[CAUT] steinway reproducer

[David Ilvedson]

Jon,

I do not work on players so I don't have vacuum gauge.   The pianist is a teacher at my school who is complaining about the mushy feel he attributes to the longer keys of the piano.   I noticed friction at the knuckle I had wanted to deal with...that is the only reason I wanted to pull the action.

I may be removing the action from a rebuilt Steinway reproducer tomorrow.   It has been awhile since I did this.   Any tips on how to go about it?  



It'll take initially 45+ minutes to get the action out. About the same to get it back together.





You'll get faster with practice.  :-(





Have screw containers handy to place each set of screws into. The controls do not have to be removed but it is better to unscrew their support brackets and let the levers drop below the keybed surface. otherwise you have to slide/lift the action over them. Put all the bracket screws into their own container. Control cover screws. Control panel cover screws.





Put all the union block screws under the keyframe (remove the lyre first) into their own container. You get the picture.





Same goes for the wind motor and spool box, etc. in front of the action.





For storage containers I use plastic milk bottles which have been cut down to 2 or 3 inches.

This will speed up the reassembly process.





If the hoses are not already indexed to their respective nipples, do so before you disconnect tubing.  The union at the bass side of the action can be particularly problematic.

Especially so depending on the quality of the rebuild. Hopefully the union faces will have new suede surfaces and the screws aren't stripped.





But first and foremost, have the owner run the player through its range of expression

to verify all is functioning well, 88 note rolls too.  You don't want to hear, "It worked before you took it apart", even if that area of function was not associated with your work.

Do you have a vacuum gage to test intensity and a test roll? The test roll will have a chromatic repetition test. Always good to know before you dismantle.



Regards,
