Keyboard hold-downs

As the keyboard was designed to transpose, the key frame must stop slightly short of the lower bellyrail to allow side-to-side motion. This means there's a bit of front-to-back slop when the keyboard is in place. In addition, the light weight of the keyboard means it might not stay still if the instrument is ever moved, which often involves flipping it onto its spine.

I made two hold-downs that attach to the baseboard inside the keywell, just behind the front rail of the key frame where the head stop cloth is stapled down. Here's one of them:


It's basically a scrap block and a mirror support clip used to attach mirror glass to walls. When the keyboard is in place, the mirror clip ensures the key frame is kept fully forward. It overlaps the rear edge of the front rail, holding the keyboard down:


The block can pivot out of the way if the rear screw is loosened. This releases the keyboard and allows it to be removed.
