Wooden Gear Clock

Step 7 Gear Placement

I drew rough gears in Blender with the Outer Diameter and Pitch Diameter to figure out placement in the frame. This told me if I will have interference between a gear and an axle, and give me a rough idea where my axles will be placed. After creating a 'template' on where to drill the holes, I drilled the first one starting with the Escapement Axle. Once that was drilled, I slid the gear on an axle, placed it in the hole, placed the mating gear on an axle, and held it in the approximate location. I then modified the placement of the next gear, marked it, and drilled the hole. Then I would re-check the fit with both gears on an axle fit in the hole. If it fit, I was on to do this again with the next gear. This continued until all the holes were cut, and the gears fit.

Three axles will go all the way through the frame, and three axles will have blind holes. I now have one side of the frame drilled, but I need a matching frame. In order to get a mirror image of the holes, I cut a half inch length of 1/2" dowel to place in each hole. I drove a brad nail into the center of each piece of dowel and cliped off the end of the nail with a pair of snippers. I placed the mating board on top of the nails and pressed firmly. This left an indentation where each of the centers of the holes should be drilled.

After the holes were drilled, it was time to assemble the clock.
