Seek Gears for Thompson Player Piano
By John J. Breen

A number of years ago, I rebuilt the player piano that now sits in my
family room.  Everything works great, except for one significant
problem.  Sometime during the life of this machine, when the bellows
started getting a little tired, someone changed the take-up spool drive
gears to make it run faster.

Now that I have fixed all the leaks, I can only play rolls with the
adjustment lever set way down at the slow end.  The net result is that
I have virtually no tempo adjustment (and it encourages my children to
play rolls much faster than they should be played).  In addition,
because the gears were replaced with flat spur gears, there is no
lead-in when changing from reverse to forward, so the teeth tend to
bind up rather than mesh.

Does anyone out there have a proper set of gears they would be willing
to sell for the player mechanism that is in a Thompson (Chicago) piano?

Thank you

John J. Breen
