Napier's Bones: Quickly Multiply, Wooden Style

Step 8 Glue Fixed Bones

The piece with just horizontal lines and one side of numbers is the fixed vertical piece. Using wood glue, glue it down on the left side of the hardboard. The bottom of the piece should be flush with the bottom of the hardboard, but there should be space at the top. Clamp and let sit according to directions on the glue.

Glue the small piece perpendicular to the vertical fixed piece and flush with the bottom of the hardboard. Follow directions again!
