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'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.
Do I see broken tool there? ;)
The tool looks like a boring bar not a drill.

I mean the one seven or eight holes CCW in same row, or did he just marked first one?
It looks like he's currently reaming the holes, they were drilled in a previous step. So mark where you start so you don't redo the same holes all day.
Well,I looked but didn't turn up one I expected to head the list. It's about 1955 from K&T itself, about 20 minutes. It's the only one that puts it through its paces, albeit a demo.Quote:
