Has anyone heard of a metalworking process called "rat lapping"? I am
researching an old firm and found a reference in Google Books which
lists them as " PRODUCT — Precision Rat Lapping & Grinding". Is this
actually a process, or is it just an OCR error when it should say
"Part Lapping"?

Best wishes,

Isn't that when you set up an automated machine, come back, and find a
rat squished in the works?
