Nice littlescoop for loading the trams. How was it powered?
I didn't see it in a quick scan of the description. Patents sure where sorter back then, mine is a LOT longer after the lawyer spiced it up.Quote:

A man-sized machine and a man-sized job are effectively handled by 21-year-old Virginia Grochowski of Milwaukee, Wisconsin. Employed by a Midwest supercharger plant, this former hosiery mill worker operates these giant drill presses as expertly as any man. Allis Chalmers Manufacture Company. October 1942.

Knew that machine tool instantly. NATCO Multi-Spindle Drill Press, common to run 21 spindles. Close spacing would use RH and LH bits for a compact gear train. The head descends to pre-set stops, varied depths accomplished via individual toolholders. Despite ungainly size, an efficient production machine from Indiana.
And believe it or not still sought after.
I appreciate you input about that machine. Makes some things click in my brain.
I appreciate that. I don't get too much toolwork in these days, so compensation is in form of historical and topical comments.Quote:

They and others built a tremendous variety based on box column versus round. You've never drilled until you lay hands on such a machine. My favorite are Cleereman, and Fosdick.
LOL Your comments are always great
