Brief Description: Form for Landing Light Lens and Lens
Formed the modified wing rib using two segments of 1/2 inch aluminum tubing attached to the rib tip with 1/8 inch pop rivets. Completed a seconded modified rib to match the first. Attached the two ribs to each other with a pair of 1/2 inch angles 6 inches long. Cut a 7 by 12 inch rectangle piece of .020 sheet aluminum. Attached the bottom edge of the sheet to the modified wing ribs with a 1/8 inch pop rivet in each of the ribs. Rolled the sheet up over the wing tips and pop riveted the top to the wing ribs. Measured each of the rib stubs to equal lengths and cut off each rib at the marked locations.
Set the oven to 300 degrees and placed a 12 inch long 2 by 4 wood block in the oven. Removed the protective film from each side of a 8 by 12 inch sheet of Plexiglas. Laid the Plexiglas over the wood block and left to soften. Heated the wing form with a heat gun and using mitts removed the sheet of Plexiglas from the over and place it over the wing form. The sheet was not soft enough to form over the wing tip. Raised the temperature of the oven to 350 degrees and placed the sheet of Plexiglas back into the oven. Removed the sheet after about 5 minutes at 350 degrees and laid it over the wing form. Formed the Plexiglas over the form using the mitt and held it in place until it cooled. Repeated the process for two more sheets of Plexiglas forming a total of three lens for later processing.
