It's One Of The Early Steps Of Building An Airplane
By Maria Morrison
Now, anyone can learn how to ribstitch, cover, or poly-brush an airplane with the help of a group of people in a tent by the hangars. Here about 10 people teach about the various stages of building and aircraft when it is just a couple pieces of wood.
First, you have to do covering. This is where the wooden frame gets covered with fabric. Fabric is glued down and then smothered with acetone. this helps it stay forever. Once the fabric is all glued down, the people use a common household iron to shrink down the fabric and take out wrinkles. When the fabric is done, it can be shrunk by 12 percent.
The next step is the poly-brushing. Poly-brush is a pink liquid that fills the weave in the fabric. While the poly-brush is still wet, they put on the finishing tapes, which are long strips of fabric over the ribs.
After the poly-brushing is dry, people put chalk lines on the piece for ribstitches. The space between the lines depends on the type of aircraft, but they are normally 1-2 inches away from each other. Then, thin tapes are laid down in the middle of the finishing tapes, directly over the ribs. Holes for the stitches are pokes next to the tapes on the chalk lines.
Last is ribstitching. This is where the stitcher takes a long needle and a waxy string and threads it through the holes, tying special knots along the way. Stitching is required over the ribs to stop the fabric from bubbling up during flight, but it is also good to have anywhere that is out in the wind.
The booth had a Corben Baby Ace structure on display, along with many covered pieces of a J-1 and a Tripacer.
