I'm hoping somebody may have previously solved this problem.
My 'classic' -6A kit has a firewall with the main part being stainless and the curved out side cheeks are aluminum. I fluted the cheek flanges in the normal way to eliminate the manufacturing bow in the flat part of the stamped parts. The attached pic shows the flutes on one side, though the photo is rotated 90* for some reason that eludes me.
Now the piano hinge for the cowl needs to be riveted on the inside of the flange, but there is a problem because the hinge won't sit flush against the flange because of the flutes.
I guess I could cut small .032 shims to go in between every flute, or use liquid shim (epoxy with micro) to make a flat surface for attaching the piano hinge. Is this viable, or did you solve the problem another way?
Thanks
Paul.
