I stared in awe at a pretty big plasma cutting table yestarday.

I think the size was 14 feet. It was set to cut a 12 ft wide/long
piece of steel. there was a steel plate on it that had 10 inch
squares cut, each with a 1 hole in the corner.

oh, and the darn thing was over 30 feet long. yeah, 14 by 30.

And I thought the surface plate the 8 of us stood on was big.
