My LHS gave me a sample of a new CA glue from Bob Smith Industries that is made for CA hinges. Its called Insta-Flex and it is a thin CA that remains flexible when cured. It is being marketed for use with CA hinges. I have tried it on several sample pieces and I think it will be a big seller. The bond is extremely strong and because it stays flexible I think the hinge will perform better and should be less likely to fail. The test pieces I have made up are very smooth in motion with no popping or cracking when the hinge is moved, even to extreme throws similar to 3-D airplanes. (I used SIG easy hinges on my test pieces) The new glue is being produced in bottles with a Teal colored label and cap.
