    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!

    Toolmaker51 says "This remains the single most intriguing machine tool; in operation and ability to contour with minimal setup."
    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 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.
