[pianotech] Speaking of players .......

[Duaine Hechler]

it takes a lot of time, SKILL and PATIENCE to rebuild one of these.

Sure, regular (and players) have to have the standard regulation, etc
BUT players also have to be AIRTIGHT as much as possible.

This takes EXTRA SKILL and PATIENCE

As in this picture, like in the regular piano action, there are - 88 -
of these little valves that have to rebuilt - along with every thing else.

Plus, when the valve is in place, there has to be a specific clearance
of play - which is - 0.035"

Times 88

So let's break this down, from left to right:

1) a leather punching - with the proper thickness, outside diameter, and
inside diameter.
2) a felt punching - with the proper thickness, outside diameter, and
inside diameter.
3) a fibre disk - usually - reusable
4) a leather washer - tight enough on the valve stem to be used as a
"nut" to aid in regulation of valve height
5) a valve stem - usually - reusable
6) a small leather punching - used as a floating washer
7) a metal backing plate - usually - reusable
8) a leather punching - with the proper thickness, outside diameter, and
inside diameter.
9) a metal backing plate - usually - reusable
10) a small leather punching - used as a floating washer
11) a "force fit" collar - NOT reusable - and - getting hard to find
12) a "push up" disk for which the leather pouch pops up to activate the
valve
