We at the Minnesota Transportation Museum just got a free surface grinder donated to us , unfortunately it came in a bunch of boxes. We have no idea what it should look like, so we don't know how to put it together.
It is from "Robot Machinery Co new York, no model number, can anybody shed any light on this piece of machinery, a picture from a manual perhaps.
Courtesy Google image search, though I can't get the page it finds that's supposed to have this image to load properly - any of those look like your parts? I can't quite see if it's really the right name on the machine.
