Very nice, but why is the stroke so short?
because the driving gear is limited on diameter. Stroke is limited to twice the radius of the driving arm bearing center point.
helut kuno that's what she said!
helut kuno very easy to extend as long as the motor has enough power
So that he can put bigger pieces in there
TS Right, but why not make the stroke adjustable, so small and massive pieces don't take ages to cut
if you lengthen the stroke on the saw, you will use more of the blade. great work as usual though.
I noticed that issue too. 2/3 of blade unused and most likely rails dont like that ether so much.
Nop
I use a Full Stroke😉😉😉
the diameter of the gear which the saw is on would have to be the same length as the saw blade itself in order to get a complete stroke. making this happen would require a new build because the body is not meant to house a gear that big.
Lucas Cole - A moveable vise, or vise jaw, would be a better solution. Then you could keep the short stroke but use more of the blade as it dulls, or he could just send me the partially used blades. LOL
Mate, you make the coolest shit on the tube!
KInda agree, colin furze makes awesome stuff too, check it out if u havent
Nice job, might I suggest lengthening the stroke of the saw a bit though
Benspeed's Channel was thinking the Same because he just uses the middle and the rest of the sawteeth stay like new
small gear, plus it needs bigger motor this is fine for small things because you can just leave it to get cut by it self
I came here to write exactly this... you could have the stroke length adjustable that way
Maybe an adjustable stroke for wide things.
I was thinking the same but it's do limiting using hacksaw blades. Large items would have to have adjustable vice, strokes etc. It's just not efficient hence why the band saw type units are regularly made and work much more efficiently as well as cutting much faster. This build is great as usual but the design is not good. It's going to take much longer to cut even longer than using a hacksaw by hand sdince by hand you can get full strokes of the saw.
nice job you can make mini lathe or milling
Кривошип короткий - заипётесь менять полотна.
Meh... not your best project. Why not a band saw?
Still amazing to watch you make it! Hell, I'd probably watch you make a sandwich!
Great to see you guys again! Seems like it's been a while!
I was guessing the same, but at the end he shows how precise the cuts are, plus, its safer
Logic Bob you don't have to be around to cut things on a power hacksaw
I would like to see the sandwich as well.
jonnoMoto the same is true of most horizontal steel cutting bandsaws
Make sandwich extreme! :D
It's nice, but you're wasting most of the blade.
It moves back and forth with equal downward force, so perhaps he intends to flip the blade after it becomes used?
Amra maybe a dinosaur? I LOVE them by the way
It's also applying equal pressure on the retract which promotes premature blade wear. There's a reason bandsaws are superior to these.
*Make it Extreme, make it Awesome*
I really like this quality build! There are comments saying that this is for small things, but that is not true. It is about 3 to 4 times faster than doing it by hand. Finally, the precision is much better than a bandsaw, especially thin cuts. I know these things because of 50 years experience. Or, I may just be feeble? Yes, a longer stroke would be desirable. A bandsaw is a very nice machine to have too! Thanks for posting! Jerry
The short stroke of the blade is desirable for larger pieces, but with this design large pieces wouldn't fit in the vice without hitting the front sawblade holder :/
I think an adjustable arm for the stroke and some sort of adjustable clamping system would be the best way to maximise what you can cut as well as the life of the blade, but this is what this channel is about - cool functional items that people can draw inspiration from :)
Keep it up guys, I'd love to see a homemade metal lathe next.. It would be quite the challenge getting it precise and rigid enough.. IIRC, back in WW2 some factories made the frames of large lathes out of concrete instead of expensive cast iron, perhaps you could use a similar construction method.
adjustable arm would only change blade placement not stroke, which would still be useful though in this case. To change stroke he'd need to modify the crankshaft/crank gear thing.
I was thinking one way would be to use a nema34 cnc stepper motor and lead screw for the motion. Then you could adjust the stroke length and the design might be more compact.
I honestly don't understand why you guys don't have 1M subscribers... this is an awesome channel!!!
Whats the point? Its cool but cant you use a bandsaw?
Good question.
its more precise and automatic i guess,but he needs to add cutting oil dispenser,other than that i dont see the point.
In my experience bandsaws (especially horizontal bandsaws) can have the blade slip off the wheels and get stuck in the part, very annoying when you walk away and return to find the blade stuck and your part not cut. You don't have that issue with this type of saw.
Fantasic job curious where the gear box and the motor came from or perhaps I should say what is it off of? Keep the videos coming!!
Καλά εντάξει Άντε Υεια! Ολη την ώρα σκέφτομαι, τι άλλο θα φτιάξουν, και κάθε φορά βγαίνει ένα τούμπανο εργαλείο που δεν μπορώ να το πιστέψω! Μάγκες το εργαλείο καράτσιλίγο! Δεν έχω λόγια, Μπράβο ρε παιδιά!
Hey guys, if you have any use for it... can you make a bigger wood chipper? like for logs... thanks ..
Like most of the comments here the stroke needs to be longer and how is this better than bandsaw or even your chop saw?? Cool channel tho
ya know there was a company that made these wayyy back in the day in the US, they went out of business because they fucking sucked.
Not your best project, sorry ! You are just using a small part of the blade. Do you really need that saw? Your circular saw seems to be much better.
Maybe it's for fun, not everything needs to be practical.
Solid build, excellent work.
Might i suggest also a drip oiler for the blade
A larger drive wheel with a series of bolt holes from near the shaft to the outskirts of the wheel for stroke length, and a pivotal vice with angles ?
for sale: partially used hacksaw blades. 66% of blade brand new! :D
or just turn them around and use that side too
класс!! один недостаток увидел: шарнир который толкает пилу нужно сделать регулируемый. тогда можно будет задействовать нерабочую зону пилы. а так работает только средняя часть пилы.
Можно зажим для детали переставлять, чтоб всё полотно работало.
тоже хорошая идея.
Можно радиус эксцентрика увеличить.
мы не врывались, мы тут были) я не смотрю Максимку.
Ты в одном комментарии под твоим видео ответил кому-то, что посмотрел все видео ДМ. Так, что не надо обманывать) И да, Я в шоке, что сам Каховка ответил) С Донецка привет.
Great work guys! But as the viewers said, the stroke of the saw is short..
7:41 the clearance wasn't planned I guess ^^
try to make a saw machine with a swift dynamo drive
Why would you need a power hacksaw when you have that wonderful yellow carbide metal saw you used to saw the parts in the beginning?
the carbide metal saw makes more heat when sawing.
Why not? Also it's automatic
Defnotdemas it really depends on the feed rate. But yeah, it is called a "cold cut" saw.
That's what I was wondering as well. I see no advantage at all over the cold saw they already have. And yeah, it's fun to make things, but it seems to me that making stuff time would be better spent making something that isn't redundant.
Although I like the cut speed of a decent circular saw. I´ll leave a question.
You guys know how much a circular carbide blade cost, right?
For the same price I can get about 70 to 90 of this much cheaper blades!
Of course they don´t last as much, etc, etc. but it´s easy to understand.
By now I´ve got white hair, but when I was a teenager at mechanical school. For bigger stock we used this type ONLY. ;-)
buena idea pero se podría poner una mesa para hacer cortes en diferentes grados de ángulo como el de 45°
Awesome job ! - Fantastic machine ! - The only thing that lets it down is that geared motor is way too slow ....You need a similar worm motor/gearbox with a faster output speed then it will be 100% perfect ! - Great video and workmanship man :-)
70% полотна не работает, недоработка
As everyone is saying, the saw could use a bit more stroke, I also noticed you could change the length of the drive rod to adjust the position of the saw. Sweet piece of work, keep it up!
Низкая амплитуда.... была бы возможность менять её...
Portugalec 88 вследствие неполное использование полотна!
Пару десятков пилов и полотно в урну полетело.
Не вижу проблемы. Приварить рычаг к шестерне, увеличив диаметр->длину хода шатуна. И всего делов
@@КонстантинОсетров-ы3ц надо так сразу и делать
Did ever something you build didnt work cause of the spray paint?
The paint creates a barrier between oxygen in the air and the steel, preventing further rusting. If anything, it *helps* the function of the things he makes!
Good question, paint never helps mine so I use rust, which also stops rust.
Lo unico negativo es que tiene poco recorrido la hoja de sierra , deberian aumentar la distancia de la manivela de giro. Felicitaciones...desde ARGENTINA...
muy bueno, faltaria cortes en angulo y una bomba de lubricacion, la mesa deberia permitir varios tramos de corte, asi se aprobecha toda la hoja de sierra
مبدع
looks ok. you are going to go through a shit-load of blades because the blade doesnt lift up on the return stroke.
Have a nice day everyone :), I would love to assist building those cool things.
Brasilia a love
Cool machine, i only know it from production handbooks. Seems like a small lightweight machine able to cut big stock.
Very nice, now make a flood coolant system for it!
Saw must be sprinkled non-stop coolant.
Says who? The blade wears faster without coolant/lubrication that's it. It's always a compromise. Cutting speed could be kept low and increase stand time. Using the "warm saw", i.e. manual hack saw I've never used any coolant nor lubrication.
Bom dia! Ficou até com uma estética agradável , funcional e selenciosa unico defeito e o cursso da lâmina , so ficou pegando no meio da mesma.
Concordo
Excelente trabajo. Como siempre. Mucha prolijidad. Pero habria que ver la manera de que se pueda hacer mas largo o gradual el movimiento de oscilacion de la sierra para aprovechar mas de la misma
very good job ..need one small pump water to freshen up the saw.. and is the perfect.
That stroke length makes this thing a huge fail.
Cutting fluid dispenser?
This. Otherwise the blade would wear out way before it cut through that round stock he put in at the end.
Another excellent invention, well done sirs.
This machine is already invented. They merely made their own version of an automatic saw. Lol
I would love to see you make a Milling Machine! That is one thing I have always wanted to do myself but I just don't have the skills yet. lol
My next build ... Needs a bigger drive gear to lengthen the stroke to use more of the blade . 😋
where you found a gear box and motor ?
some machine or something else?
If you can't afford to buy a machine, fabricate.
This is awesome.
Dear wish to give us the method of using these tools
nice job!
-Could you soon make a parts tumbler, for deburring and rounding edges of smaller parts? I'm looking for inspiration..
Good channel. Ada baiknya jika diberi ukuran pada besinya jadi bisa tau secara detail. Subscribe my channel too
é so precisa almentar o curso pra melhor aproveitar o rendimento da serra
Hey Gents!@ 9:47 you are using a steel blade cut off machine. I want one as well as the steel blades, can you help me organise to import one please?? I'm in Johannesburg South Africa.
asemas ruido y demora mucho y gasta mucha energuia
Hello,I want to ask you a question.From what are that gold buckets that you are using in your videos?Thanks.
I'm with everyone else, we wanna see a longer stroke and the clamped material at the at the Apex of the stroke.
I agree...they make the coolest shit....they should be millionaires! I guess its only a matter of time before someone with alot of money finds these guys and helps them revolutionize the tool industry with their quality...original...heavy duty tools that actually work and don't break all the dam time like half the junk out there right now!
ADD a small pneumatic cylinder with a bleed valve, maybe $10 worth, so you can adjust the downward feed.
Nobody in the comments realize you only need to flip the blade around and you will still use the whole blade.
Why is the stroke so short?
The dia of the drive wheel is far too small.
That’s what she said
But like in terms of the design, wouldn't you figure that out and then scale out?
He probably made it so he can cut wider pieces of metal !
P0tat07 damb you beat me to it
Needs adjustable stroke , but even more needs to lift on backstroke to save unnecessary blade wear. This design will wear blades twice as fast as necessary. With these mods great machine. Blades aren't cheap
The saw is cutting on backstroke - it's the forestroke which needs lifting!
Very good saw congratulate you. I know that many have opined but, mine is a suggestion, the ones I've seen bought, have a cam on the reducer that raises the saw when it advances so it does not touch and wear this way your saw will last twice, congratulations.
Отлично

Some folks might think "a band saw would be quicker" and they would be right. Why a power hacksaw? Much more accurate. Like cutting the pipe with a really short cut making a washer. Can't do that with almost any other cutting tool.
Esta muy bien logrado pero solo se puede ocupar la mitad de la hoja de cierra si corrieras la mordasa fija 10 cm para atras ocuparias casi el total de la hoja igualmente esta buenisimo y me encanta todo lo que hacen.
If you made the clamp/vice moveable, you could use new sections of the blade when those two inches get dull.
His company is listed under "Performing Arts".
Sweet. But why? You have a cold cut Saw?
Can you build a scroll saw next?
That is cool, sorry if it sounds dumb, but does it ever get hot enough that you might need some coolant for cutting?
Estaria bueno poner un dispositivo para lubricacion de la sierra.Muy buen trabajo
Legal ficou mas precisava ter colocado regulagem na base de aperto do torno pra mudar o local de corte e não gastar somente naqueles poucos centímetros da serra.
Мужики вы крутые спецы.Только руки береги, а то живого места нет.Гут гут гут
Is a bandsaw not better?wery cool project✌✌✌✌
Utiliza 1/4 da lâmina . Faz com regulagem para aumentar o vai e vem .
Boa ideia
Esta hasta las huevas....poco recorrido de la sierra....
A decent channel with decent work for a decent Laika
Very nice project 😉👍
think you need to make the pushrod adjustable in length so you can use another part of the blade if the first bit gets dull
Very awesome. I would make the back stop adjustable so you could move the work to different parts of the blade, that way you could get more life out of the blade. That and lengthen the stroke a little.
Needs more power and an adjustment to where you don't only use one small section of the saw blade. 2.0?
That's a good build, but why not just use a bandsaw?
Awesome:) hmmm... I wonder if what would happen if it went readily fast and a switch turns off the machine when the blade reaches the bottom or slows down the lower the blade is like a timer so fast when large cut and normal speed when small
Please can you make a fully automatic injection molding machine
Happy mornings to the team of make it extreme... I have seened all the projects u did.... Everything will be awesome... Friends I need one help.... I am pursuing B.E mechanical... I need exact dimension of power hacksaw .... I am going design it in solid works.... I need dimensions and material quality.... Plz help me..... Thank you friends...
I'm slightly disappointed, half expected it to pick the stock, set it at the right length and cut it all by itself 😂
It is advisable to lift the blade in return/not cutting stroke to increase blade life.
Эффективность маленькая, надо делать регулируемый ход полотна. Чтоб он как можно эффективнее работал и большей площадью.
Try to make it with stodoys plans :)
Muito bom vou fazer uma dessa para mim.
NO STROKE. USELESS .
How they aligned the saw strictly vertically?
Forgot one thing, can't adjust the length of stroke.
youre killing the blade because it doesnt retract on the return stroke
Το πριόνι πρέπει να έρθει λίγο πιο μπροστά και να βάλετε μια "μπιέλα" πιο μεγάλη για να κάνει μεγαλύτερη διαδρομή. Έτσι όπως είναι τώρα μένει ανεκμετάλλευτο μεγάλο εύρος. Κατά τα άλλα, εξαιρετική ιδέα και ακόμα πιο εξαιρετική υλοποίηση! Μπράβο παιδιά!
if the blade wears out you can just flip it and get another life out of it
what if.. now this may sound crazy.. but... instead of a reciprocating saw... instead, use a circular one.
