100 years of progress from the 1903 Wright Flyer to the UltraCruiser.
First ribs I have built - one for a museum and the other to fly!
Hole is flanged.
Nose rib modification suggested by Charles Snyder and also the
Aviation Magnet leader at Washburn High School.
Hole not flanged yet.
"Ivory" fluting pliers per Australian Peter Denny.
Actually you buy these from Avery Tools.
Hole flanger die built by Dale Johnson, lead builder on the
1903 Wright Flyer for the State of Minnesota
Correct position for fluting rib flanges.
Wrong side up!
Not shown in this view ts the word "OVER" written with a
Sharpie pen on the "bottom" side.
Note: crimps have to be carefully placed so as not to interfere with verticals.
Also note the steel drill guides, one for each vertical channel.
These were built from the steel inserts in scrapped Pendeflex folders.
In the blown up image you will see the electric drill. Air drill not needed here.
This is not a toy!!!! .... 18 inch bending brake
With the blown up image you can see how I have drilled holes in
which pins are placed to provide automatic depth gauge for the
one-half inch and one-quarter inch flanges.
The extra holes indicate measuring or drilling error.
Availble from Harbor Freight for $34.99
Note: I built two custom brakes and junked them due to poor results.
I borrowed a brake from my EAA chapter. It was sprung and no good.
I now use a 48-inch brake at the airport for larger work.
