Here is a series of photos showing how I approached building the windlass. I took a piece of boxwood 3/8" square and cut it into an octagon on my table saw. The piece was cut to 3" in length (about 9'8" in scale). I measured in about an 1-1/8" from each end, and tapered the boxwood by sanding, maintaining the octagon profile. I measure and marked the rabbets for the supports and the center gear. They are all about 1/16' deep. Next, I cut the gear in the center to shape, using a #10 X-Acto blade. Last, I laid out where the holes for the lever rods would go and drilled 1/16" pilot holes at each location. I then took a nail that I had previously filed to a square point and tapped it into each hole, converting the round drill holes into square holes. In the photo, the holes on the left side of the windlass are still round. The windlass supports are rosewood with double timberheads cut into the top of each side.
