I haven't rebuilt a Gulbransen Player so maybe on of the tech's could
help out this chap.  Please send direct but also send a copy to the
Digest as I wouldn't mind knowing the answer myself.

 Subject: Gulbransen Valves

This is my second visit to your site.  Thanks for maintaining it.

Here's a question:   I am rebuilding a Gulbransen Player Piano.  All is
proceeding smoothly.  As Reblitz and Player Piano Supply have suggested,
I have sawn the trunk into three sections.  I have recovered the
pneumatics and installed new pouches and valve discs with new leather
facings.  Now, here's the point:

I am a little concerned with the amount of valve travel that is optimum.
I have a good "dish" on the pouches and the valves all move up and down
quite nicely.  However I am wondering if I really need the  paper rings
that some sources suggest that I use under the wooden valve rings on the
deck surface.  How much travel is appropriate?  There is a definite
"thunk" as the lower valve facing hits the brass seat, and at least
3/32-inch travel to the point at which the wooden ring would be after
gluing without the blotter paper ring.  If the ring is necessary, why
wouldn't Durrell Armstrong at PPS Co. send it in the rebuild kit?
Any thoughts?  Thanks,
