I have one of these a few minutes from my house, never tried a thick
chondrite but it goes through iron slices like butter and intricate shapes
are not a problem, you could carve a gibeon into a spring if you wanted. Had
a customer who wanted to trim his Hum-V with Gibeon so he sent the specs and
the waterjet took care of business. I didn't calculate losses as money
wasn't an object but you can get the jet very narrow. As I recall, It had
gone through 2 inch iron plate with equal intricacy and they still delicate
enough to cut glass. I've seen the same model used on American Chopper and
that's what sparked my search for one. As for time costs you could carve
your name in an iron slice for about $75.

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!

How high was the cut loss?
Did you also try to cut irons?
Hi
They can cut with minimal water stream diameter 0.8mm. Here cut loses was
around 2mm + another 2mm if I want polish surface, so this is not the
most
economical method. But they cut my SAU very fast. If they made speed for
lets say 1mm per 1 minute, then surface will be much, much better.
They say that in user manual is written that they can cut iron up to
20cm,
but I think its just marketing only.
Diamond blades are still best for stone meteorites.
