Weighing the Keyboard
The key leads are cut into ¼” [6.3mm] long pieces with a nipper from a roll of 1/4" [6.35mm] diameter lead wire (see Key Leads - Chapter 36, page3). Using a 1/4" [6.3mm] brad point drill bit, drill a hole in the side of the key at the position of your pencil mark(s). Drill only as deep as the length of your lead weight. Place a piece of lead into each hole and place the key, leads up, onto a flat surface or an anvil. Tap the lead three or four times with a hammer and screwdriver blade. This expands the soft lead and wedges it into the hole.
