Aluminum Key Clamps
Modeled after the original Spurlock aluminum clamps, these are a collaboration between Supply88 and Erwin's Pianoforte Supply.
This pair of clamps allows an entire set of keys to be clamped together (in two sections) to simplify re-bushing and other repairs. Each set of clamps has a nylon strap handle. The clamping surfaces are lined with neoprene rubber, and each set has threaded rods that pivot for easy clamping and removal. A slight bend in the top bar provides even clamping force on all keys (the bar flattens out during clamping).
These clamps are made from raw 1" square aluminum extrusions (not fine-polished or anodized), so there will be some minor surface imperfections from the original aluminum extrusion process.
