2015-11-29 (Su) Desktop Chording Keyboard

Cut lines were followed by using a table saw at a hack space. A fence and sled ensured a straight cut. The sawed edges were rough and a belt sander was used to smooth the faces. The edges were rounded as well but only slightly so the sharp corners would not be uncomfortable or easily damaged. The marked holes were drilled according to their desired sizes. Holes meant to pass wires were drilled to 3/8" (10mm) so the connectors could pass through easily. Keypad mounting holes were drilled to 1/4" (7mm) but the holes drilled in the keypads were merely pilot holes to catch a screw.

Once a pair of pilot holes were drilled into a keypad mounting block the block was secured with long screws while the other keypad mounting block was unfastened. From here the second block was accurately aligned before it was drilled. This procedure ensured the keypads would be mounted squarely.

All keys mounted

A layer of stain mixed with polyurethane was applied. The color was intentionally much different than the keypads to give it contrast. The base was allowed to dry overnight. Once sanded smooth it will have the keypads wired then attached. Accent pieces will also be attached at the corners to prevent damage and add to the look.
