Fitting windshield

[rosslr]

Hi Dave,

I am doing this at the moment too - I went flush after seeing that I would need to put a spacer between the cap strip and the windscreen to make sure the wing cleared it. Not that it would have been a big problem. Dave S makes some good points in favour of the overlap though. We intend to have a cover for the odd occasion it might be parked outside and rain is an issue.
Hope you are starting to enjoy an nice spring over there - Wimbledon and cricket ..... Ahhhh!
any photos of where you are up to Dave?

cheers

I overlapped mine, just under 1/4". Thought it looked a little better, more material around holes, and somewhat better rain seal. I did have to taper the underside of the overlap to make sure the wing slipped under it without pressure.

Any photos of what you are talking about, I am just getting ready to mount the butt ribs and perhaps there is a choice how there adjusted at this stage.

Mount your butt ribs as per the manual. They should be flush and aligned with the number one rib on the wing.

The discussion has to do with how to trim the windshield along the butt rib. The manual instructs you to trim the windshield flush with the butt rib with no overhang. Some builders trim the windshield a 1/4 inch or so beyond the butt rib. The overhang covers the gap between the butt rib and number one rib. It can cut down on air and rain leaks. Care must be taken if you elect to have an overhang when unfolding the wings. The number one rib must slip under the windshield overhang. It is possible for the number one rib to snag or pinch the windshield overhang and cause a crack in the sky light portion of the windshield. You might also get some chafing of the fabric on the top of the number one rib.

An alternative sealing method is to trim the windshield flush with the butt rib. Glue in 3/4 inch round weatherstrip just below the cap strip on the outside of the butt rib. When you unfold the wings there is no chance of snagging anything on the windshield. The weatherstrip compresses between the butt and number one ribs to seal the joint.

Thank you for the response, I did some research on this site and did find some photos. After looking for this info for a while I am starting to understand how to navigate this site a bit better. A lot of good info here, just need to find it.
