It would only take me a month to design my own, another month to build it, but a full year to find all the hardware. JSK's designing and building skills are great, his shopping skills are much greater!

This is a very good improvement to your last design. I do really like the the automatic stop and start mechanism. Well done. 👌

During 19 minutes I was desperate, no Double Side Tape. And then at the 20 minutes mark it appears! If one day there is a competition about overengineering with Germany, Mr JSK shall represent Japan.

Mister JSK, você é um excelente professor funcional da paciência para ensinar como se faz e como tomar gosto e jeito pelo que gosta. Nota 1000.

Absolute fantastic build, million times better than the previous one and a bit more pricy 😉. Your work is much more than masterclass, I am waiting for your next projects, greatings from Germany.

Kanał JSK-koubou świetny. Projekty i wykonanie znakomite.

Very nice design 👍you could add a small shock absorber so the saw doesn't slam down on the end stop so hard when done. Also it would be great to have a vice on each side of the saw blade to hold everything in place for larger pieces and prevent a burr at the end.

What an elegant machine. I love how you built this. Strong but very attractive. Works like you said. Power Hacksaw. Very accurate. I'm impressed. like to see someone try to cut that as well as your machine!

absolutely wonderful build, I always love to see what you do.

Another excellent example of your workmanship

В 80х работал на заводе, там такие станки, советские, трудились! Только проще и эффективнее. А это... наверное даже Festool, не сделал бы дороже.

Very cool. Probably needs a bumper/stopper at the bottom to take the impact at the end. An option would be to add an intermediary spring above the off switch to damp the shock. I could see that switch failing after a few hundred cycles. Move the switch down and add an additional L-bracket above with a spring loaded pin that when it bottoms out, just touches the switch. It would take all the impact making it last much longer.

I like how it uses the entire blade. Most of these I've seen have a short cut stroke. This one take advantage of the whole blade.

У меня сложилось устойчивое ощущение, что кнопка "стоп" долго не проживет, при такой падающей массе на нее в конце реза. А так - конструкция действительно изящная. Респект автору.

Как говорится, у самурая нет цели, только путь :) Видос очень увлекательный!

That adjustable brass bearing is lovely. Inspiring as always, thanks.

Love it. Really like the fact that the machine just does such a nice cut. Keep up the good work.

Love and enjoy watching and your willingness to share your genius with us mere mortals. Excellent as always.

That's a nice machine. Very well built.

Nice! I'd try to use it with a Japanese pull saw and use it as a very quiet and accurate wood saw.

I remember when Meccano set 10 was the thing of dreams! Thanks for this video. I didn't realize the cost of these extrusions had come down so much. I just remember how expensive the Festool ones we used at work were.

Vc e de uma habilidade , cuidadoso,, calmo, um gênio, parabéns ❤

Superb engineering and craftsmanship. Bravo!

Just sublime, the concept, creation of the parts, bolting together, the aesthetics are just on another level ... just watching this machine being constructed was fantastic, the actual operation was just the icing on the cake 👍 Some people ask why go to all this trouble when you could just buy a machine, they just don't understand the satisfaction of creating your own tools, not only that but this is probably of a superior construction to readily available machines.

I built a hacksaw for 60 dollars. The motor is dc operated and is speed controlled. I got this stuff from Taobo for only 30 dollars. It features two 12 volts lithium batteries and so it was a cordless device , which can be used everywhere without AC supply.

I like this very much indeed. No more complicated than necessary. A beautiful construction and not only that, very useful.

This is the most overengeneered hacksaw i've ever seen, and the cost of materials is ridiculous. Such a pleasure to watch though.

Always learn something from your videos. Thank you.

Nice job. Two things that will make this better: 1) a hydraulic cylinder to control the downward pressure. 2) a mechanism to lift the blade up on the return stroke.

that extruded aluminum tubing is really cool. like a giant Erector-Set for big kids.

Уже несколько лет смотрю Ваши ролики, уважаемый.. Очень нравится культура и точность при производстве механизмов и приспособлений. Равняюсь на Вас в своём хобби. Спасибо.

Outstanding video and a great design. Thanks for posting this!

It turned out to be a wonderful machine! I would add a small reservoir and coolant pump only. And of course a base to collect and filter the fluid when working

Money and unnecessary expensive parts and materials are not a problem for this guy!

👌👌👌👍🏾 - Once again you have built a technical marvel! My admiration! I am a trained precision mechanic and industrial photographer, - and the aesthetic aspect therefore always flows into my assessments. Great compliments, - great master. Many greetings from Mainz Nick

Respect for the design and for great job!

The criticism from the last saw was implemented very well. Now she's perfect. I just think that you could buy one for the cost of the materials. 👍👍👍👍👍

Bonjour Monsieur, c'est bien la première fois que je constate une anomalie dans vos excellentes et formidables réalisations. Dans le mouvement d'une scie à main, l'aller coupe et le retour de la scie se fait en soulageant le poids que vous exercez sur la scie afin de ne pas user exagérément la lame. Dans votre cas la force du retour reste identique à celle du mouvement "aller" et c'est antimécanique. Merci pour vos surprenantes réalisations vidéo qui sont vraiment professionnelle et "haut de gamme" !

I love your Content so much. Thank you for sharing your knowledge!

Great job.. No welding, lathe and expensive material.

Excellent work 👍👍👍. Thank you for sharing. Be safe 🇨🇦

A prescindere dalla utilità, rimane sbalorditiva l'eleganza con la quale sono eseguiti i lavori. Da parte mia , ho gia nominato JSK in alcuni video di altri.Resta il mio preferito.!!!

Excelente criatividade, parabéns!!!👏👍✌️

Wow, much better than the last one you made. Good job

you my friend are a mad genius , i love it

This is a really great tool that you build here. This is so perfectly made that it is possible to see it trough the magnificent motion of it. What is result is much more close to perfection than the perfection is close to herself. The pleasure of seeing you working is still there, even when you are not working with wood. It is never possible to tell what is the best : your skills, you being meticulous and clean, seeing the Masterpiece being built, the result or the quality of what it can be made with.

Great stuff from JSK as usual. Thanks. I have a mill with a speed controller, but it has a big fan blowing through the motor at full speed at all times. Running some motors at slow speed for any prolonged period may lead to overheating as their own internal fan blades do not rotate fast enough. I have an old saw of this type. It uses a much more robust blade and the vice can be rotated. Cutting 45 degrees is very useful. As always I see tools and fittings that I have never seen before. I suspect every morning JSK receives an enormous parcel of kit from various manufacturers to showcase on these videos with offers to cut iron or aluminium at any size he wants. Tools and even bicycle bits arrive as well. This must be a great advantage. Keep up the good work.

Nice work, but I have a feeling that rthe same amount of money (or maybe a bit more) you can buy a.small bandsaw which works faster and more capable ,(like cut in angles, upgrade possibilities, etc.)

Beautiful power hacksaw. We shared this video on our homemade tools forum this week 😎

Just genius! This guy is awesome! 🤯

Men now you made great upgrades !!! Good job 👍👍👍

ハックソーですね、懐かしいなぁ。　しかもリンクを上手く使った早戻り機構を採用してる所に、感心します。

Criatividade associada com o prazer do ensino e com o talento da execução. Obrigado pela inspiração de um mestre!

This is a nice tool to cut something that is literally hard to do for a long time or it has to be equally cut. But just a suggestion that the DIY limit switch you made, may cause some damage to a switch, so it's nice, but use a durable switch to make sure to less damage the switch.

Brillant as usual! I would be so interested to see how you design such a project. Do you use a software (like Fusion 360)? Do you simply draw sketches? Or are you doing this totally out of your head?

It is a wonderful piece of art! , where can you find all parts, hardware, and I think this is very expensive to built, as a hobby it’s ok. Sir you did an excellent job!!!

Moc hezké video a šikovný člověk, ale za vynaloženou energii, čas a cenu všeho materiálu mám slušnou profi pásovou pilu.

It's always a pleasure to watch you put these very interesting tools together! Nicely done. While this is pretty automatic, I wonder if a metal cutting bandsaw (Rigid makes several affordable models) might not be a better choice for this? The motor and controller alone would cost about the same I think...

Maestro lei è ad un’altro livello, da piccolo mangiava latte con i Lego. I miei più sinceri complimenti

Something most people fail to acknowledge, a power hacksaw is so much QUIETER than an angle grinder, more accurate with a narrow kerf so less material waste. This isn't a cheap project but a good power hacksaw (if you can find one less than 75 yrs old) or bandsaw isn't cheap either

PARABÉNS DE BRASIL!!! Seus projetos e seu capricho é incompatível.

the cut is astounding smooth

While horizontal bandsaws do exist, this has so much more whimsy, while still managing to be practical.

Absolutely great. As always. 👍😉

It’s not DYI, it industry level!!!❤🎉

Thank god this man’s inclinations lean more toward diy tools rather than world domination… I mean let’s face it, the very last thing we need right now is some evil scientist super villain type running around building death rays or mind control serums or any number of the countless ideas beyond the scope of my feeble understanding…. Yes… may we all give thanks… Oh yeah also, another amazing upload brother! Beautiful work as always

Das Sägeblatt sollte mittels Bohrwasser - Kreislauf gekühlt werden. Eine Auffangwanne mit Pumpe wäre erforderlich sowie ein Sieb. Eventuell ein Stärkeres Sägeblatt. 👍

I love this gold coin cutter, just what I need

Que projeto incrível, a máquina é perfeita! 👏👏👏👏👏👏👏👏👏👏

Amaziong tools. Amazing job but very expansive

Beautiful build as usual. Any idea what all that hardware, motor, and assorted pieces costs?

Даже балансир прифигачил, ну все... Мне вернули веру в людей

Me encanto ! Ya podemos hacer nuestras momedas de oro !

Parabéns pelo seu projeto bacana e perfeito do Brasil 👏👏👍👍🇧🇷🇧🇷💯❤️

His hands always clean, no matter what he's building😅😅😅

What a great machine I would add a sponge to the side where the blade rubs against to add a few drops of oil

Great job dude! Keep up the great work!

Outstanding and impressive work of art, most kind of you for sharing it with us, unfortunately a tool like that is not in the market or I haven't seen it, indeed a great very useful tool, from the endless summer paradise Puerto Rico Jesus Torres.

Really nice build. If you put a course tooth blade on you would cut 40mm brass in less than 2 minutes.

1 -- looks as though it could use a vacuum hose to suck up the metal dust. 2 -- might be interesting to put in two vices, and a number of hacksaw blades, to allow it to do multiple sliceouts at once. Might need more weight on the outer edge to do that quickly. 3 -- might, perhaps, use an oil sprayer/dripper at the cut spot, to help increase blade life and reduce heat buildup. Long vid, good work, as usual, sir!!

It is Awesome , great Work....

Riding horses backwards was epic then

very amazing video, thanks for all the tricks 🤝👏

Salutations respectueuses. Tout simplement, parfait. "La Force, c'est la Connaissance".

Une vidéo de qualité pour un outil de qualité 👏

Perfeito, excelente trabalho, parabéns! Se me permite apenas 2 chamadas de atenção que julgo melhorar; 1º através de um excêntrico, ou outro sistema, que faça levantar a folha de serra para quando a mesma recuar. 2º no final do corte para não dar esticão ao descair, aplicar uma mola ou um perno roscado com porca para regular o final do corte. Cumprimentos

Amazing.. I know they're countless craftsmen around.. it's an hightech industrial grade machine.. bit unfair to call it "homemade" though it is homemade.. great job done by those skilled hands ..👍

Great work, I really like this version. All its missing is a lifting cam and maybe a coolant mister.

Really good, but what i miss is a feature to lift up the blade a bit when it strocks back. Without that, the blade will be wear out much earlier, the more if u saw steel.

Exelente trabalho mesmo viu mestre, apesar do gasto, 🤜🏻🤛🏿👏🏿👏🏿👍🏿👍🏿

Bravo!! exelente!! es usted un buen matricero!!!. bueno... es que veo su trabajo y está mas que logrado la finalidad de la herramienta. Si me permite usted hacerle un aporte: la hoja de sierra trabaja en un solo sentido, hacia adelante, ayudaría a la descarga de la viruta que en el retroceso deje de hacer contacto con el corte. Veo el juego de brazos haciendo que el movimiento circular se convierta en lineal. En primera planchuela que va tomada al motor, uno de sus lados es utilizado para transferir el movimiento, es del otro lado, de la primera planchuela, donde agregaría un mecanismo sencillo para "elevar" el tubo de hierro en el retorno de la hoja de sierra. Es así que obtendremos una optimización en la vida útil de la sierra, habrá menos atascamientos de ésta porque estaremos drenando las virutas y tambiém habrá menos temperatura en el material aserrado. Me disculpo nuevamente y siento que es un aporte valorando infinitamente vuestro trbajo, que por cierto, es de mucha satisfacción y ayuda a sus mas de 250.000 suscriptores. Gracias: Franc.

Waouh, époustouflant!👍👍Joli projet

Well done Kobu...but you need to add some oil to the work piece

Nicely done Koubouson

Interesting, and very clean work.

Bravo ! Nickel chrome !

Nice build. But one very important factor . You need to use a cam follower on the reciprocating beam so the blade does'nt drag on the teeth on the back stroke. You will overheat your part and wear the blade out. The blade can only cut on the power stroke. Hope i dont come across as a smart arse.

Победитель конкурса - "Что можно сделать из обычной ножовки". Ножовку конечно жалко, кому она теперь, с дырками ...

Very clever and well done. Good video. But, you can buy a metal band saw for considerably less than all those parts.
