Learned this one from an old timer.
?
Four pieces of drill rods about 2 to 3 inches long, diameter
big enough to be taller than the?ways, but not so big to be cradled by the
ways.
?
Two at the headstock, and two at the tailstock, place level on
the rods.
?
Reasoning on this is -?older lathes with non-hardened
ways wear on the ways, the use of the drill rods?- is on the flat surface
that has little or no wear.
?
Been using it, works for me.
