Has anyone heard of a metalworking process called "rat lapping"? I

researching an old firm and found a reference in Google Books which

this
actually a process, or is it just an OCR error when it should say
"Part Lapping"?

My dog laps up little baby rabbits and birds and things -- I think
he'd lap a rat right up.

Do you need to implement control loops in software?
"Applied Control Theory for Embedded Systems" was written for you.
See details at http://www.wescottdesign.com/actfes/actfes.html

My conjecture would be that this is an OCR merger of F and l.
There is a machine in the shop like that for lapidary materials.
But the concept of seeing how rodents would do turning through a
maze built on a vibrating platform might have parallels to human
behavior in earthquakes.
