Hi Hal,
The outermost hole in my blade carrier is tapped 2-56 (threads hardened with CA) for a nylon screw. I have placed a 1/4" dowel "hardpoint" in the blade that is drilled for the screw. I put the 2-56 nylon screws through the hardpoint and into the hub, leaving about 1/4" sticking out the bottom. When the inevitable occurs, the screws are cut cleanly allowing the blades to fold. I grab the remaining little stubs with pliers and screw them out the bottom. Then I replace the screws and voila, ready to go again!
Whew, much easier to do than to describe in writing.
ps: You are my hero!

You're the man that got me started on airfoiled stabs many years ago.
