Hi all,  Let me start by saying I am completely new to the world of
pianolas so apologies if I am asking something that is considered
obvious or rudimentary.

I have recently taken possession of a 'Holland' piano, which (from
what I have read) has a Standard player action.  The tubing from the
tracker bar goes into the back of a piece of wood that runs the length
of the piano and sits on top of the stack.  The piece of wood then has
holes at the front (underside) where it meets the stack.  I am not sure
if this is a typical arrangement but I haven't been able to find any
pictures which show this type of setup.

I have a problem with ciphering of a few keys, and when I inspected
where the tubing meets the wood I have found two problems:

1. The material used to seal the lead tubing to the wood (shellac,
I assume) has cracked.

2. The wood is splitting lengthways, making a crack that is joining
the holes the tubes are going into.

Given the size of the crack I am surprised this is not more of a major
problem, but obviously the shellac is still sealing for the most part
and only affecting a few keys.  However, given the cracks in the
shellac I assume this will soon become a problem.

Is it possible to re-seal this area by using a heat gun to melt the
shellac?  If not, how should I attempt a repair?

Regarding the crack in the wood, any thoughts on how I would go about
fixing this?  Is it a common enough part that I could purchase a
replacement.

Thanks,
Rob Mashiah
