[CAUT] Removing jack stop rail

[Mark Cramer]

Hi Bill, at one time we did a lot of brass-rail conversions on vertical
actions.  I've pasted the following from my tear-down notes. Hope it helps.

 

Best regards,

*	Remove the jack-stop rails:

 

*	Measure and record the average spacing (inside measurement from wood
to wood) between jack-stop and main action rail: _______________________mm.

 

*	Label rails bass, tenor and treble.

 

Note:    Loosen the positioning screws (use regulating tool) each a bit at a
time to prevent bending or breaking rails, loosen screws only to the point
of detaching the rail, do not remove screws from the rail.

Subject: [CAUT] Removing jack stop rail

 

I've been servicing pianos over a period of 50+ years but have never had to
remove a jack stop rail until now.  Are the long, thin mounting screws
threaded one direction the whole length?  Or are they as I seem to recall,
like a turnbuckle, left thread on one end, right on the other?

 

One of the institutions I service has a Knight studio (1963 vintage) that,
instead of felt on the jack stop rail had something akin to sponge rubber,
that has disintegrated making a mess and causing clicks as the jacks hit the
rail.  I assume I can get the rail out but want to be sure I can get it back
in properly regulated after cleaning and gluing felt on.

 

Any suggestions will be appreciated.
