An awful lot of mundane stuff impresses you.
I'm just a simple soul but your recent discussion about knots takes the prize for mundane stuff. :)
Impressive. Want one.
:-)
If it's that good, what do you put underneath to support the thing being cut, or is there a danger it'll cut the world in half? :-)
Particularly impressed by how “coherent” the jet stays even when cutting through the bowling ball.

Na, you want a 5 axis waterjet:

If you like that, lookup wire EDM cutting
Usually a bed of nails, or a grid of slats on edge.
Ouch!
Thinking of collateral damage, I wonder what the nozzle is made of to resist such pressure.
Most machines have slats but they are full of water, which effectively stops/absorbs the jet.
A water cutting jet isn't normally water alone. An abrasive is mixed in, and the water jet is used to accelerate the abrasive material towards the work.
Ceramic of some kind normally. It is not the pressure that is the problem, but the abrasive that is in the water that does the damage (the water alone would not cut much)
Or it could be a fake post from a bot harvesting names but changing the email address. Brian
On the xmas list :-)
The nozzle doesn't see the pressure.
