Windshield Moulding

Re: Windshield Moulding

And now I'm really confused about which way the rubber molding should face. Should it be as A or B in the attached diagram? Seems to me like the beaded edge of the longest leg should go over the top edge of the fairing, like A...

Joel, I'm pretty sure it's "B", but I am not nearly an authority on historical accuracy as much as several others here.

Re: Windshield Moulding

The fluting was a process during the Feris era (F-19) to get the windshield band to conform to the curve, IF it is on a BC12D then it is a newer band from the Feris or later factory, an other way was to fit the windshield , then fit the band to conform to it. Replacement just takes a bit more fitting and trimming.
WE use heat , warm shop , heat lamps, or sunlight on windshield , beyond warm sandbags on the windshield , slot the side of the windshield , larger holes on top, the windshield just kind of floats around when installed correctly. The top is bolted in loosely. The hooks with rubber almost touch the windshield , they are there to prevent windshield caving in beyond Vd plus 10%. Wish I was there.

Re: Windshield Moulding

Hey Joel,
Just to make things more confusing, I need to tell you that the Tim that wrote about the orientation of the rubber (me, N96872) is not the same Tim that wrote about the corrugated trim piece (N29787).
Also, I don't know anything about the correct installation. I was only reporting how mine is installed (which, if I interpret your sketch correctly, is B), with the long leg inside of the cabin. I've never installed a windscreen. I don't know that mine is corrrect.

Re: Windshield Moulding

On second thought, and after looking at all my photos of other BC12-D's windshields, I remember that I've never seen that fluted edge on any other BC12-D windshield fairings. And Tyler's ship is a bare-bones Ace model, without the left door, etc. Is it possible the factory left that fluted edge on the Ace fairings, but removed it for the BC12-Ds? I assume the fluting has something to do with keeping the edge from wrinkling as the tooling stamped? rolled? the compound curves into the strip of aluminum?

Re: Windshield Moulding

The "fluted" part gets done at the time of installation, each airplane & windshield are a bit different so the flutes vary. At one time it was only a smooth curve that followed around the bends.
Even I got confused by description , the "proper" rubber channel will have a longer part inside the cabin and it does go over the glare shield , it is put in place with a tool shaped like a small hook. Wish I was there.... pictures anyone?

Re: Windshield Moulding

Can anyone help resolve contradictory information about windshield installation? I've got a new windshield from LP Aero Plastics, the rubber molding from Tom Baker, and a new boot cowl-to-windshield aluminum fairing strip from the factory.

But now I'm confused about the orientation of the rubber molding. Tim wrote this referring to the photo above of the molding cross-section:

Mine is installed with the long leg on the inside of the cabin. So looking at your picture, starting from the bottom:
Your thumb would be inside the cabin.
Then then long leg of rubber.
Then the windscreen.
Then the short web (middle part) of rubber.
Then the aluminum trim.
Then the short leg of rubber.
Then your finger which is on the exterior of the airplane.
On mine, the long leg of rubber kind of flops around on the inside of the glass. I'm not sure why it's so long.

But Tom Baker told me just the opposite:
Windshield fairing (thumb in photo).
Long one-inch leg of rubber, with the bead sitting on the top edge of the fairing.
Windshield.
Short half-inch leg.
Other short half-inch leg of rubber bent up, perpendicular to windshield, sitting on top of the glareshield.

And can anyone confirm what Tim wrote in the separate 8/08 thread called "windshield rubber weatherstrip":

"The factory has them also, just remember to trim off the corrugated part of the strip, I have seen several aircraft where it was not trimmed off and it rubs the windshield. Tim
N29787
'41 BC12-65"

The top half-inch or so of the factory fairing strip is indeed fluted, but I assumed that was how it should be left. See the attached photo of Tyler Foster's serial no. 8015 at Oshkosh 2008, which seemed very original. Fluted fairing strip, with the bead of the long leg of the rubber molding over the top edge of the fairing.

I'm a little anxious to confirm this ASAP, because I'm going to leave my ship with a mechanic for windshield replacement while I'm out of town the next two weeks...

Re: Windshield Moulding

Tim, Bob, etal,

I was told that the long side (bottom part in the picture) is supposed to be folded back ABOUT 90 degrees so that it meets the top surface of the boot cowl at an almost perpendicular angle. I think this way it will help hold some of the weight of the windshield. The bottom of the windshield fits into the upper groove in the picture. Then the whole thing is completely covered by the aluminum strip that you see on the outside across the bottom of the windshield.

I have tried it on a boot cowl not intalled on the plane and the long edge of the gasket ends up becoming curved, sort of folded back on itself.

Re: Windshield Moulding

OK, I got my windshield moulding the other day and it's a beauty alright...very business-like heavy duty rubber, a quality piece. But wait, how does this thing go on? Long side in the front? Short side over the trim piece? Put the moulding onto the windshield and then jam the whole thing into the windshield mounting trim place? Or put the moulding into the trim place and then jam the windshield into the moulding? Or what?


What I'm working with here is a project windshield that 20 years ago was installed with nothing but generous amounts of silicone caulking, What a mess! I'd like to do it right this time. So, please, what's the right way to install the rubber windshield moulding ?

Re: Windshield Moulding

Thanks for the info Hank. Should be able to figure it out from here. Also I just purchased another 41 BC12 yesterday, just like the one i'm rebuilding, so that should help also. again Thank you, Cropduster

PS. My new one is flying, so i can have some fun while i'm rebuilding the project.

Re: Windshield Moulding

There is a metal piece that screws into the top of the fuselage at the aft edge of the windshield that holds the aft edge to the fuselage. There is also a formed metal cover down each A pillar (the piece of tube the door hinges to) that holds the back sides in place. Finally there is a wing to fuselage gap seal on both sides around the leading edge of the wing (the long cover that wraps from the trailing edge, around the leading edge and back to the trailing edge again also covers the edge of the windshield at the wing leading edge).
The seal you get from Forrest or Tom slips around the bottom of the windshield to seal the windshield to the boot cowl. There is a piece of sheet Aluminum (usually 3 pieces) that covers the rubber extrusion that is a BEAR to make for such a simple piece. I have pictures of each part (somewhere) or can take some new ones, but I always warn ahead of time, I am usually really SLOW.
My 45 uses the one-piece windshield and my A&P (yes, I finally gave up and decided to hire out some parts) will be out on the 41 this weekend. :yahoo:

Re: Windshield Moulding

Hank, I'm doing the one piece, and am also wondering what is to hold the windshield in. Clips,or trim piece, or whatever? Also talked to Forrest last saturday, and he said he has the rubber moulding and will send it to me, same as Tom for $35.00 Mark

Re: Windshield Moulding

Could someone post some pictures of how the windshield mounts with the rubber moulding? Are there some kind of clips that secure the windshield to the boot cowl? I have a 41 with a one piece windshield. Thanks
