Most of the clock is made from American walnut wood that I source from Ocooch Hardwoods. The wood comes planed and sanded and is excellent quality. I have found that walnut is both strong and stable and I have not had any issues with clock wheels warping over time. As in previous clocks, I plan to construct the torsional pendulum from a combination of walnut and hard maple to add to the visual appeal as it rotates. I use drill rod steel for the wheel (gear) arbors (shafts) and the pinion rods are made from brass rod. Below is a photo of the raw material for this clock.
I believe that I have everything that I need to complete the clocks, but only just, and if I make a mistake I could have a problem especially as sourcing some of the material could be difficult at present.
