Windshield installation

[Dan1940Chief]

So the LP Aero windshield arrived and we're ready to install.

But, I'm having a very hard time replicating the two bent and curved kerfed plywood strips that were drilled through and apparently held the upper part of the windshield into the wing root.

So -- what can I replace this with? Marine or standard playwood will not work -- kerf and steam and it will not bend without cracking.

Dan,
Try rolling the strip and boiling the roll for 15min or so. You will need to work fast to form the shape you need. Hold it in this shape until the wood drys, generally overnight. You can add some ammonia to the water if you really need to make a tight bend. It helps the wood fibers to relax more than water will.

Thanks! I'll try that!

Dan,
If the wood comes apart it's junk. I check all of my plywood by boiling it. I have had some aircraft grade plywood, what ever that is, fall to pieces.
You didn't mention in your earlier post but I assumed you are using 45 deg. plywood. Standard ply doesn't make good leading edges or wing skins.

Dan,
I wrote you on the other site. Here's that message:

Dan,
I think what you need are parts, 3-22 Block - Cabin Fairing Corner. You'll need a right and a left. I attached a photo of my top wood from when I did the '39 65-C. This part was first used on the K and continued on through the 65-C. But,this is what gives the rounded transition to the top of the windshield.

It says spruce, but a maple, birch or other wood will work just fine. If this is the part you need, it's kind of odd to visualize. So if this is it, let me know and I can talk you through the simple way of how to make it. It's got a bunch of odd angles that you just can't set up on the bandsaw. I lost sleep on this on!!! No need for you to go through that too.

I can directly send you the drawing and a few more pictures.

Let me know,
Craig

That is the part, but I don't think the dimensions will be right as the windshield is "non-standard."
I tried using a more flexible wood backing to the kerfed plywood. It's glued up and I'll try it tomorrow.

Thanks for the reply!
