/2
inch spacing except for the inside 4 ribs which got 1-3/4 inch spacing.
Its a little overkill, but made all the stitches line up all down the
length of the wing.
I'm using the Stewart System glue, and got a copy of their covering
videos that are really great. The making of the cable exit covers is
detailed in the video, and I was able to make them up pretty easily. I
had one problem in that the upper pulley for the aileron cables was
rubbing the fabric. I was able to make a "blister" out of the bottom of
a Coke can that gave the clearance I needed. I'll attach a picture of
that on a separate e-mail

This is a shot of my aluminum cable exits, and the blister I made from
the bottom of a Coke can to give clearance for my aileron pulley. Its
amazing how many different problems you have to solve in a project of
this magnitude!

Good idea, Ben; but we all know it's a Coors can!
It appears that you do not have brand new turnbuckles. Do you have a source
for used ones?

These are new turnbuckles that have been laying around a while. These
came from a Nieuport project I bought, but I believe they came from B&B
aircraft supply. I bought some from them at Oshkosh for around $8 each
