Good Day to All,  Recently I told you of my pruchase of a Marshall &
Wendell Upright console player piano.  I have the piano part at least
functionally to the point of now turning my attention to the player
stack.  The tubing in the back is lead and is cracked in various places
and on various tubes (naturally!!).

My questions to the group are:  Is there any reason why I can not use
rubber tubing to replace the lead tubing?  I plan on replacing *all* the
lead tubing.  The Player Piano catalog has some really good tips on
tubing removal.   If I take their advice and go with the reducing nipples
(7/32" to 5/32") how do I seat the nipples?  Is hot glue appropriate or
necessary?  Will I still need to seal the top board that the tubing goes
into, or the tracker bar for that matter? If I do I assume I should use
thick shellac?

FYI for those following my saga.  The pneumatics on the stack are rotted
out in the corners, so I will be repairing them at a later date.  The
secondary pouches, and primary valves are good condition.  I will have
some work to do on the secondary vales. Once again age and poor care have
crippled what I am sure at some point was (and hopefully will be again!)
a fine piece of craftsmanship.  Thanks for all the help and advice.
