RE: Pinning CA Hinges ???
1st, if CA hinges are installed PROPERLY they work just as well as other type hinges and are as durable. The key to installing CA hinges properly to drill a small hole in the center of the slot for the hinge. This allows the CA to penetrate the hinge and wood properly.
What many people do to "pin" hinges is to insert the hinge in the slot, then put a toothpick through the wood, the hinge and out the other side (a pilot hole made with a large T pin usually works very well ), THEN apply the CA to the hinge. The CA bonds the hinge, toothpick and surrounding wood into one unit. The part of the toothpick sticking out is cut off flush after the CA has cured.
In case you are not sure, use ONLY THIN CA for CA hinges.
