Last year I rebuilt a 1911 65/88 note Lindeman player piano and have
been having trouble with it ever since.  I got it in completely original
condition and replaced everything.  I've re-leathered valves, re-covered
pneumatics..the works.  I really thought that this would be my masterpiece
because I took my time with it AND it's a fantastic piano to begin with.  I
got it playing nicely, but not nice enough.  It's leaking air like a sieve
and I couldn't find out where if my life depended on it.  It has new gaskets
and all are nice and tight with no stripped screws so I don't see how it can
be leaking from a seam.  The travel is adjusted to its' correct 1/16 travel,
and I've never seen a more perfect set of pneumatics.  Despite all of this I
have to pump unusually fast to get repetitive notes to play as they should.
It's quite aggravating, especially in dry weather.  Then I have to work my
legs to the hilt !! Can someone out there please help ? Is this a serious
problem, or is it the way it was made.  I know of a few pianos that simply
weren't air-tight even when they were new. I hope I don't own one of them.
