Hello,
I've now got three tables with these similar "machining" marks on the surface. Third time's the charm, so here I am. WOC is about one inch, on all three. Linear, in a single direction. No visible tooth marks.
Too wide of a cut for a shaper, no circular cutting marks from a mill, don't THINK you'd get that surface finish from a surface grinder...
Additionally, what is this largest table that you see below? It has substantial webbing on the opposite side of the casting. All five sides appear to have been surfaced. Is it a surface plate for inspection/gaging? Just a table? Probably 600-800lbs, I found only a few markings.
Let's discuss. I'm very curious now, and I'm certain someone here can enlighten me
