| I found a book from 1907 that has the most detailed discussion I have seen
on lapping. They suggest that after charging flat laps with abrasive (by
pressing it into the lap with a hard block or roller), the lap should be
cleaned with solvent, then lubricated with kerosene for use. Grooves are
cut into the surface of the lap so that grit and loose metal dont roll
around between the lap and the work like a ball bearing.
In a paragraph re making ring gages they suggest that one of the causes
of "bell mouthing" is loose material, and that when very fine gages are
made the gauge can be ground shorter after lapping (implying that the
problem cant be entirely avoided?). I assume that they are talking about
very small errors. I wonder if the mechanism that causes the error is the
lap not running true if it is "floating"? There is a consistant message that
a clean lap cuts much faster, so the obvious mechanism where the additional
grit makes the hole bigger isnt supported by this discussion.
Unfortunately in another paragraph they talk about applying a small amount
of abrasive to an internal lap as it is used...
