Front Skylight mounting.

[schu]

Builders,

What did you guys do to attache the lexan in the front near the windshield? Did you just run a screw through the a fairing strip, then the lexan, the u channel, the windshield, then just put a nut on the back side? I suppose that would work.

I guess you could make a u-channel facing back to capture the lexan. Weld it on?

Curious as to what others have done since I'm starting on my skylight.

I can't find a good picture at the moment but my install is basically following Steve's Aircraft Skylight STC for the PA20. The front is attached with an aluminum 'U' that has one long leg. The short leg gets placed in the windshield 'U' and the long leg goes on top of the skylight. Screws/nuts are used to fasten the long leg of the 'U' and the skylight together.

Source for aluminum u? Or how to make it?

[whee]

We will make ours the same way we made the steel windshield U...but I can't remember exactly how we did it. We either bent it in a brake we made or formed it around some 1/4" rod.

Installed Steve’s skylight on my Pacer... installed the windshield into the “U” groove.. the skylight was installed using primerless urethane windshield adhesive around the circumference. Shaped aluminum strips for the leading and trailing edges of the skylight. Looking for that picture....here’s the fit before gluing the skylight to the structure.

Here is how I did it
The U is 5052. 0,050 and the long leg 60 mm the short 30mm
The short leg in the windshield U and the long leg on top of the skylight
Fasten with screw and nut through the U and the windshield U

I'm thinking I'll have my skylight front terminate flush with the windshield rather than sit on top of it. I believe this is how Battson did his, at least from what I've been able to see from his YouTube walk-around. A fair bit out from that though.

This would involve attaching an aluminum fairing to the windshield channel that extends aft to overlap the skylight, then bolting through that to secure to the lexan.
