Wooden Gear Clock Kits and Plans
By James Grahame
Jeff Schierenbeck makes two $149 wooden gear clock kits (this is the Ascent). The punch out parts are made entirely from 5-ply Baltic Birch plywood that is void-free to ensure proper mass and strength. The mechanism accuracy varies depending upon humidity and temperature, but they're typically accurate to within a minute a day.
I suspect that getting one of these to work just-so is a fiddly business, but the manufacturer claims you can complete the kit in within a day. The components are pre-cut, but you'll have to stain them to taste and you'll need to have a screwdriver, hammer, wood glue, and sandpaper on hand. Methinks this is a great opportunity to learn about classical clockmaking from the inside out.
