I've done an experiment with the fish glue.
I had a piece of scrap cherry and pieces of mahogany binding. I spread fish glue, CA glue, Titebond, and Duco, onto 4 pieces of left over mahogany binding. I allowed them to dry completely.
I spread fish glue on top of each of the glues, and put them onto the cherry yesterday afternoon. I allowed them more than 24 hours to cure. Today, I attempted to remove the mahogany binding from the cherry. This is the result:
1. Fish glue to fish glue: The fish glue created a very strong bond. I would have broken the wood if I'd tried to separate it. So, fresh fish glue will bind to dried fish glue.
2. Fish glue to CA glue: The fish glue adhered to the CA glue, but I was able to break the bond easily. Don't use this combination.
3. Fish glue to Titebond: The fish glue created a bond with the Titebond, however I was able to break it with moderate pressure.
4. Fish glue to Duco: The fish glue created a strong bond to the Duco. I was able to break the mahogany away from the cherry, but it took quite a bit of pulling to do it.
