    Is there a hobby waterjet like a Wazer?

    Does the DIY hobby world have a kit for making something like the Wazer? It seems a quality pressure washer and a replacement mixing nozzle from a professional waterjet could do great things.

    On some soft stuff it would. You can chip concrete with a 6000psi washer. But no, it's not like the one they made. I am pretty sure they made an actual intensifier pump. Could be wrong

    Cutting would take a fair amount of pressure however... in my experience anything below 900 bar is rather useless.. Understand slow and average quality of cut..

    WARDJet offers several size build it yourself "kits" of an industrial waterjet cutter that cuts at 60k psi

    They had students and others putting one together at the IMTS show.

    $80K, yeah that sounds like hobby level. LOL

    Neat had no idea anyone even made a kit.

    I guess not. That's kinda surprising. I know 6K psi would cut slower than 60K psi, but it would work. Heck, the Grand Canyon was cut with almost 0 PSI. I have a feeling Wazer runs on a standard pressure washer given the limited background of the creators.

    If it did, then someone would be doing it.

    Our waterjets don't cut worth a darn under 20k psi. I sure as hell wouldn't want one at my house. Dirty messy high maintenance and high consumable things.

    Boo-ya baby! Cutting 1/16" aluminum with a $150 pressure washer at 2" per minute.

    CutOnce,
    Very interesting experiment. Actually your setup worked pretty well and for hobby CNC this would probably be pretty effective. I will have to check out Wazer as well, but using a WJ to cut aluminum would be pretty nice.

    Re: Is there a hobby waterjet like a Wazer?

    I saw the video on YouTube and then came here for more information. Surprised that I haven't seen more discussion. Nice detail on how to modify the pump. Nice he can buy the ruby insert, but somewhere in the comments I saw something about the company only selling parts to existing customers of the commercial waterjet. I noticed he is always approaching from the side. I wonder if it can pierce cleanly?

    He doesn't pierce because the sand would spray in his face if he did. What kind of control software and gantry is recommended to a hobbyist wanting to do this?

    Re: Is there a hobby waterjet like a Wazer?

    The WAZER doesn't seem economical at all. If you look at their feed rate, it can cut (max) .1875" mild steel at .4 ipm. It consumes .33lb of garnet per minute at ~$1.1 per pound.

    Imagine a simple part, say a single .1875 3 x 5" bracket with a few features, call it 35 inches of cutting. With piercing I image the cut time will be around 90 minutes. 33 dollars worth of garnet for a simple part. A 60k psi water jet could cut the part nearly two orders of magnitude faster. The same part is probably 2 minutes on a 100/hr. industrial machine. Just doesn't add up.

    I'm sure there will be some niche use cases, but it seems mostly like a bad deal.

    Re: Is there a hobby waterjet like a Wazer?

    I'll trust your math, but for hobby, the math looks attractive. Imagine that same simple part. It takes 2 weeks to get the first prototype cut and shipped to me from a machine shop. The part has a mistake, now the second one takes another 2 weeks. Then there is a design change, the 3rd one takes another 2 weeks. That's 6 weeks to do the same thing Wazer can do in one day. So I would argue that for a hobbyist, there is more value in a Wazer-like machine than a machine shop.

    Don't buy the garnet from them. It should be in the $0.17-0.35/lb. range if you buy enough. Enough may be half a metric ton however...

    Recycling garnet is possible. Much of it never hits the material.

    Good luck drying it out and separating it from the tiny material "chips". And the garnet that does hit the material has the sharp corners worn.

    For 20-25 cents a pound I'm using fresh garnet.

    Too rich for me. I'll stick to using my CNC mill for metals. What would be really interesting would be if a water jet like this could use table salt as the medium or some other graded sand to be "cheap", just for cutting wood, and then mount the head in place of router on a Maslow CNC.
