Hi,  I have a 1914 Autopiano.  It still has the original lead tubing
on the tracker bar to the stack.  It does still play fine actually, so
I don't have to replace it, but I would still like to replace it with
new tubing.  Can anyone help me with any tips and ideas on how to safely
remove this without causing damage to the tracker bar nipples and the
stack?

I have never seen it before with the cloth covering.  I was told they
used this to keep it from oxidizing.  Also, it's not soft, really like
lead is, but almost looks like brass to me; it's very hard, like brass.
Did they use brass tubing on these?

Any help you have or pictures of stacks you did removing this tubing
or diagrams would be great.  Also thanks for the replies I got from
people with help on re-doing the Aeolian wind motor, I sure appreciate
it, as I'm new to this hobby. :)
