Almost done with the shell! I have a little clean up work to do on the back of each half, around the sockets, but it's pretty much there. I ran it through the programming software and the machine times are reasonable with a 0.125" ball end mill, so cutting the plugs will work as intended. The funny thing about this is it's probably the only part on the entire car that has no functional aspect, but I have an incredible amount of time invested in it, with a longgg way to go. Along with what's left of the T-bucket body, it's the signature piece that identifies the car (also identifying the specific vintage), so it's critical to helping all those other functional parts come together aesthetically, as a sum, a whole, a car...
I decided on four, large, heavily stylized,bolt bosses to clamp it together; and had a little fun with the upper mesh bars, bending them around the bosses. Those will probably have to be printed, as they have too many angles to machine (possible, but not practical). If the bolt bosses look huge to you, remember how tiny the whole thing is, and the fact that it's between your knees and ankles on the car.
Today, I am cutting wood mock-ups of the front and back halves of the shell - without the sockets - to test it on the car, and develop the hard numbers for the wings and motor meter.
