[meteorite-list] Flat Laps

[dfreeman]

More of an issue of the flat lap  brand is the making sure you do not 
cross contaminate the grit sizes.  I had one here in Wyoming and kept 
getting dirt blown in on the finer grits because I had the flat lap out 
of doors.  They can be messy so get a garage.  I sold my like new 24" 
for $25 so I didn't have to look at it.
To do over again, get about six flat laps and dedicate each one to a 
specific grit.  Throughly wash and wash the pieces before moving to the 
next grit size and keep the dirt contamination away.
I now use a contour polishing grinder.
I might suggest trying out a flat lap with something else before working 
on a meteorite.  Just my 2 Cents for your thought.
It is a merry Christmas!
