I like this idea, I’ve seen it several times as well as 19th C grands where the una corda lever simply has to be dropped down to let the action come out.

The purpose of the block of wood as I mentioned is to provide a new contact point for the unacorda lever. The lever had to be moved because of the plungers and pneumatic actuators. If I'm correct, this block will be visible in a large cutout which may or may not be visible with the lyre attached. If you remove the lyre and find this large cutout, shine a flashlight up in there and you'll see this block attached with screws to the underside of the keyframe. That's what's preventing the action from coming out. I had a Knabe with a player that had this arrangement, as well as a Weber and another player that I recently serviced. The block looked identical in each case, and the same type of screws.
If it's not a player, see if you can remove the unacorda lever. That may be what's preventing the action from coming out. In any case, if the action seems to be moving out a little, but not all the way, I'm quite sure there's this block in there that you need to remove.

Would this piano be a former player? Was the trapwork modified at some point? Is there a slot or holes in the keybed where plungers were formerly installed? If so, you will need to remove the pedals/lyre. With a flashlight, look up into the action cavity and you'll find a block of wood with some screws holding it in place. Remove the screws and the wood block. Then the action will come out.

Don't hold your breath, I can't find any way to get this thing out. Can't find a screw anywhere on the side of the keyped. Screws have been replaced in the lyre, backing them out, hasn't helped. Anyone with an additional suggestion as welcome.

I'll take a look at that, I'll be there later this afternoon. Trying to figure this out. Got a couple of great suggestions from this forum.

Is it possible that some piano mover put the wrong screws (longer) in the side legs and screwed the keyframe to the keybed? I have seen this several times over the years.

Often there is an oversized lyre screw replacement that penetrates the action. If you can swivel or pivot the action around a short arc you might even figure out which screw is the culpret.
Usually the screw only protrudes a short distance into the action and sawing off the tip is enough to get back to functioning.

I have a customer with a 19th century Knabe grand. I need to remove the action and cannot find the screw or device keeping the action from releasing and sliding out. Anybody experienced this on old Kenabe's?
