Windows and Canopes
Lynn on slippery side windows:
I find that the problems with keeping the side windows closed or partially open is that over the years the hardware originally installed in the Ercoupe is broken, or missing completely.
There was originally a small spring steel strip riveted on the inside of the window channel which applied a small amount of pressure on the window through the window welt.
The pressure could be increased by using the screw(#8 x 32 ) to add pressure to the side of the window, which would hold the window in place. Once the metal piece is gone, the screw only can put pressure on the plastic through the window welt (no good).
So the solution is to glue a piece of stainless steel to the outside of the window welt between the welt and the screw. Then when the screw is turned in it adds pressure over an area of the welt which holds the window in the desired place.
The stainless piece should be about 1/2 " wide by about an inch long. The original piece was only about 1/4" by about 2 "long, riveted to the inside of the track on top. I have tried using a piece of aluminum, but it does not hold up to the pressure of the screw. The stainless will withstand the pressure and last a good while.
I also have made replacement screws by adding wing nuts to a long # 8 screw (yeah I am cheap)
