Steinway D #411101 Bridges glued to board

My sound board press is unique as it also doubles as a bridge press. After appling glue, I fasten the bridge to the board with temperary screws through the ribs where dowels will be installed later. The the board and bridges are placed in the press to add additional clamping pressure along the entire plane of the bridge.

After the glue has cured, the screws are removed from the holes in the ribs, and wooded dowels are installed through the ribs and into the bridge.
