Same here. If the workpiece is springy I cut short sections to a
thousandths or so over and blend them all with a single-cut file. I
can also cut a very slight taper for a press fit this way.

Waaay back when, machinists turned metal with hand-held chisels to a
caliper fit, as woodworkers still do. A twisted or even crooked lathe
bed didn't matter.
