RE: [ercoupe-tech] Stripped thumb screw

[Iflysmodel]

Hey Mac: I have been out of touch since Sunday, so someone else may have 
mentioned this. I find that a lot of people replace the window welts, but do 
not put anything between the welt and the thumb screw. This can/will damage the 
window if you tighten it enough. I always put a piece of aluminum between the 
welt and the screw. This gives something for the screw to put pressure on other 
than the window. And allows you to tighten the screw enough to hold the window 
in whatever position you want.
