Okay, here goes! I have read many articles about all the various ways
in which to rebuild the glued Gulbransen stacks, including laying it on
a slightly convex concrete floor and whacking it to break it apart,
deep-freezing it to weaken the glue joints and then whacking it, and
the most popular: sawing it precisely in the right spot which varies a
little depending on which article you read, then gasket the whole thing
(with a gasket of your own creation) to compensate for the saw cut and
bolting it back together. Each author offers personal testimony about
the success of their personal favorite procedures and I appreciate the
information more than they can know.
I have also recently read about a procedure to disassemble pneumatics
by heating them in a microwave to soften the old hide glue by heating
it. HHHuuummmmm!
If you can soften old hide glue by heating it -- and from what I have
read so far it seems to be one of the wonderful characteristics of the
stuff -- why couldn't I heat up the stack in a very large oven and
simply tap it apart? It seems to me a very logical approach to the
restoration. Has anybody ever tried this or had similar experiences?
I am anxious to hear from anyone who has worked with old hide glue.
Sincerely,
Doug Anderson
