OOPS, WE MESSED UP. We weren't thinking when we ran this promotion. We will we gone all next week for training on the new waterjet. So any knife orders wont be fulfilled until September 2nd. To make it up to you, all orders will get TWO BATARANGS per knife blank ordered. 🔪🔪 waterjetknives.com 🗡️🗡️
Let me guess? You going to finally send me a wooden box of heavy long strong throwing knives a hundred of them... I have been here for years in line. Great videos!! I will hand sand them... no worries there!
please show the intensifier in depth, im really curious as to how a rebuild on the HP cylinder would compare to how i rebuilt the accustream 50s that was attached to a park industries fusion
Now that you have this new waterjet, are you going to try revisiting older video ideas you’ve done with the previous jet to see if you get a different result? Such as sharpening an axe head. Also in addition to making knife blanks, do you have the ability to do other bladed things such as katanas, swords, shurikens, sawblades, etc?
7 Reasons Why You NEED a Waterjet: 1: To make circles. 2: To make circles. 3: To make circles. 4: To make circles. 5: To make circles. 6: To make circles. 7: To cut things in half for UA-cam, and then make circles.
Designer jeans? I think you mean anti-chaps Also, you guys could totally revisit the attempt to sharpen an axe. I'd wager it would work a lot better with the 5-axis
Ok, you've convinced me. I'll take the old waterjet off your hands since you have a new one and don't need it anymore. I'll give you five bucks and a piece of string. Oh yeah, you gotta deliver it, I don't have a truck
@@punk105 I watched that one but didn't see a big filter bank. Do you recall the time in which it was shown? The pump doesn't need a ton of filtration. It's just as important to make sure it doesn't starve for input.
They can't. Major reason being it wouldn't be just garnet anymore and would be full or all the micro particles of what they have cut or thrown in the tank.
@@WaterjetChannel Perfectly Circular Cookies that are wet enough that they crumble at the slightest touch. Mushy to the point of inedibility. It sorted the weak from the strong with me and my siblings.
It was incredibly satisfying watching you pour the garnet through the hopper mesh. Please show that again whenever you need to fill it. I can't be the only one...
As someone who regularly operates a Flow brand waterjet very similar to the one you've replaced, I assure you that with the enclosure completely filled with water there can still be damage caused to the bottom of the tank. Upon changing out our intensifier it is regular practice to allow the pump to run for 15 mins without abrasive. This is to ensure there are no issues with the rebuild of the intensifier. In the past we have had an operator follow this procedure with abrasion accidentally turned on. This did leave a tiny hole into the bottom of the tank. It was a huge pain in the ass for 2 months (no on believed me when I said there is probably a hole in the bottom of the tank). So each day we while operating the waterjet another and I would vaccum about 75 gallons of water from the floor with a 5 gallon shop vac. Finally when emptying garnet from the tank during maintenance, management was talking into investigating the 'leak' (it was hard to ignore at this point). The solution to the issue was simple. It was filled with weld. I saw someone ask in the comments if you can cut a waterjet out of a waterjet. The answer is yes, all non mechanical parts can be cut on a waterjet. We have refurbished our enclosure multiple times this way. All internals (pumps, attenuator, intensifier etc...) are pressed, or precission lathed and machined. They would need to be worked on other machinery or outsourced.
How is the warehouse subdivided? Do you rent the space for your waterjet, or are you on a salaried team of workers with specialized training for each machine?
I’m un-ironically super jealous of these guys. they get to work in a fabrication shop with tons of cool toys and fun coworkers/a good boss. It’s amazing that they ever get work done but i guess it goes to show that a positive work environment promotes productivity. this is definitely the pinnacle of blue collar careers as far as fun goes (aside from rope access window washers and the like)
Put shit tons of painters tape everywhere and take it off after a week to sea the difference maybe leave some spot open or make a pattern of dirt osme where?
Ok you definitely need to start selling designer jeans now! Love the channel, so excited with what you can do once you learn how to program it for the 5 axis. I see nicely beveled knife blanks in the not too distant future. And yes they were all valid reasons to buy one, only reason I won't is because it's bigger than my NYC apartment.
Is there a known ratio to how much the Water jet stream ”cones” over distance? Or is there a changing focus point? Like if you cut something thick, turn it upside down, i supose the cut is wider on the bottom? Or is it?
linus452345 yes depending on what size mixing tube you are running the water will cone out at different ratios. Most mixing tubes are set for .060 over the surface cutting so that’s the point where the stream will cut a perfect .030 cut like the mixing tube. As you get further away the cut gets wider. Considering they now have a 5 axis you can program the nozzle to compensate for the sway left on the part so it will cut 100% straight from top to bottom unlike a 3 axis machine.
This is awesome, guys. Our company is buying the 13' x 6.5' 200C as we speak, are you still happy with your machine? Anything worth sharing, tips or concerns etc?
Water jet operator here, you can blow a hole in the bottom of the tank. We hired a new guy and we were teaching him how to weigh the Garnet, do the nozzle test and flow test after cleaning the nozzle and mixing tube. The default test is 60 seconds. We never do that we only run it for maybe 5 seconds. He ran all the test for 60 seconds. Pump only, water only, Garnet flow/weigh then water plus abrasive. The water plus abrasive is just like a cut and he blew a hole in the bottom of the tank in 45 seconds of the 60 second test. The tank was about 50% full of abrasive. It was high pressure at 45K PSI and .030 mixing tube.
Try cutting hardened glass:) Once we run on some stone, 1 inch thick, that took over 10m to just pierce. I forgot wath was it. Some one gave us a piece to try if we can cut it - possible but incredibly expensive... (60k Accustrem)
What’s the best way for someone to get into this line of work? I mean, if you guys are hiring I did really well on my SAT’s and I’m an Eagle Scout. Hire me, and *all of your wildest dreams will come truuue! _*some, if any_
My work just trashed our 20’ brake press and 20’ sheer. They both were over 150k lbs and went about 4’in the ground. We were limited to cutting 5/8” on it so we have 2 Messer plasma tables capable of cutting 3”
dude's i need one to cut 50mm granite , ,,,,, installable on site , , what is wastage , can water be recycled through cutting nozzle ? , , is this a viable option to set up on a site where i need to cut heaps of granite , some circular cuts , , what are safety precautions , could i cut my finger off , , , , ??????????????????????????????????, dude i need one , , have worked with granite for 30+ yrs in sydney , , currently use diamond saws with high waste run off ??????????????????????????????
So with 5 axis now knife blanks can actually come pre-sharpened correct???? Also would really like to see that type cut done on the knife blanks after your training of course.....and think that it would make another great video.....Thanks
I've not even watched it and I'm sold!! I need one and will move my neighbour out, dangerously, if they do not co-operate with my plans for my 5 axis waterjet. Bye bye shit neighbour, hello delicious and furious waterjet!
I just realized, the material supports in the tank are going to be cut to absolute ribbons after a couple hundred programs. ... Yeah, there's definitely more ways you can murder this poor baby because of the extra axis (axises? axi? You know what i mean.). :3
I used to work at a fab shop that had one of those big Cincinnati brakes. The shop owner got his hand caught in it. It crushed his 4 fingers.. OFF. Now he has 4 nubs and a thumb. My first day of working there I reported to his office, and he was on the phone, holding the receiver with his bad hand. I didn't notice until he went to hang up the phone, and it just fell out of his partial finger-nubs. I also saw a dude there sandblasting in a t-shirt. no respirator, no gloves, no hood, no PPE other than sunglasses. That was just two of the seriously unsafe things. OSHA would have had a field day with that dude. Nice guy though. he did make and install pedal extenders for a young "little person" lady when she couldn't drive her car. He did that free of charge.
Hey guy's, I saw your knife models and I think you even can prepare the cutting edge with it, please show them to the public, I didn't know you could do those things with it, very nice work I love it. Thank you.
If I show up at the work shop with a piece of obsidian needed to be cut in a 1” by 2” by 1cm rectangular prism and 300 dollars... will you guys go through wit it?
Love the channel and everything else, but I believe more in forged knifes. Better edge, smoother cut, high in carbon meaning no special machine to sharpen them. Just some background music, the light from your stove, and a stone... get intimate with your knife, get to it...
The problem with plasma cutting knife blanks is you have to cut oversize, if you cut right on your intended blade edge it would cause decard. It will harden due to the scale bit the heat zone created by the plasma actually destroys the carbon content on the edge of the blade, that's why the water jet is better for knives, if I cut any blades with plasma I cut 3/16 of an in over size and grind to my intended line. If not then where you plasma cut the edge it will not fully harden, the only reason the people say it will harden the steel is mainly cause the scale created from cutting is harder than annealed steel, but will not harden. DEFINITELY when using high carbon steel, when using some stainless or air hardening steel then not only will the plasma heat zone destroy its edge, but it will also harden it to a point.
What will you do when the tank fills with sand? Shovel it out by hand? Lol have fun. In my experience a water jet cant do anything a plate saw and a mill couldn't do way better. Besides everything you "waterjet" will have a crappy finish and need machining anyway
Can you tell me The extractor name and model. I have a flow water jet system. I been having my guy cleaning out the tank by shovels and 5 gallon of buckets on Friday’s.
I used to do concrete polishing, we used one of those extractors before to extract concrete dust from water. Welllllllllllll somebody, Frank, filled it and didn't drain/clean it.. for 2 days.. when we came back the whole thing was blown out because of the weight of the now concrete inside.

Do you ship internationally?
you should make a 13 foot long batarang to hang above the new jet!!!!!!!!!!!!

If you decommission your old one, can you cut a water jet with a water jet?
Ash White probably the whole world would split in half
I used the waterjet to destroy the waterjet
No
Now that you have this new waterjet, are you going to try revisiting older video ideas you’ve done with the previous jet to see if you get a different result? Such as sharpening an axe head.
Also in addition to making knife blanks, do you have the ability to do other bladed things such as katanas, swords, shurikens, sawblades, etc?
We can do anything like that. And yeah I’d like to revisit a few videos
Can you cut marble,granite,man made stones like ceasarstone etc
Ima ask for one this Christmas!
A wrote in? You mean a Rodham?
I have a question, what all does your company do? Surely not UA-cam revenue alone is enough to afford a $100,000 waterjet
With the 5 axis waterjet, can you now properly sharpen an axe or a knife?
I watched another water jet youtube channel and they sharpened a knife blank and when they were done it was razor sharp.
Yes, they absolutely can.
I'm just remembering their previous attempt to sharpen an axe with the old waterjet. it didn't go too well.
@@Chocolate_dragon Do you have a link, would like to watch it.
Yeah. They deff can
You’re right. Ordered 3 of them! 2 for my kids and one for me haha
I wish my Dad wouldn't have bought me a waterjet
This video convinced me. I sold my car and house and i'm buying a water jet.
Where are you going to put it?
Good job man!
@@franksavage1499 Any where I want to, I own a water jet. I sleep in the water jet.

Going out on a limb, but I think they work in that shop. As cnc operators.
I run a 3 axis waterjet and have always wanted to point it sideways and see how far it shoots.
I just got 1 on EBay.
Free shipping, door to door.
😆😆😆😆😆😆
Ultra purified water. So if you could somehow get it in a cup you'd drink it?
They did! In the Keurig video they drink it sort of
It's not 'ultra purified'. It's 1 stage filtered and softened tapwater. They have to soften it because, Utah. The tapwater sucks.
@@painmagnet1 I dunno, the last video they did about the set up, they have like 5 filters getting progressively smaller
@@punk105 I watched that one but didn't see a big filter bank. Do you recall the time in which it was shown? The pump doesn't need a ton of filtration. It's just as important to make sure it doesn't starve for input.
This might be a silly question but do you filter and reuse the garnets or is it not economically feasible to do so?
Roger DeSousa they said in the tank cleaning episode that they do not do this👍
They can't. Major reason being it wouldn't be just garnet anymore and would be full or all the micro particles of what they have cut or thrown in the tank.
I need a waterjet so I can cut perfect circle wet cookies. Justs like mom used to make.

Can you guys do water jet vs mirror,
*NO U*
