Other than getting the hose connector turned around (watch out for that one), the machine is simple to put together and use kzbin.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.

[@tobuslieven]

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!

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.

[@robertlloyd291]

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

[@broglang9102]

Plus the cooling fan on top of the cooling fan may be doing more harm then good.

[@charlieoconnor40]

if you restrict the nozzle on a washer, the pump will be overloaded. the pump need to unload excess pressure. i wouldnt be suprised if you blew out the packings on the pump by now. there are better ways to do this. I can elaborate. 3500psi can fuck you up...but think what you want. its not the pressure what will hurt you..its what the pressure is pushing towards your bag of water(body)

[@sevenproxies4255]

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.

[@AppliedScience]

Do it! But watch out -- the safety nuts will leave the comments section on my video and start attacking yours. Or maybe if the stunt is over-the-top enough, they just give up.

[@bobsparkle9821]

Well i actually started thinking more about it if it were to be done, and i really wonder how long the pump body would last not only due the higher strain on pumping such a heavy liquid but also due the mercury weakening the pump housing and other internals by amalgam formation, certainly would be an interesting experiment, specially seeing a high speed recording of how mercury behaves in a jet at high pressures and speed. Would Cody actually do it?

[@Zoidberg227]

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.

[@Fenriswaffle]

I looked up papers on injection injuries (and compartment syndrome) and that's surprisingly scary stuff. I guess people too often underestimate the injury due to its minor appearance at first.

[@Zoidberg227]

Apparently it doesn't really hurt, either ... at first. Maybe like a pinprick. Without immediate treatment, the pain eventually becomes intractable. Unfortunately, at that point, it's probably too late.

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.

Free forming could also be done for curves and holes etc. Tile cutting involves either the scratch and snap method or diamond wheels and heaps of dust. The pros use a water bath for the wheel but the machines are big and expensive. Good luck with your development.

[@Everfalling]

so i watched this whole thing and forgive me if i missed you mentioning this but: IF YOU MAKE THIS FOR THE LOVE OF GOD DO NOT PUT YOUR FLESH ANYWHERE NEAR THE CUTTING STREAM. not /just/ because it will cut you like it cut all that other stuff, which is obvious, but it will inject high pressure water and abrasives up into your hand and blood stream. At the local maker space here in SF they attach a medical warning card to the key used to turn on the machine because medical personnel are gonna need to know how fucked you are if you somehow end up putting your hand in the way of the stream. It was actually pretty worrying seeing your fingers so close to the cutting stream like that. you'd be so much better off if you only cut yourself with a regular blade or even a laser cutter but a water jet will fuck up your shit real bad.

[@KowboyUSA]

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.

[@smallblockchevy1022]

Lower levels of airborne particles was just coincidental, it was not by design. Water was necessary for cut accuracy. That's the sole reason so why it's used. Those super lightweight, super inconsistently shaped particles would drift all over the place, and would be deflected in all different directions was not the water there to stabilize them. What was once a 20, 000ths of an inch wide cut would suddenly be half an inch wide, and take many many times longer.

[@adrienperie6119]

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 !

[@PracticalEngineeringChannel]

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.

[@AppliedScience]

Waterjet is especially good for very hard/brittle materials like ceramic, glass, carbon, and fiber composites. I think the laser would be less expensive per inch of cut, so it's better if you are only interested in cutting sheet metals and plastics. The laser cutters (in my mind) are divided into those capable of cutting metal (400W Metabeam), and not (75W Epilog).

[@seekerofyaw]

Answered my question as I was wondering if this would cut 4mm carbon fiber sheets... Perfect!... now, how to explain to my wife that we no longer have a pressure washer :)

[@Phoenix1337]

I work on a industrial Water-jet and plasma-cutter cutter daily.The main difference is the finish and the slag being produced. Both machines will be happy to cut through a 50 mm to 70 mm thick mild steel plate but with the plasma-cutter you get a lot of slag (molten metal ) forming around the initial penetrating cut, so you would have to offset your starting position pretty far away from the part (up to 10 mm), but with the Water-jet you can go 1 mm away from the part and the finish is better. if you feed too fast with both of them you risk not cutting all the way through the plate. but with thin materials plasma-cutter is much faster.

[@megolito961]

i use a high tension lazer VMI beam to cut though precious gems at my job, its made from a reconstructed ceiling fan and an LED flash light, it will chop though diamond, ruby, plastic G.I joe toys and butter, it only took 2 steps to make it too, first you pull a blade off a fan, then tape it to the flash light and pull out of the batterys then fill the emtpy flash light with salt and your done, Lazer VMI beam VMI standing for VOUCHER-MIDDLE-INTEGRITY

[@TheTwtwo]

[@Landrew0]

I'd like to know if a smooth, tapered bore would enhance the cutting power. Such a bore will accelerate fluid to very high velocities, but I'm not sure if greater pressure is also required.

[@GetRealwithMike]

The smaller the bore, the more friction and it would eventually widen the jet open. The tip is one thing I would suspect having to replace frequently but what material would you use to insure that didn't happen?

[@dionh70]

Tungsten carbide is insanely tough material, but like anything else, it will eventually wear out as you expect. There probably isn't another practical, affordable material. The trick is, if using this commercially, to be able to produce enough product to make periodic tip replacement economically viable. The narrator readily admits that he's doing this for fun, really, so cost simply isn't a huge factor for him. I'd be willing to bet he said a couple of choice words when he broke that first tip while trying to un-clog it, though.

whats the difference between this say, and an angle grinder, or a handheld router, I mean they are all dangerous.

[@robcoastalga8279]

Use an air compressor to increase pressure! You can buy a home snow maker. It uses anywhere from a small electric home pressure washer to multiple pressure washer for more volume. The main thing it needs is a high volume compressor. Which I'm sure you have already at the shop. This will increase your pressure from 2-3,000 psi to 6500-9000 psi water pressure. Needs a shop air compressor capable of 4+gpm of air at 90 psi... Just add a "venturi" or something of the sort for the addition of abrasive.

FOR REFERENCE: A ruby is just a sapphire. For whatever reason, red sapphires are called rubies. Signed - Former Sapphire Hunter

[@JohnnyKronaz]

I mean, we have a name for just about every color variant of quartz, too.

[@TheEvertw]

Sapphire and ruby both belong to the Corundum group and consist mainly of aluminium oxide. The name "sapphire" includes most transparent varieties of corundum except ruby but it is usually implied to be blue. It stems from the Hebrew language, Ruby from Roman. Historically, before chemistry, people did not realize that (blue) sapphire and ruby were made of the same material, hence the different names. That is also why there are so many names for the different varieties of silicon oxide. The ruby creating the water jet is probably an artificial one. It is relatively expensive because it is difficult to drill a small hole in it (being extremely hard), requiring either a diamond or tungsten-carbide drill. Btw, that is also why the end-piece is so expensive. Apart from tungsten-carbide not being a cheap material, it can only be machined using diamond tools. Drilling such a long, narrow channel into it is extremely difficult.

Only really thin stuff. Even high cost professional waterjets only cut things up to an inch or two. After that the hole becomes / \ shaped.

Actually, you're better off getting a water pump spray or coolant pump to help reduce dust. Like street workers use those when cutting stone in public, to reduce dust.

[@miigotu]

Just from an electrician perspective, a 15a breaker we design for 12a loads, and a 20a breaker we design the circuit for 16a of load. A 20a breaker with 20a of load heats up really quick and will trip. If you used a 220/240v motor from a dryer or refrigerant compressor motor on a 20a 2 pole, you effectively pull 40a (20a per leg) worth of HP.

[@miigotu]

So you would want your motor to pull 32a, 16a per leg. 80% of breaker capacity.

[@1pcfred]

Oh. That thing. Yes I've seen it already. It is not exactly a true 4x8 CNC machine. The water jet would be flying away from the table if you tried to use that design. That machine violates the basic definition of what a machine is. As motion is not properly constrained to perform work.

[@alanchapman6170]

Have you tried to cut steel? Particularly hard steel, speed is not a question, but cutting something that will loose it's properties if heated is?

[@throngcleaver]

The heat-affected zone in the kerf of a waterjet cut is extremely small, and that's in a high pressure, commercial machine putting out 30,000 psig or more. This 3,200 psig machine wouldn't induce enough heat to affect the hardness of alloy steels.

[@throngcleaver]

​@Brandon S How do you know what Alan Chapman knows? Are you clairvoyant? His question, no matter how YOU look at it, is about cutting hardened steel (an iron alloy that has been heat treated) that could possibly lose its hardness, due to being heated to the temperature where it starts to lose some or all of that hardness. I'm not sure if you understand how heat treatment works, but it doesn't seem like you do. If he "knows that", then he wouldn't have asked the question(s) the way he did. Are you saying that he accidentally hit two buttons on his keyboard, (simultaneously) to produce that question mark? His second sentence is as much a part of his first question as the first sentence is. Just imagine a comma in place of that first question mark, and read it again. If you want to know if it would cut steel, why don't you just ask Applied Science that question, instead of telling people what others are thinking? I have no doubt that it will cut steel, it'll just be extremely slow, especially if it's hardened or thick, or both.

[@MacoveiVlad]

So basically the whole water jet industry is laying low so no one notices the technology they use is much cheaper than they claim. And their traditional customers don't mind paying a lot for production machinery so nothing changes. And reading the comments does a great job of keeping people away from experimenting with it.

[@RunaurufuOfficial]

The thing is that when your machines is made to quickly cut various materials including metals of few cm thick then you are having a lot of power which you need to care about - and by this I mean a lot of safety standard to implement because cutting people around your machine is not good market... also handling of material itself (loading/unloading), CN control and design for long-use&live is costly...

[@MacoveiVlad]

I partially agree. But look at CNC mills. A Tormach is 10-15 thousand dollars in the US. A water jet is hundreds of thousands. There is a gradually increasing cost as the energy in the system is more focused but the cost increase slope for water jets in huge. And $20k water jet machines showing up on Kickstarter somewhat proves my feeling. If i'm correct it is unfortunate the industry reacted like this. As i presume water jets are quite clean besides the electricity they consume. No nasty fumes like lasers. No spinning chunks of metal requiring nasty cutting fluids. But i might be wrong as i never used a CNC machine of any kind. :)

Whatever happened to people being reasonable? Using logic to see dangerous situations, weigh the risk, and then proceed accordingly?

Here we have an adult (with deep understanding of the operation and physics behind this process, not to mention the dangers) doing as he sees fit. Instead of being a clipboard warrior (as we call them in the industry) why don't you worry about your own safety instead of his. A huge amount of highly interesting and highly educational topics are continually being ruined for everyone else because some idiots cant keep themselves from pointing out a small amount of danger, or idiots misusing the information, or idiots trying to replicate the information and injuring themselves and then starting litigation because they did something stupid.

[@trevormatthews7981]

Skin is punctured around 100 psi. As a demo carving a piece of steak would be a cool safety video for your water jet cutter. Some high pressure fluid injuries come from people running a hand along a high pressure hose searching for a small leak. As a hose flexes the leak path can open and a body part can suffer. Some safety information says that if that happens tell the medics to treat the injury like a gunshot wound, something they would be more familiar with.

I think they need to remove safety guards and most warning labels anyway. Then let nature run its course. Just because "pay attention" has the word "pay" in the phrase. It is absolutely free for anyone! And if you "pay attention" you can have a safe, cost efficient device. That preserves resources by using less materials to build. And far less bulky than one with all of the idiot labels and guards that often get in the way. I think that this gentleman came up with an awesome way to add a useful tool to your shop.

[@glennedward2201]

This is a remarkable test. While everyone wants to focus on safety they clearly have never experienced R&D, prototype development in a small home garage or shop where funds are limited and ingenuity has to work in the most cost effective way to come to proof of concept. You’re there now,... and have shared this proof of concept. Therefore now anyone with mechanical skills can take the simplest of this technology and utilize the knowledge to commence development into a high quality home built CNC water Jet table. Realistically you could probably develop a very nice CNC water Jet at home for a mere $2,000 (or less) that addresses the basics especially given those who have machinery who could potentially machine their own pump housings based on a more positive pressure design of the prototype; therefore potentially increasing cutting pressures for well used 3/8 alloys. Simply running stainless tubing from pump to gantry and 5000psi high pressure hose you could eliminate much of the risk and allow for gantry moment. If there was still concern a removable fabricated umbrella could sit over the top of the gantry allowing full X/Y travel while containing all fluid in event of a rupture. I have to state I am thoroughly impressed here and the simple open source proof of concept could be the next evolution in home built waterjets. If you were located in Denver I would without hesitation offer to venture with full access to our shop in developing a cost affordable home based solution. Nice work!

[@glennedward2201]

Think about this if one used a large reciprocating pump perhaps for a car wash where a high gallon per hour rating in order to maintain high pressure from a back room through 100ft plus hose with ratings at 4500psi driven by 3hp motors one may have a good basis for a home model. Taking one of those “cat pumps” and driving it with a 5hp motor one could produce extremely high pressures through that small orifice. In this case high performance seals may need to be used to prevent early friction wear. Ironically I threw 20 of those pumps away several years ago not wanting to deal with them. Would be nice to have one handy for testing.

[@pethelprc4721]

i bet your system would work really good if you started with a commercial piston type pressure washer pump instead of the wobbler type pump used in the lower cost consumer pressure washers and it would still be a lot cheaper then buying a real water jet cutter!!!
