A while back I was having problems with trying to turn 1018 on our old
B+S screw machine. I'm trying to change over to 1018 from 12L14 which
is quit a bit more expensive. I'm lookin for reconmendations as to
which oil to buy. In MSC they had the heavy duty and medium duty oil.
I'm making #6, #8 screws from 3/8 bar stock and have to turn the dia
back two inches.
