[TheForge] grinding wheel question

[theforge@mailman.qth.net]

80 Grit is by far the most popular grit for most industrial grinders.  You 
can spark-out and have a super polished surface finish of maybe 6-8 micro, or 
just rough grind to a 20 micro.  The 46 grit can be used for really ripping 
off stock.
