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!
Spot on Bob. I've watched this guy for years now and he always amazes me with the parts he uses. I'd have no idea where to start shopping where I live.. That extruded aluminium or whatever it is appears quite regularly but I've never seen it anywhere else but on this channel 🤣
@@Blade1310 These profiles are industry standard. You see this a lot in factories for almost all simple constructions. Here in Germany there's a company called ITEM. They sell all kinds of different parts among those profiles. But there are also a lot of noname brands which are a little cheaper.
@@Watchyn_YarwoodI’ve built from several of JSK’s plans and they are not all brazillion dollar projects. Sure this one is pricey, but if you need a tool like this one, you’d pay significantly more for the store bought version and it wouldn’t be nearly as well built. As far as the cleanliness goes - we should all be striving to improve our work environments. Less clutter is more productivity.
I must admit I envy him for being able to find the parts but also knowing what they are called. Most times I am trying to find parts for projects, I know what I want but don't know what it is actually called, so, I spend days trying different combinations until I get close then refine from there, mostly, I compromise.
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.
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.)
My thoughts exactly! If I had to buy all these parts in the Netherlands, I could buy a nice pre build alternative. And how often do you need to cut that thick rods.
@@wimjanssen8270 If you make things with a lathe then very often :) Also this could be used for various things, like cutting aluminium profiles, steel square tubes, tubes, or various profiles, etc. But if you do that, then probably you want a machine for it, otherwise even this would be beyond the limit. Or there are other machines. Like many woodworker use a chopsaw to cut alu-profiles, most modern tungsten carbide blades could handle it easily. (Or just use a specialized blade).
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.
Two possible refinements but I could not help thinking that one might want apply some coolant whilst cutting... remembering the machines from school metal work and the time I worked in a factory (aged 14)
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.
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.
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
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!
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!!!
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.
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?
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
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.
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.
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.
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.
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" !
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.
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...
Almost all small bandsaw types require you to "hang around", as they cut fast. Not necessarily a disadvantage, but a power hacksaw can just run in the background while you are doing other things. The other advantage is small power hacksaws use cheap readily available hand hacksaw blades. Or in this case, the hand hacksaw! I have an old Covel Excel - later sold as Craftsman by Sears - that I use 5/8" heavy duty hand hacksaw blades with. over the last 10 years I've made thousands of cuts with it, don't know how I got along without it.
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.
@@1SCme Cooling is, on my opinion, not necessary at this slow speed, but, when it cuts often material like aluminium, a lubrication on the blade can really make sense.
@@renetr6771 ...or he could add cooling water and cut faster... I do like the limit stop switch, would like to see a manual e-stop switch on any homemade shop equipment (I want to add to workshop receptacles), rest seems like overkill - these are some expensive components he's putting into this. Not sure how you would life the blade on the backstroke because its depth is changing, but you might be able to add a counterweight, moved by a cam on the motor shaft, to take the weight off the blade. I am in the process of getting a custom home with a large workshop, a hacksaw cutting machine is on my list of projects, so I am picking up bits and pieces.
That kind of looks a lot like a garage door mechanism. I wonder if you could repurpose one of those (I had one die on me a few years ago) into something like this.
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.
Nice design and build project. However, I am not sure how much all of that cost. The tool market is full of options from the high-end to "GOOD ENOUGH" tools made mostly in China that are so cheap here in the US that it is hardly worth the effort to make one unless it is unique in its functionality. All that said you have a very creative Maker with all the skills needed to make anything you can think of
👌👌👌👍🏾 - 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
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!!
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.
Das Sägeblatt sollte mittels Bohrwasser - Kreislauf gekühlt werden. Eine Auffangwanne mit Pumpe wäre erforderlich sowie ein Sieb. Eventuell ein Stärkeres Sägeblatt. 👍
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
Beautiful precision, but I’m wondering what is applying downward pressure on the cut piece other than gravity from the weight of the machines arm. Do you need to also hold the handle and apply additional down force???
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.

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.!!!
Уже несколько лет смотрю Ваши ролики, уважаемый.. Очень нравится культура и точность при производстве механизмов и приспособлений. Равняюсь на Вас в своём хобби. Спасибо.
pretty cool, would prefer to have seen all the 90º external corners rounded off, end caps , perhaps a galvanised bar rather than clean steel as it will rust ( i'm being picky I know) and at the end of the video a square placed on the stock bar to see how square it cut.... Also please put a ground on to the chassis back to the motor ground on the VFD ground wire, the motor alone is not good enough as a ground bond to the chassis. Face value This is a very nice Motorised saw. Thank you.
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 ..👍
@@cho4d .. I'm smiling you're right brother.. that's what I said that it's an industrial "grade" machine made with hands.. industrial robots can't shake while human hands do.. still produce as you mentioned novelty piece..
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
A nicely designed and well built project. Depending on the production run needs, I would think a lathe and parting tool could be more effective. A capstan type lathe even more so. I admire the design work and the careful assembly. Efficiency of production would probably dictate using a commercial machine or considering another method. CNC machining is a worthwhile alternative.
As a young trainee I was taught that parting on a lathe is the most difficult to pull off (well besides trepannig). All your settings must be perfect and then there is the cutting fluid selection that must be concocted to match the material that is encountered. . Not only that, the parting tool thickness for that material and diameter would need to be a minimum of .125 width. This width would create a lot of waste for your typical home shop. Most hack saw blades run between .025 & .063 in blade thickness. Also, take into account that most home shops don't have CNC equipment. Many years ago I bought a power hacksaw for under 100.00. I use it to cut material over .750 in dia or square. I has proven to be quite a time saver. Oh, hack saw blades can be had for pennies at garage sales. Cheers.
@@williamparker8318 Ex toolmaker here so I can happily disagree. Of course I recognise that home work and business are different propositions and often require different approaches.
Question is... how much would the aluminum frame, hardware, motor, controller etc. added up to? Would it be less than a used bandsaw? I bought mine for $100. Really nice workmanship. It was a pleasure to watch.
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.
