Richard:

1. I was of the mind to avoid aluminum rivets because of strength and the supposed galvanic issues
with carbon.

2.  Here's what I did:
2a. Drilled 1/4" (I think) holes all the way down the hinge
2b. Surface prepped the carbon area and hinge half
2c. Painted on a VERY thin flox mixture and then set the hinge down.  
2d. Painted on a VERY thin flox mixture on top of the hinge followed by
2e. Painted on a thick flox mixture about 0.050 I'd guess

3. I'm not sure what adding glass on top of the hinge would add structurally because the key
securing means are the "flox rivets".  After the hinge, the cloth would immediately encounter a 90
curve so that no effective tensile strength would be obtained.  If anyone knows better, I'm all
ears!
