Flexible Hide Glue?
By Douglas K. Rhodes
Greetings:
Here's a skill-testing question for the rebuilders:
I'm presently working on a Seeburg nickelodeon. Several of the pneumatics, both large and small, are of the style whose ends are not cloth-hinged - they look more like a lop-sided box than a wedge. The boards do not meet at the narrow end. The cloth laps across the narrow end, requiring a good flexible lap joint. (The problem is similar to that of gluing up the pouch leather to the cloth on the opposed pneumatics of the Duo-Art wind motor.) These "box" pneumatics all function with the narrow ends held almost shut by metal hinging mechanisms, but open enough to allow the extra fabric (folded inward) to take the stress of repeated cycles. I guess the theory was that the metal hinging would help the pneumatic to last longer than a standard cloth-hinged type, given the severe duty cycles that nickelodeon parts must endure.
My question:
What kind of glue is best suited for these lap joints? Straight hot ghide glue seems too brittle. I have never had very good luck with rubber cement. (The stuff goes gummy, or won't dry, etc.) I _have_ successfully used a PVC-E glue for this kind of joint, where I will first allow the glue to dry on the separate surfaces, than iron or otherwise heat them to stick together. But this is no good on pouch leather. 90% of my gluing in the shop is done with hot hide glue. Is there something I can add to the hide glue to increase its flexibility, making it more suitable for this type of "working" lap joint?
