Just a note on hide glue in general. Jim Skaggs, a factory rep of Aeolian Co. , years ago, said they did tests with hide glue and found it to be an extremely strong glue, but only when newly made up. The second day of pot life the glue was only 60% as strong, and by the 3rd or 4th day it was all the way down to 25-30% as strong as new. The heat of the pot degrades the glue into smaller chain molecules, or whatever. You add to that the fact that the glue is a protein in water, and is immediately attacked by bacteria when cool enough. Think about letting a steak sit on the counter overnight, and then the second day, and then the third. The bacterial load could get immense. That is why OSHA theoretically made them add preservative chemicals, which are biologically poisonous. For most player work, weak glue for pneumatics and sealing is just fine. But for permanent wood to wood casework and veneering, Aeolian made if fresh daily. All those who want to taste their old glue now, raise your tongues. Bill Simon Phoenix
