Crazy? Dangerous? Totally awesome?May 30, 2017 at 9:20 am #34718
I just finished watching that myself. Was trying to figure out how to adapt it to the MPCNC.
Then I went and looked at the cutter head and saw just the head is $350.May 30, 2017 at 9:42 am #34723
Oh, the dreams of owning a waterjet. I have looked into this so many times. That guy did some serious work to get that working. I saw a lot of what that guy ran into, companies only selling parts to verified machin owners and such. That is what made me feel like it wasn’t all that hard to do. But the parts are hard to come by.
I think the other way to do this is with a air multiplier(?) instead of a pressure washer, it uses a compressor and a crazy little 2 piston setup to increase pressure.
This looks entirely doable right? Cheaper venturi head and maybe a little trial and error on a decent pressure washer? I want one!May 30, 2017 at 10:25 am #34728
Someone needs to come up with something that is 3D printed, combined with something from Home Depot to take these guys down a peg.
Very strange comments on that video too, about how the abrasive will enter your heart through your blood stream and stuff. Is that really that plausible?May 30, 2017 at 10:39 am #34731
Well, it is cool as hell, but at these pressures it does have a large kirf, slow cut speed, and large abrasive consumption. I think a 1/16 endmill is very equivalent and maybe faster.
If it was higher pressure it gets much faster, smaller kirf,thicker materials.
I’ll have to look at those comments but the abrasive is nothing crazy. We dealt with it a lot in school, walnut husks if I remember right.May 30, 2017 at 10:47 am #34733
Oh, I’m only interested in it for cutting bread. I don’t think an endmill would do that.May 30, 2017 at 12:15 pm #34741
I watched that part and my only thought was… great… soggy bread.
Yes. My understanding is that water at that high of a pressure would basically force it’s way into whatever path it could find. Since arteries flow easier than meat/skin, it is possible it could do some very serious damage.May 30, 2017 at 12:25 pm #34746I watched that part and my only thought was… great… soggy bread.

That is just really not making sense in my mind. Why wouldn’t it just find a pathway to the air, and escape that way? I could see if your finger completely covered the nozzle, like if you were spraying a garden hose…
I need to think about that. There must be some way to use that for good and not evil. That is a strange phenomenon.May 30, 2017 at 12:28 pm #34749
A decent pressure washer can cut you. Just water isn’t that bad for you, unless it’s a center mass or head shot. Forcing garnet into you probably isn’t good for you. Getting it I to your blood stream really isn’t good for you. You’ll be looking at blood clots all over the place untill they get stuck in your lungs or liver. If you’re lucky, they’ll lodge themselves in a capillary somewhere not too important.May 30, 2017 at 12:30 pm #34752
Oh, so nasty. I’ll stick with the endmills.
