Firewall

On the back of the firewall are three wooden slats. They are the same ones used in the fuel tank cradle and they serve the same function. Plus, they give some stiffness to the upper part of the firewall itself.



Here are the slats in place. They will get a felt strip attached later.



The firewall was trimmed and the upper flange riveted last night.



The slats on the fuel tank cradle are attached to the steel straps by machine screws and nuts. Unfortunately, these screws stick out far enough to make contact with the firewall. I don't know why, but that's the way Curtiss designed it. So, we did the same thing.

Bumps had to be made to accommodate the screws. There may be some more sophisticated way to make them, but I used a ball peen hammer as the form. Just strike it with another metal hammer to stretch the metal.



Just work it slowly and angle the ball peen end to get the desired radius.



It works really well. It seems like a few whacks and the bump would be formed, but it takes longer than that. This is galvanized steel, remember?



The bottom lip of the firewall was bent to shape, too.



Here's a lousy picture of it. Time to change batteries in my camera.



Pretty productive day!

Enjoy

Brian
