[AT] OT: non-tractor covid-19 activates

Well, Cecil, that answered a question I was about to pose.  I was going to
comment that you've got a LOT of heavy iron in those machine tools, so how
do you move them around?  Answer, Gerlinger 12-ton.  And John Hall
mentioned there are guys who collect old machine tools, which made me
think... modern farmers probably say the same thing: "Imagine, there are
guys around that collect those old farm tractors!"  There's a channel I
follow on YouTube called "abom79".  He's one of those shaper guys:
