While I am using a good grade of hot hide glue, it still gives off
an odor that is a bit smelly.  But on to the headache.  When I was
restoring the Weber grand I was under the piano removing the dried out
rubber tubing.  I kept getting headaches and irritated eyes and nose.

One morning the sun was shining at such an angle that it hit under the
piano as I worked.  As I snapped off the old tubing the sun revealed
a cloud of tiny glistening particles that drifted down.  Who knows what
compounds were in that old organic material.  To finish the job I wore
eye protection and a breathing mask which eliminated the bothersome
headaches.
