I've only read that in "De diversis artibus" by Theophilus Presbyter written in 1100, have you got some more up to date info on it?

When I was a machinist we called it Lapping, here is this forum they use the term different. When I was a Mechanic withe Diesel engines the old hydraulic injectors like on the Detroit Diesel engines the cones and the tip of the injector had to be Lapped. We would lay out a big glass sheet on a flate surface sometimes we would use a layout block, made of granite. I would use a perscibed medium that felt like a paste and work out any scratches on what we called matted surfaces. When I was a machinist we would use a machine. Look up Lapping on Wekipedia.
