Machining a space shuttle main injector in 1977 - photo

How about the tooling behind the workpiece?
Now THAT's a spindle indexer!
Even if it's only a manifold, didn't originate without indexing...still only 1977.

I'd be so worried about making a mistake on that one!!! especially as you get closer and closer to the end. Respect for that guy!

I too, affixed a rotary table to extend range in replicating iron speed change pivots of Bridgeport type mill. When imported versions first appeared, their interpretation was a poor casting. Even C1018 8" x 1.5" improved that situation; that I made near 30 years ago still operative 100%.

I'd love to see a video/movie of it in action!

I like the C clamp in the bottom of the picture surely a precision application.

I think the C-clamp (D-clamp when it's closed???) is holding a shield to keep chips out of the works.
