I saw one company recently, they have huge lathes and horizontal
boring mills. He does repair work for huge crank shaft driven presses
and makes replacement crankshafts. His raw material forgings weigh
about 20 tons. He machines them into crankshafts. He also told me
something almost unbelievable, that the forgings are X rayed! I did
not know that you could X ray a 3 foot diameter chunk of steel. The
guy is smart, very cheap, somewhat messy, does not even have any
oil-dri, just lets the concrete absorb everything. His words not mine.
