As far as the factories doing this " think a moment " If this cost a dime (10 cents) to install in a key and there are 88 keys and they build 10.000 pianos that year ????? Money saved IS -- 100 % -- PROFIT. If a Co. does not make a profit it sends it's employees home cease to exist -----------------. Is there an amen ????????? Jack Wyatt Dallas It might cost 10 cents to install that screw in the key, but wouldn't the factory save money not having to pay a keylever an hour to level a set of keys using punchings, as opposed to taking 10 minutes to turn a screw? But I'll give you an Amen, anyway.

The adjustment screw was like a large grand drop screw and was located near and in front the center pin. The bottom rested on a strip of felt in front of the center rail felt running the full length of the rail. the bottom of the adjustment screw rested on this strip of felt I rebuilt a 1920's "Bowen - Henderson'' grand with such leveling system. Leveling the keys was a dream. I inspected the center pin holes in the keys and there were no excessive wear to be found. In appx. 1962 J. P. Seeburg blought the P A. Starck Co. They made Spinets and Consoles. These Pianos had a screw type leveling system also. This was located at the back and beneath the key. This was simply an inverted upright let-off rail and was adjusted with a standard let-off tool. The systems described above will be on display in our Museum soon with original parts.
