I spent most of the winter and early spring working on an earlier-deadline project, so it's only been in the last couple of weeks I've gotten back to this. The main progress was:
Right now it's in three separate pieces:
The plan is to cast each of these separately in fiberglass, then glue together with bondo, bolts, etc. I might separate the cyclotron from the synchronous generator and cast them individually. It'll be more work, but it'll let me adjust the rotation of the cyclotron to be level with the bumper. I'm a little worried about that detail.
