wooden

Ron, who is a craftsman of wooden machines, has figured out that, to best withstand environmental changes, the grain in a wooden clock wheel should run in a circle around the circumference, and in radial “spokes” in the middle.  Real trees don’t grow that way, of course, so if you’re really serious about cutting wooden gears that will weather the seasons well, you need to cut them from blanks made up from a bunch of smaller pieces of wood arranged and glued so that the grain pattern, on the whole, is correct.
