    Anyone have any brilliant ideas on how to rig the pedals so that the sustain pedal can be operated with the left foot without reaching across to the right pedal?  Have a customer with a bad right leg.  Steinway

    You could sacrifice the shift pedal and move the damper pedal trap work over, drill a new hole for the damper tray push rod.

    Now that's an interesting puzzle... 

    I'm picturing a tube that slips over the rod with a plate attached to the top, probably wielded on, that stretches to the other side and an extra angled brace between the tube and plate so it doesn't bend when pushed. I'm assuming they'd be sacrificing the other two pedals for this. Whaddya think?

    Brian Alexander made a system for Chick Corea to do exactly this and I installed it on a CFX we had at the Arsht Center back in February. It worked superbly. You should reach out to him  brianslostrings@sbcglobal.net or 805-226-2272

    Make a rather long lever that goes out at a diagonal to the left. The left end of the lever rests on the floor, the right end is attached to the damper pedal. Might be possible to play the damper with the left heel and the una corda with the toe. This could be portable, able to be attached to other pianos,

    More extreme: Remove the lyre and make a long trap lever that can be played with the knee, a la fortepianos.

    David,

    You already have the best answers about switching the sustain pedal, but I encountered a nightmare situation with clients arriving from the airport in 1 hour.

    The pedal lever broke a second time after welding. I've attached a photo (that doesn't include the repair. I'll have to get a photo next time I visit). The only thing I could think of - on the spot - was to take the sustain pedal off line and switch the damper pedal rod to the soft pedal position.

    I asked the young grade 10 level player if he could use it with his left foot until I had time to repair it.

    He said it worked great!

    I can always sense a problem with the sustain pedal nylon inserts/pedal lever weld when the damper rod starts lifting at a slight angle and not vertically. BTW, nylon pedal bracket inserts are no longer available as far as I know.

    Paul.

    This topic interests me greatly!

    I had a customer whose right leg could not operate the damper pedal. She bought a Bosendorfer concert grand and they made a special four pedal lyre. The far left fourth pedal was connected by metal braces that connected it and the right pedal together. So both pedals worked in "unison". The connectors were machined from brass and were a very elongated U-shaped with the U allowing the connectors to pass around the other rods.

    But, I have long thought the standard pedal arrangement is faulty. The shift pedal must pass around the other two pedals and since the shift must be towards the treble direction to avoid allowing the action to bounce on the return spring during shipping, one can't just shift the action to the left. (Some very old Steinway grands did shift to the left).

    With the right pedal as shift, the point of engagement with the keyframe would be placed very close to the same point the return spring operates which would reduce the tendency to "skew" the action which wears the action guides. Plus having the damper pedal on the left would position the pitman more towards the center of gravity of the damper underlever system.

    The times I played my customers Bose with the modified pedal and used my left foot for damping were uneventful. I adjusted in less than a couple of minutes. My wife thinks this is nuts but she never tried the Bose.

    Since he probably won't use the middle pedal, remove it, and then switch the right and left pedal.  This way the horn of the sustain pedal will be closer to the middle of the lyre.  He could then also use the left pedal when he wants to use it.

    Drum set players who use two kick drums typically have their right foot on their primary kick drum pedal at all times, and their left foot on either their hi-hat pedal or the the pedal for the second kick drum. The second kick drum pedal is next to the hi-hat pedal because it has to be played by the left foot, and that is where it fits for that purpose. It is attached to it's beater by a cable. This arrangement could be adapted to be placed to the left of the una cord pedal, yet activate the sustain pedal via cable. If the adaptation did not involve drilling any holes into parts of the piano, it could readily travel from one piano to another (at least, of the same make).

    Sounds like you have a promising lead making something like what was done for Chuck Corea. n case that is too hard to do perhaps you could get one of those pedal booster boxes used for children and jerry rig it so the left pedal will drive the rod on the sustain pedal . 

    I have a client here who uses a wheelchair and has no use of her legs. I researched and designed a plan to have the pedals powered by solenoids and a puff or a head switch but she decided to just play without any pedal function. There would have been no lyre and pedals would have worked using solenoids from player pianos.
