Thanks for the comments. I did some design work before attempting to build the hinge. One of the things I took into consideration was cracking at the hinge bracket on the hood. You don't see it but the brackets on the hood are of significant size. This is intended to distribute the stress over a larger area. I also rounded all sharp corners in order to reduce the stress raisers which propogate cracking. Finally, after bonding, I take fibreglass cloth and lay it over the entire bracket and the hood around the bracket. Then epoxy glass it. If you do not fill the bottom of the hood, you will not get cracking. If you do, with the key design implementations identified above, cosmetic cracking is highly unlikely. I could have made a steel piece across the front, but purposely did not in order to eliminate possible distortion which really can screw up the alignement of your hood with the body at the front.
I've seen a lot of slick hinges on cars. Just my humble opionion though is that I like the simpler look and operation. Hence the simple yet effective "hoop" design, and elimination of multiple linkage systems. You can't in my mind have a much easier method of installation and alignment them the method I'm using. I'm a proponent of KISS.
If anyone has any other questions, please feel free to ask.
