    Greetings, I have a client with Ritmuller upright with keys sticking because of the keyslip. I cannot figure out how to remove the keyslip so it can be shimmed. I almost seems to be glued in. I'm not at the piano now but i'm wondering if there might be a bolt in the keyframe that can be adjusted to push out the keyslip a bit.

    Thanks ahead of time for any suggestions.

    Some uprights have keyslip machine screwed through a tubular aluminum frame: either under keybed with screw heads facing strings or from inside keyframe and only visible when keys are removed.
    At times the keyslip is attached to cheekblocks and upstop rail as a single unit.

    Thanks for your reply Horace,

    According to Mark Wisner at Ritmuller USA the keyslip is in fact glued in. The solution is to install (wedge in) a shim between the keyframe and keyslip thereby bowing the keyslip slightly. All I need is about 1/32 of an inch, tops. There is about a 1/4 inch gap between the keyslip and keyframe. So I'm brain storming possible items the could be used as a wedge. My first choice is a short thin dowel laid horizontally and hammered in. I'm also thinking a tuning pin might work. Will know more when I revisit the piano tomorrow. This particular piano design is rather disappointing. Why? I ask, Why?

    a few pictures may be helpful to post. i would be very careful about hammering something in the size of a dowel or tuning pin and I would try doing it at the ends of the slip near the keyblocks. Too thick a material may end cracking the key slip.there are some clear shims used to level table legs and appliances that have a taper to them. you may only need a half inch to an inch of shim to bow out the keyslip. I used some small pieces of aluminum strip that was very thin and flexible folded over itself . It was a perfect solution on a Kawai that had key fronts hanging up. I got the material at Lowes Home Improvement in the nuts/bolts/hardware section. It was in a cabinet with long vertical drawers that had specialty hardware. the drawer was labelled craft parts, hobby parts, science fair parts

    Why? Right now I'm wondering how, if the keyslip is glued in, is it warping? Just glued to the end-blocks? Does the bottom of the keyslip rest on the keybed or does it butt up against the front of the bed? If it butts up against the keybed, maybe you could shim it from underneath.

    You might want to bring some slips of wood around the thickness of that 1/4" gap and then fine tune with front rail punchings or an ivory tail. As the keyframe and slip aren't going anywhere it should be more or less permanent even without glue.

    Perhaps the keyslip isn't the culprit. If it's glued in place then it is a constant that other parts adjust in relation to. Is it binding in the middle or to one side or the other? How many notes bind? I'd verify that it's bowed at least by line of sight first or measure it against the keyframe and balance rail as well.

    Or you could loosen all the screws holding down the keyframe and nudge it back 1/32nd". Or just the balance rail. Baldwin has a trick balance rail for adjusting key height, maybe this one can adjust fore and aft. 1/32" isn't much.

    When I ran into this I got a 1/4" bolt and nut 1/2" long. Chiseled out a space where the sticking was worst. Put the nut on the bolt and gradually backed it off until there was clearance.

    Thanks for all the suggestions....all of which would work. Here's what I finally did. Flexing the keyslip enough to insert the shim was next to impossible...at least without a crowbar. Instead, I used a narrow tuning pin punch to drive in a nylon spacer shim.  I inserted a shim about a third of the way in from both ends of the keyboard.

    Thanks again for all the responses..

    Hello Randy,
    Last week, I serviced an off brand piano and there were two captains at 1/3 and 2/3 positioned in the key frame to keep the keyslip from bending inwards.
    Not sure how to remove the key slip though...
