It's set up on a knife edge arrangement for static balance, just like grinding wheels. The center to right takes one end with prop laid down, guarantee that shroud to left houses a profiling template and sander, judging by tool marks.

I started to teach Precision Machining at the High School level in 2013, but some days - I swear it was 1913! We do have dial calipers now, but I'd trade 3 of our import lathes for that one in the picture. It's probably still making chips somewhere (or at least capable of doing so).

I believe #2798 shows the foundry molding floor with a lot of what appear to be core prints placed in the mold. The pattern has already been removed.
