Dear Marcin and all,

I have tried this cutting method with a chondrite about three years ago and gave up immediately.
Water jet cutting is very nice and fast, providing a got cutting surface when the material to be cut is homogeneous. So maybe it
could be tried with an Iron meteorite, but with chondrites it is not adapted to my opinion, chondrules being often much harder than
the matrix, not mentioning the metal flakes.
As you said about the test that you made, you lost about 2mm by cutting, and will lose another 2mm polishing (both surfaces I
guess), which makes a big 6mm loss and a long time spent polishing...
Just my 2 cents!
