In wrapping up my glider project of 20 years or so, and in my effort to remain true to the plans, I have created a squeak monster.
First glider info. Prue Super Standard sailplane. 15 meter span, all metal monocoque stressed skin construction. The aileron control push/pull rods are 6061T6 3/4" in diameter and are about 17 feet in length. The supports for the control rods, as they run through the wing are made from linen micarta straight out of the early 60's. The supports with 1" diameter holes were riveted to the ribs during initial construction. When the control rods are moved it is squeak city. So much that I have pulled the drawings out to prove that this method of construction was called out. I had lubricated the rods and supports with Aeroshell grease during the initial construction but it didn't make very much difference. Final inspection this late July, she hasn't flown yet. Any ideas or suggestions are welcome. It may just be earplugs....
