Hydraulic Press (brake) DIY - 12 ton??

[@AccidentalScience]

The card at 17:36 has a load of typos, in a single word it is wrong. Sorry, I apologize. 1) the strength is expressed in MPa (not MPa/sqmm); 2) the multiplication of the area by the pressure (176.7sqmm * 240MPa) gives Newtons (N) and not megaPascals (MPa); 3) the gravitational acceleration is 9.81 [m s2] and not 9.88. Also after a review making the video where I show the calculations made to have an idea of the strength of the structure I've noticed a further error: the weakest point are the upper welded joints, not the pins. Give a look at the video: kzbin.info/www/bejne/fmKZqplol8-Xpas

First time seeing a DIY press with capacity details clearly done for viewers to see, doesn`t look like accidental science to me... great job sir.

[@sibalogh]

Apart from your welding skills you are very practical and dexterous with great attention to details....Well done!

[@AccidentalScience]

Thank you mate.

[@olivertaylor4779]

Did you watch the video, he's running beads, this is miles better than most other u-tubers who make these construction videos only use tack welds -badly.

[@MrCubflyer]

We are not all professional welders however if the heat is right they hold fine ,very nice press for light duty work most people need in a home shop.

[@simonmorneau7933]

Very nice professional work!!!👍🏻👍🏻👍🏻

[@allenmckinney9533]

I like the idea of using the wheels. I'm making a 50 ton press and I think I'll use that idea.

[@DXT61]

I made a press for the bench. It's not as nice as yours but i find myself randomly smashing stuff. Didn't realize i would like crushing so much. Even ground a tip on one extension just to poke holes in stuff.

[@ivanm.3522]

The bending toolset are gorgeous.

[@AccidentalScience]

Thanks mate.

20:10 это огромный бонус для тех, кто не переделал свой домкрат вверх тормашками. this is a huge bonus for those who have not remodeled their jack upside down

[@esesilva6990]

Ficou xique a prensa , parabéns pelo projeto.

[@antoninperbosc1532]

Great Job I like your press, let me do just 2 observations about your weld : 1) I see that you have som tiny hole on your weld : What rod diameter that your weld you use a 4 or 3mm rod ? because I usaly weld this type of metal width with 4 mm rod but i move slower than you and follow the bath -> i get 99% time perfect weld without the need to grind weld. 2) Save your lungs -> Find an old vacum cleaner extract turbine put it in a water proof box outside put flex pipe and extractor dangerous fumes from your garage ! Thanks for sharing with us your work !

[@AccidentalScience]

I use 2.5 or 3 mm rods. The problem was with the welding machine that was designed to work on a 60Hz grid while here in Europe we have 50. After this video I bought a new inverter machine that allows me to get far better results. About fumes I have a fan that pushes fresh air from another room and the garage door is always open when I weld. This is not visible on camera though. Thanks for your comment.

Super workmenship amazing talent this will be imitative by the younger generations skill

This video and the job was awesome. Congrats mate.

[@stefanandersson3774]

Very well done! Just love it and nice colour

[@tomisp77]

Great Job ! Very excellent press !!! Congrats

[@AccidentalScience]

Thanks

[@KEPKE]

I liked that press have multiple uses, but some parts was to over-complicated. I don't like how rollers was used.. but that's your unique and made by you.. i still had none.. probably my will be worse. ;) if i ever made one. Still big thx for ideas ;)

[@richardwallinger1683]

excellent project and super useful bit of kit .

[@AccidentalScience]

Glad you like it!

[@luiscanalesnunez1846]

Hi Mr. You are mounters congratuletions 😊

[@kundeleczek1]

Very well done. I will copy your press.

[@ak-leinedition5250]

Wow очень хорошо 👌! Такой же буду делать . Вообще брутальный молодец 👍

[@ronbianca9722]

Very good! Where do you get all the metal? Are you near a shipyard?

[@AccidentalScience]

I'd love to have a shipyard in the nearby, sadly I had to buy it.

[@rc166honda]

Love your work, subscribed 😁

[@luiscanalesnunez1846]

Very good Ing. You are mounters.

[@OverTheEdge68]

Fit and Finish with a buzz box/stick welder? Skills! Nice! Peace!

[@rodneyforst2344]

I realise that it’s late, but the welding is not very good, I wonder if it’s fallen apart?.

[@AccidentalScience]

I was aware of this problem. Look at this: kzbin.info/www/bejne/fmKZqplol8-Xpas

[@breadbasket8371]

I`m trying to work it out in Psi so that I`ll know exactly how to do the welding of mine. Tensile strength and others are also given Psi in some countries....

[@AccidentalScience]

If you watch the follow up video you'll get easier data to convert in psi. Tons is a jargon to call pressure expressed in kg/mm2 or better in KN/mm2, since pressure should be expressed in MPa. So for example here I calculated 170KN of maximum force (given the effective area subject to the force exerted by the hydraulic jack, which by the way is not capable to deliver). From there you can calculate the pressure in psi: divide the force in KN [kilo newton] by a square inch in metres: 25.4mm(per sqi) = 645mm2. Divide 170KN / 0.645 = 264MPa [mega pascal]. Now let's convert MPa into psi [pound per sqi] wich gives 38290 psi. Et voilà! 🙂 Oh, another little detail. Hydraulic jack sold in Europe, where psi is just a character from the Greek alphabet, are often rated in tons, which in metric countries would be meant in ...metric tons per metric surface area. But I'm pretty sure they put imperial tons, so a 6 tons jack would be a 6 (imperial, long) tons per sqi, thus 13440 psi. Best part comes with Chinese made products where I'm confident to think they put *metric* tons per squared inch! What a fun! 😃

Brilliant

[@hackjeux8771]

I like your work and your clean work shop and when you work calm and good thanks

[@AccidentalScience]

Thanks 👍

[@juanmatamorosdelacruz7551]

Desde Huancayo Perú, felicitaciones excelente trabajo, me gustaría adquirir un prensa igual, saludos

[@AccidentalScience]

Gracias y saludos desde los Alpes.

[@bapt526]

so can it bend a flat ?

[@rlm98253]

Well done, sir.

[@josesolanomartinez156]

Cuento me costaría adquirir una prensa, que usted me la hiciera

[@AccidentalScience]

Sorry, not for sale. It's not my business. You can purchase plans soon through my website, though.

[@breakingtoast2255]

I like watching these videos very good

[@pmarshall3130]

Have you tried the lower level with the return springs thay looked like they were nearly at the max on the top level

[@AccidentalScience]

Yes of course I did. They are not at max when on top level but nearly at 20%.

[@Artines999]

top molto utile possibile ricevere dimensione dei singoli pezzi ? grazie o schema con indicazione . grazie molto

No, dispiacente, al momento non disponibile.

[@natanaeltillvitz]

Porque a coluna de sustentação nao ficou virada pra dentro . Ai podia descer o suporte do macaco por dentro da viga u. Dando mais robustez a maquina

[@snoopu2601]

Endless idea's of the adapters you can put on that press you can even bend pip make some pip connectors to bend pip, press cills, bearings, yup I can see that tool coming in handy if you are an engineer, mechanic, welder, and just like to CRUSH STUFF lol

[@atphan9663]

tôi đã xem . và không hiểu anh làm thế nào từ 6 ton lên tới 12 ton như vậy ???

[@AccidentalScience]

12 ton is the maximum force the frame can widthstand, 6 ton is just the hydraulic bottle, that could be changed with one more powerful up to the limit the frame can widthstand.

[@atphan9663]

[@snoopu2601]

I always wanted to make one if I had all the material for free. For me to buy all the material's and compared to what it cost at Harbor freight would out weigh making one. I know making one would be stronger and better.
