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, Mark Cramer Brandon University * 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. _____ From: caut-bounces at ptg.org [mailto:caut-bounces at ptg.org] On Behalf Of maxpiano Sent: November 6, 2008 7:29 PM To: caut at ptg.org 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.
