I cut the motor meter/hood trim piece yesterday, but was too sleepy to post it by the time I finished (late last night). The process I would like to pursue for realizing all these little parts is pretty intense, but it will yield awesome results. After the plugs are detailed and finished, I want to make silicone rubber molds of them, then cast them in wax, for lost wax metal casting.
I still need to create the recess in the firewall that will let the back drop into place, and the motor meter to fit into the wings properly. I cut the motor meter section from modeling board, and the trim section from a piece of oak wood. I wanted the surface quality the modeling board provides for the motor meter and the toughness the oak provides for the long, thin, trim piece; so I can work on it and test fit as much as needed, without concern of breaking it. It was also good practice in machining wood for the steering wheel.
