I kind of reluctantly entered my CAD workshop today, to resume work on the grille. The reluctance is because this is the kind of stuff I love doing, and hours, then days, have a way of disappearing while I'm in there. The ball-n-socket bar mounts are finished, and the bar cores can now be produced. I decided to machine them. When the ShopBot is working properly, I am able to get the accuracy I need and these will be cut from plastic, then laminated with carbon fiber, so I can keep the feed rates reasonable enough to not be on the machine forever.
The reason I am bouncing around so much is to get all the major parts sorted out and underway, so that as the car goes together there won't be anything that completely stops progress in its tracks. As I work on assembling the car, I am able to identify the needs for each area, step back and address them, then move forward a few more steps toward a roller. No matter how much planning you do, some things just can't be determined until the car becomes more of a tangible reality; like sitting in the driver's seat and thinking through actually driving a car that has never existed before. It's a really fun, rewarding, process.
Next up, the grille shell. That's where the time-space warp can occur. I'm tying a rope to my ankle; if you don't hear from me - pull...
I think the shell is also going to be cut in plastic, and then cast in aluminum, then plated. The smallest radiuses in the sockets will require an 1/8th" ball-end mill, which means it's going to take a while to cut, even in softer materials. If necessary, I'll split it into four sections (for each half, eight total) and glue them together. First I'll try separating the socket machining operations from the rest of the shell, and tricking the ShopBot into getting the job done quickly. Again, the point is to try to develop processes Columbus Idea Foundry members can use, with the available equipment; and help market its offerings and capabilities.
Holds nose, and jumps...
