Not much occured in December as B had taken time off from the project.

Below are paper drawings and forms used to scribe the patterns on the brass plate.

These patterns are then cut from the brass plate.

The 200 lb billet of steel below is what most of the ferrous steel parts for the clock will be cut from. It has a composition that was chosen for its superior color when blued. Most of the steel used in the clock will have a heat-blued finish, (all wheel arbors excepted, these are made from stainless steel and will stay silver colored). The video below shows the cutting of this log. Funny how one would expect a horizontal band saw, but this old-fashioned looking machine does the job.
