Try cutting the bread with olive oil and use coarse salt for abrasive. Delish!

Dude, do you have _any idea_ how refreshing it is to watch a video where the creator has a SOLID understanding of what they are doing AND can also articulate that information to the viewer in a highly effective manner without 10,000 "ummm's" and "uhhh's"? The bonus? No obnoxious distracting twinky urban electronica music. This should serve as a template for all other instructional/DIY videos. A++++++++

Other than getting the hose connector turned around (watch out for that one), the machine is simple to put together and use ukposts.infoUgkxfQauTxLT0JLSvqkq10rD79TU4k0Vz8zP . And very nice, too. I'm surprised at the power-it's more than we'll ever need, and we've not even used the most powerful setting yet.I've cleaned off a dirty concrete porch to get it ready for sealing, started to clean siding, and I know this pressure washer will be terrific for cleaning tools this fall.The only issue we had is we had turned around the hose connector, and it leaked. Once it was on correctly, though, we had no problems with the connection. Just remember that the end with the green knob goes towards the hose. It's obvious now what we did wrong, but not necessarily obvious at the time.

The only channel where he tells and shows the end results within the first minute and *doesn’t do any sleazy dirty clickbait cliffhangers or titles like even our favorite channels like tech ingredients and practical engineering or medhi or NileRed do* . What a breath of fresh air this is. There’s nothing else like it. Except maybe AvE but that’s different lol

finally a way to slice bread for the modern man

My present technique for producing soggy bread isn't nearly loud enough. This is perfect for me.

Hi Cody, we have a waterjet at work that I have access to. If the tungsten carbide focusing tube gets clogged again, try removing it, and assembling it in UPSIDE down. Then run the waterjet without garnet. This can unblock the focusing tube sometimes. Thanks for sharing.

I love that you begin with a brief motivation, then show the results, and then go into a detailed explanation. Seeing the result at the start gets us up to speed and makes the explanation much easier to grasp. Cheers!

excellent! I bet that was a lot of fun to put together.

Its been too long. Good to see you back with a new video. Please don't leave us again.

A great deal of care is due around high pressure liquids. Around the cutting nozzle is obvious, but a pinhole leak in a hydraulic hose can be extremely dangerous. Don't ever search for leaks with your hands (or any other body part). Any injury from high pressure liquid systems warrant an immediate trip to the ER and likely emergency surgery. Jet injection injuries are no joke. Cool project idea, just worth the consideration in a safety arena that a lot of people aren't aware of.

I keep thinking I should do this! I run a waterjet for a living so I have a surplus of discarded parts. Love the ingenuity, thanks for sharing.

The water does play a very crucial role in itself actually. It serves as a coolant while simultaneously serving as a medium to accelerate the abrasive particles with. A friend of mine who works at a metal workshop that both had a laser cutter and a water jet cutter (heavy duty variant that they used to cut through stainless steel plates that were inches thick) has told me that you get more precise cuts at the microscopic level using the waterjet, because even a fine tuned laser cutter creates irregular burns in the cuts, that might not be noticeable to the naked eye, but will get noticed during quality control and assembly of the manufactured parts.

"I wonder what would happen if I switched out the water with mercury"- Cody wonders aloud.

Commenting on a video is rare for me but I want to let ya' know I really appreciate you sharing your experience in a easy to understand along with the in depth details. Have a great one and thanks again!

A great video, thank you for taking the extended time to put it together for all of us!

hey cool project couple of tips though. i used to work as a hydro-demolitions operator (18,000-20,000 psi handheld water jet for demolishing concrete) i noticed at the top of your jet assembly the hose from the pump comes in at a 90degree angle with the gauge above it. if you swap them around the water wont need to make a hard turn. in these types of systems reducing the number and angle of bends can greatly increase efficiency. i would also suggest a short hose (1meter or so) or at the least run the hose out in a straight line, if it needs to have a bend make it a nice wide radius. the result of bends etc causes friction in the movement of the water against the hose wall. in my experience when we operated our water blaster with a few too many bends, the water going into the pump would be ~10c(or average cold water temp) but the water coming out of the nozzle of the lance(gun) could be something in the order of 50c+ while at the same time having a noticeably lower pressure (and velocity). bare in mind most if the time we were operating the lance 80% of the hose would be submerged in the ocean. thus we went to considerable lengths to keep the 40meter hose as straight and bend free as practicable. cheers hope this can help obtain some improvement and efficiency

No hmm's and ahh's.. Straight talk. And to the point. Great instructions and in depth information. Well put together. Thanks for the vid. Well done.

And the water prevents dry sand from turning to a cloud of dust, making a cleaner work space and it creates a more parallel jet of abrasive. Thanks for sharing your research and experience in this. it is very interesting. It's great you have the interest to nut it all out and build a working model. I have often considered using one of the four cylinder pump unit for spraying various chemical mixtures on farms which are driven by a power take off from the tractor. Sadly the few units I was lucky in finding for me to have, got nicked out of my shed. Used for poisons or fertilized water mixes from a big plastic tank .. but what you covered is a real treasure to the guy that is going to do this build. Or buy an entry model. Much appreciated 👍

I also had to look away when you fed it with your hands. That gave me chills. IF you slip, and that jet hits your hand, you might lose it... or worse. Great video, and glad you didn't get hurt.

A new Applied Science video?! My day has been made!

Miss your videos Ben! Thanks for still uploading even though life is crazy busy!

Thanks for being practical about the typicality of positive and interruptive components of the same system, and awareness of when you're pushing limits, what's overkill, and comparing typical solutions with modifications. I'd love to see a small holding tank with the motor working so hard, and splitting that spring-in-series mod into a two stage limit.

Your SunJoe shopvac looks like a combo of Mike Wazowski a Minion and is pretty flippin' wild!

By outfitting your cutter to a CNC you've created a nice little business niche for yourself. Great job!

I've been pondering doing something like this myself, awesome to know it works! Someone could do well to make a conversion kit for this purpose. I'd like to see something with a narrower nozzle

Great video! It has all the BEST qualities! I really enjoyed it and look forward to watching the next one!

This is probably the best video I've seen on UKposts. I hope others will take note! Thank you very much...very thorough and informative.

Thanks for this video! For years I have wondered the specifics of waterjets, and also how low in pressure you can go. Your work answered so many questions. Thanks again!

Loved seeing those high pressure fittings on something so commercial. At work, we call 3000psi "low pressure". Could have gotten away with SS NPT fittings. Also, take a look at Swagelok fittings for systems below 10ksi; really nice quality, no leak design, and no coning-and-threading the tubing.

Another fun continuing education course from Professor Ben. Prof. Ben is my favorite mad scientific educator. Who among us has not learned a lot from this crazy mad scientist and brainstormer ??

As my girlfriend wants a new bread cutter for christmas, I guess I have to build it now. Best kitchen appliance ever!

You wouldn't catch my fingers anywhere near that!

This is the best thing since *dry* sliced bread

Love your video...I subscribed! What I like is your calm explanation of things...it's like therapy after a hard days work! Better then watching cable!

Impressive Engineering! Most people wouldn't know how much you would have to know...or how to figure out to do this I cant wait to see more! Hook it up and start cutting! So you might have a slower cutting speed than the big waterjets but im sure it is impressive. My Son uses a HUGE Stone cutting one and occasionally uses it to cut steel

You have the greatest job ever - tinkering endlessly!

I have that same pressure washer. I might not build a water jet cutter but I sure as hell am stripping off the housing, what a bunch of wasted bulk to make it look cool!

hmm seems like a good summer project. I don't really have a need for one but the person with the most tools in the end wins...

"Being behind a gun is typically safer than being in front of it"

I never thought water could cut anything !!! Amazing

When I watched this, I thought for a second that this would be safer and cleaner than a laser cutter. Then I read some of the other comments, and thought again... You are a brave man!

Am I the only one who things that pressure washer looks like Mike Wazowski from Monsters Inc?! @1:55

High pressure butter jet for bread!!!! do it for the views!

It's 4am and I just woke up from a dream where I had a 100m tower to pressurize water for water jet cutting. Did the math, turns out I'd need a 60km tower to reach industry level pressures, so that dream will stay a dream. Glad there is a diy proof of concept here, so at least I can get one now that I have the desire. Thanks for the video.

Many _abrasive particles_ do damage to lung tissue, so using water to drive them also aids keeping them out of the air where they may be easily inhaled. *P.S., this is one of your very coolest projects ever. How I missed it is a bit of a mystery, considering I always eagerly watch all your videos.

I love how much you emphasized safety in this

Great video as always Ben! Had a good chuckle at the, "ups the pressure, pump starts to leak, pulls over 20 Amps part." LOL :^)

One of the best narrated videos I've seen.

That`s so cool I didn`t know you can make a waterjet cutter from a pressure washer. Great job.

"Yeah, we're running a bit over spec. Don't worry, though, I added a fan."

Great work as always. You are a thorough and committed scientist and experimenter. Please be careful with that jet of water!

I wish I could spend a day and tour the lab. It would be so interesting and I would probably learn more than in any class.

this is one of the most amazing innovations

"it would be nice not to have this thing rupture and spray water and shrapnel all over my garage..... and me" priorities XD

This is the holy grail for hobbyists, I've been waiting for a decent setup for a long time might put together a small setup to play with.

Luckily a good friend of mine got a water jet cutting machine about a year ago. Man that thing is awesome. I have had him cut everything from foam to titanium. Never an issue

Satisfying to watch even though all those imperial measurements were starting to do my head in. This video inspires imagination which is the main aim, I presume. Isn't it an incredible time in history to have access to information on anything to think outside the box?

Thank you so much, your video is amazing, I was raised in a junkyard and used to make things from parts as well, however I am not as intelligent as you! LOL Keep up the good work, well worth following.

Nice!!!! Great explanation!!! Always count your fingers when done cutting.....

Got this video as a recommendation after watching Fireball Tools unboxing and demoing a Wazer. $9k+shipping+taxes for the no-legs 230v model means a pressure washer conversion is still intriguing.

I learn more from these videos then I ever did at school

This is awesome! Thanks for taking the time to share in great detail.

Really good explanation and demonstration. I think this is Genius at work. God continue to Bless you sir.

Great work, well done. You explained everything just beautifully.

I work for Hypertherm, which as you know owns Accustream. The beginning of this video had me cringing as I would never put my hands so close to the jet haha. In any case I really enjoyed this video and love what you did here.

This is awesome. I wonder what the cuts look like under your electron microscope.

Excellent video , I knew there was a simpler way , it should cut glass also . Thanks for doing the leg work .

Wow I get you do all kinds of neat projects. Keep them comming.

Excellent explanation - you're a good physics docent as well as diy-er. Nice to see the science behind it explained as well. Thanks!

Great video. Actually, high pressure lines can be extremely dangerous. A pin hole leak could sever a limb or put an eye out! Remember you are cutting hard materials with this device.

Ingenious design,Sometimes that type of tools required..

you r so clean , clear and to the point. what an idea !!! Love you man from PAKISTAN !!

Wooo, finally a new video! I'll watch it later, though. It *always* makes my day and brightens up the mood and since this one isn't ruined yet, no need to waste a perfectly good video. :D EDIT: Watched it anyway, I was too curious.

Thank you for your time and effort in making this information available. I run a small fabrication shop and not even in a million years would I be able to afford a commercial machine. Thanks to you water-jet cutting seems within reach. I wonder if pressure could be increased by using a gasoline powered pressure washer?

It's not my fairytale, but it's fantastic idea... If I ever have my own workshop - I will build machine like this! All the best!

THIS IS EXACTLY WHAT UKposts IS ABOUT!!!! Great explanations/scientific vulgarisation. Down to earth, straight to the fact; Dam this is great stuff. More than 2 millions views, 430k+ subscribers, EXCELENT video, you just highly deserved it. Thank you from Québec, Canada

Really cool! What advantages are you shooting for out of a waterjet cutter vs. a laser? I was reading about the differences and was surprised at how nuanced they were.

The additional fan does not appear to have as much flow capability as the aluminum one on the original motor. If I'm correct, the added fan adds nothing to cooling the motor and may actually slow flow down.

Awesome idea bud! Great video too! Being someone who loves tinkering, it caught my attention for sure!

That was absolutely incredible! You must be a genius.

Awesome!!

High pressure water cutting into your skin is more then not good. If high pressure anything breaks your skin you better get your butt to the ER in a hurry! If your lucky you may only lose a limb! Also glad i stumbled upon this video. Never thought of having a waterjet before and now i am inspired! My 5000psi washer should do a nice job to :)

I am watching this is January 2020 and hope you have taken you knowledge and project to the level where you have produced a low cost design that you are rewarded for you time and knowledge excellent work.

Me again. Worked in a company making molded plastic cups for fruit, all hydraulics. Had a hose blow out extremely high pressure. Oil sprayed all over the shop. Clean up crazy. High pressures nothing to fool with.

building my new bread slicer now, thanks for the idea. :)

Very interesting, thanks. I have used my cheap pressure washer to clean masonry and painted walls. I was surprised at the abrasive power that they have. So getting them to cut through materials is very interesting by combining sand in a venturi effect. I am thinking to go get some beach sand to experiment with :) Also try making a sand blaster tool with an air compressor/water jet.

Pretty dang cool setup... Great video!

very well explained ! thank you for sharing ! really nice stuff here

That would be great for cutting odd shapes in non-tempered glass.

I dont think the fan is doing anything for you. It could be causing a minor restriction of airflow. Other than that your project is pretty cool. Especially the part about the loader valve and cutting tip.

awesome video. absolutely clear what you are talking about, all the time. super well researched. just awesome

Great stuff brother! Thanks for sharing your great work 👍🏻

As my old man used to say to me, (when I actually did something he liked).."your a smart F**K, you know that??" Laugh!! I haven't heard it in 17 years now..but I find it fitting for You after seeing this! Very cool you smart F**k, keep it up! Great video production as well...thank you!!😀

Hmm, what would happen if you cut bread with that water cutter, buu replaced the water with garlic olive oil 🤔

Love this a must for in the future. Look fwd to ur cnc cnt project.

Excellant description and explanation of your build!

That secondary fan actually doesn't increase cooling at all. If you put ten identical fans spinning at the same speed back to back, you get the same airflow as with a single one of them because their relative speed is null. Here, the added fan is actually reducing airflow because it's not as fast/high CFM as the original one. The only useful thing you can do with that fan is put it at the exhaust *after* the load, in this case the radiator or fins or whatever. Amazing project, plus I get to feel smug !

We were just going to get a new bread knife, but after seeing this... I think we are going to get/build a water jet cutter.
