  • 1.  Lyre work

    Posted 2 hours ago

    One of my church clients has a 1940's Kranich and Bach that had some work (new pinblock, strings, action repair) in the 80s-90s.  They did not rebuild the lyre, so the sustain pedal is really loose - so much so that the rod keep falling out.  I told them I would work on it and it has been decades since I worked on one(with my mentor) and I cannot remember what to do.  I tried researching this topic and am not coming up with much on here.  I am going to pick it up after church today.  What should I be looking out for when repairing and making the pedal more secure.  And should I also purchase some new pedal rods from Schaft?  Any ideas appreciated!

    When you say it’s loose. What does that mean? Is the pedal itself wobbling? Is the trap not holding the rod in place?

    The pedal has "side to side"  movement-a lot.  The rod is not attached to anything at the top.  The trap  has some old leather on the bottom and the rod just falls out

    Take the lyre box apart and check what and the pedal is attached and fix anything that is broken. Also replace all the leather and felts on the traps. You should’ve also checked springs inside the action cavity.

    I would first take the lyre apart noting and numbering pedal rods. Check bushings that support lyre rods.  Check pedal pins and pedals for looseness. Finally

    examine all glue joints and repair as necessary.  The rods can be polished and lacquered.  Refelt lyre as needed. It is surprising how many rebuilders neglect

    lyre, trapwork and damper work.  Charge accordingly and make sure after repairs that lyre fits flush to the underside of keybed (no daylight) and that the

    lyre support rods are tight.
