Yours is way too over complicated and not easy to build yourself. My mates dad was a toolmaker, he built a sturdier and simpler one 50 years ago.

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!

[@Watchyn_Yarwood]

If everyone had 12 brazillion dollars and a surgical lab to work in....

[@Blade1310]

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 🤣

[@kleckerklotz9620]

@@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.

[@SomewhatAbnormal]

@@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.

[@boblordylordyhowie]

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.

[@isaacnguyen6944]

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.

[@hootinouts]

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.

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.

[@nsnnsjsnjx-lz2vs]

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.

[@jacklarson6281]

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

[@saxus]

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.)

[@saxus]

@@guitar-jo and complexity increases also the work is get slower because of the continuous transition and setup.

[@wimjanssen8270]

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.

[@saxus]

@@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).

[@brianmi40]

Yeah, but it wouldn't be DIY porn then...

[@kertahoon7328]

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

[@talegunner4414]

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!

[@werty1948]

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

[@fatroberto3012]

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.

[@jisakukobo]

Thanks for your comment. I will be making various tools. I would be happy if I could help many people.

[@uweploeger511]

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.

[@TheStuffMade]

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.

[@SierraLimaOscar]

Yes, the drop at the end looks a little violent. Maybe also move the end switch a little higher to reduce the height of the drop?

[@ravebrave8866]

actually as the machine reaches the final level it must slow down and must have a soft close system

[@tubemagpie]

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)

[@user-jz3fd8qv9c]

@@ravebrave8866 Вы правы. Желательно иметь плавный, конечный выход распилевания.

[@robertallaire432]

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" !

[@MrGUSARIK]

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

[@1crazypj]

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

[@WilliamEllison]

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.

[@michaelhompus2475]

That was my first observation too..., but it depends of the width of the stock. Can the blade cover the full width of the vice?

[@helgirgirodo]

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.

[@user-vq1gs4yx2g]

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

[@anonplayer8529]

Most off the cuts are probably non-ferrous stuff, and I think there is no need for industrial level cutting speeds😅.

[@Bob_Adkins]

No coolant is needed.

[@BTW...]

@@Bob_Adkins Industrial machines need 'coolant', which serves several purposes other than cooling.

[@Bob_Adkins]

@@BTW... That machine would last 2-3 days of industrial use, but a lifetime of home use. No coolant necessary!

[@BTW...]

@@Bob_Adkins So, you think cutting fluids are only used as coolant?

[@nobuckle40]

That's a nice machine. Very well built.

[@jonaseriksson5750]

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

[@merlinmagnus873]

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.

[@homemadetools]

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

[@jisakukobo]

Thanks

[@hawkercnc8261]

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.

the cut is astounding smooth

[@barry.w.christie]

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.

the correct motion should lift the blade on the return motion

[@yoonpark8311]

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.

[@branislavlukanovic3871]

Great job. Just forget shield fow sawdust and will be perfect.

Yes… may we all give thanks… Oh yeah also, another amazing upload brother! Beautiful work as always

[@RustamGani-pd9vv]

It’s not DYI, it industry level!!!❤🎉

[@DowningGoliath]

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...

[@randydewees7338]

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.

[@azman4749]

Using it to cut hardwood will make nice smooth cut surface

[@user-ui4cw6qc2c]

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.

[@nikthefix8918]

I guess this should also be true of Die Filer tables yet I've never seen a mechanism which takes the return stroke tooth vulnerability into account.
