Adding Key Coverings - Part 3

The boxwood key coverings were flipped over and glued onto the key levers, again with hide glue. 

The decorative lines on the keys were carefully scored using a straightedge clamped to the keys. The X-Acto knife made straight, but very thin lines as before. This time, the lines were widened slightly using the tip of a thin screw driver blade instead of the Japanese saw. The screw driver blade acted somewhat like a mid-19th century American farm plow, which tracked the X-Acto lines easily and widened the lines as desired without slipping.
