Thanks to all who responded to my question.  I found that some people
didn't read the question too well -- I was removing glue from plastic
pneumatics and not wood.  But I thank you all for the suggestions that
were sent to me.  I will take them all to heart and if I ever get
a stack that is wood I will try those suggestions sent to me.

As for the player stack with the plastic pneumatics, I used rubbing
alcohol and they cleaned up really nice!  It's all together again and
works great!  Take care, everyone!

Sincerely, Jeff Bridges
