School Project -"doping"


What you see here is a control surface (i.e. rudder, elevator) of off "who-knows-what." What you don't know is what we started with. A little frame made out of tubing. You can faintly see the outlines of it here in the picture.
  1. We.....:
  2. 1. Covered the frame with Fabric and glued it to the frame at the edges.
  3. 2. Used a "clothes Iron" to tighten the fabric so that it wasn't sloppy.
  4. 3. Stitched the ribs with riblacing.
  5. 4. Applied many coats of Nitrate and Butyrate "dope"(don't ask me why it is called dope, although you start feeling pretty loopy if you don't wear a respirator.
  6. 5. Applied several coats of Silver "dope" so that the fabric reflects sunlight and doesn't deteriorate pre-maturely.
    6. Applied Polyurethane (the red color)
  7. Painted on the fancy stripes and letters.

*All spraying was done with a paint gun. these make for very nice paint jobs, but there is a technique. I had so many paint runs in my first coat, it wasn't even funny.*

Note: PK-KJB: PK is the Indonesian symbol, KJB stands for Kars, Jake and Brent. The three guys who worked on the project.
