Great! For more visibility of your great ideas, I could imagine you create shorts where people quickly see the function of the tool you've invented instead of making them wait until the end of a video. The ones interested in the build can check the full length video. Thank you for inspiring me. Greetings from Germany
изделие сомнительное , рабочее поле ножовки очень маленькое , что соотвественнно снижает срок службы полотна , вибрация из за кулочкового механизма огромная , что думаю мешает , держать за рукоятку при этом всем еще тоже вопрос сомнительный . для резки метала есть ленточные пилы в которых эти все недостатки давно устранены, а для дерева есть японская пила (так что название видео вообще не соответствует изделию)
This has to be the most amazingly complicated reinvention of the reciprocating saw AND BEGS THE QUESTION ' why ? ' And it is quite entertaining watching this device in use !
As usual, this is an amazing build! In order to make your saw blades last longer and to cut tougher materials, you would typically *increase pressure and reduce cutting speed* - I would therefore suggest to make a holder on top that can take weight disks (like ones you see in a gym)
Or better omit the cable altogether, set a constant speed on the drill, swap the drill to a corded drill, add a depth rod that toggles a electrical on/off switch. Just like most power hacksaw’s and bandsaws have. So it can be set it and forget it. The other flaws with this videos design is no guides to insure straight cutting
Apart from the fantastic tools you create and the precision you work with, I think the best bit about your videos is that I start out without a clue about what you about to do, that usually continues through the video until near the end, at which point it all suddenly falls into place and seems so obvious ... superb as usual 👍 I've seen you use the bicycle lever to control the speed of a drill before, it's such a simple but brilliant idea 😍
I like it! The neat thing about this tool is that it can much more precisely than one can do by hand or even in a vise. I'd have to do a lot of sanding or filing afterwards to get the edges square. That alone is a time saver.
Nice idea. But I would change a few things. 1) Detach the handle from the saw. Your hand introduces micro movements, which will result in less accurate cuts and more wear and tear to the joints. 2) Add some weight on top of the saw to compensate for the forces your hand was responsible for. 3) Add a bracket to the drill so that the axis of the drill is stabilised. At 17:40 you can see the drill vibrating a lot. That's bad. 4) Add some screws to your axle brackets. Now all the forces go through glue. Wood glue is pretty strong. But it's not made for shearing forces. Anyway, good first prototype. Keep it up.
It would have been easier to just buy a mechanical hack saw but this was an epic journey to achieve a beautiful result. To the critics “it’s not about the destination it’s about the journey”. Always a pleasure to watch your intriguing videos.
So much for almost 20 minutes of lessons on applied laws of physics (and incidentally on micro and macroeconomics - because of the effects of self-construction on private and global economic households). And psychotherapy: the knowledge gained that you can do something like this yourself... Thanks for so much concentrated know-how!
Excelente tutorial maestro, la precisión y la limpieza elevadas al máximo nivel, cómo siempre, la herramienta casera original y peculiar si qué es, gracias por compartir tanta creatividad y conocimientos, un saludo cordial y por supuesto un merecido like desde Narón (Galicia)👍🤓😜
I like the idea. Not sure if I'm happy about the device using only 50% of the saws teeth. you could probably get around it, if you are able to turn the saw blade, which would make it a pull instead of a push. what I really like is its speed adjustment. this might be handy for introducing less heat and for materials which are usually less easy to saw.
I think turning the blade wont matter because the one doing the push and pulling would be the drill instead of your hands. the speed adjustment is also there... he is just pulling the bike break to its max pull instead of gently starting it. so if you want to speed control it you can just gently squeeze on the break just like when you gently pull on the drill trigger i would put some changes tho~ instead of a bike break, i would make it a foot pedal so that i wont accidentally squeeze on it too tight and the drill suddenly goes full speed on me when i want it to slow down I would also put some kind of alignment on the hacksaw side so that it wont sway as much whiles its being pulled back and forth I also wonder if you can use gears instead of the offset arm for higher torque
I love your work and engineering but I can't say this is something that makes sense to make .. And I'm a big follower and seen all your videos. Holding the trigger and arm swing action was eppic
In General a good idea but put some weight on the upper platform, remove the "gashandle" and build a knopp aside the machine to regulate the speed. While the machine is sawing you have time to do other things! Greatings from Germany!
I always enjoy your serious videos, but this contraption you made here is just funny 😂 perhaps move the throttle elsewhere and also enlarge the aplitude so all blade is used, not only half, for those who follow these as a guide. Thanks, Creator.
One more reason why you should have paid more attention to the "laws of mechanics" in school ;-). Simple and effective solution for cutting metal to size without breaking the bank.
nice... i kind of made a saw like that for stonecutting with a diamond coated wire, for the motor i took an old recipro saw that i will now think to spice up with that handbrake- throttle. thanks for the inspiration
As an experimental tool it is really amazing (and well-built), but IMHO rather looks like a joke - I cannot see any practical benefits which worth materials and efforts spent... but I still applaud your inventiveness and accuracy in your work!
why do you need to move your hand back n forth.... only the saw blade must do its job.. make some changes so that there is no need to hold the saw arm.

@@RodrigoDoBrasilIt's more complicated to guide the saw if your hand is moved by the engine. The angle of the saw is given by the jig, it would be useful to make the holder even stiffer or longer.
Hack saws are ment to cut on forward stroke, on back stroke you need to ease the tension, otherwise the teeth will break. Industrial hack saws are made so that it raises the blade on back stroke.
increible herramienta casera, lo haces parecer facil de hacer, seria fantastico para luego hacer un upgrade de la misma, haciendola que corte sola, algo asi con un plug and play, feliciades...
I really like your videos, especially the precission of your work :) You often use tape as a construction aid and glue to fix things. Can you please write, which type (brand and product) of tape and glue you use? Thanks a lot!
Nice build, but it could be better: Having the handle reciprocating is a bit awkward; not exactly ergonomic... If you implemented a guided bar to mount the "throttle" to, you'd get a stable handhold. Much easier on your joints. This bar could run above the blade-carrier, pivoting on the back-end and being guided between bearings near the front. And you can make it as fancy as you like from there... ;-)
Could You please build something similar with a Japanese handsaw to cut thick wood with extreme precision? I really would like that, since I live in apartment and as common, we can't use powertools but only handtools... If You can build a Japanese handsaw armcut to go really straight with mm precision, would be great! Thanks...
Creativity, DIY and design etc. Is top, but in this case I feel that a small bandsaw or portaband with stand is more efficient, inexpensive, precise...

hi, a really nice idea, I thought you could make some changes, instead of using the drill as a motor you could just insert one or two motors, also, look for a way to change the saw, so you can use different saws, maybe using clamps. Greetings
l'idée est trés bien, mais je pense qu'il faudrait mettre un poids dessus la scie sur la partie mobile, un moteur électrique avec un interrupteur pour ne pas avoir à tenir la poignée de vélo... ça serait plus pratique et efficace à mon humble avis. machine à améliorer. bon courage de France!! sinon j'adore ton coté méticuleux et la précision de ton travail en général.
Very elegant, except I wouldn't enjoy holding on to the handle for the entire cut. I expected a lock or keeper of sorts to keep the tool active without having to hold the control.
you started well! with quality bearings and good quality raw material ! This invention of yours called manual Powerhacksaw ! the result you did was not very good ! 1 - you forgot the counterweight so that the saw lowers as it continues cutting 2 - to attach the drill you ended up making a more complicated system ! 3 - the WORST part is you end up with your shoulder joint and your elbow holding the trigger! in 1 week you will wear out all your ligaments ! 4 - you have made a very large saw with only 10% of blade usage cutting capacity ! I want to see more videos of you on how you would improve knowing now the mistakes you made. I really want to see version 2.0 of this project! a more portable, efficient saw, capable of cutting at 45° angles, with a counterweight, using more saw capacity, and with the drill being easier to remove, place!
If you like the video, please introduce it to your friends and social media !

This has to be the most amazingly complicated reinvention of the reciprocating saw
AND BEGS THE QUESTION ' why ? '
And it is quite entertaining watching this device in use !
It´s a fun project.
I asked myself the same question, let’s see the next production.

Сегодняшняя самоделка из разряда сомнительных. Честно говоря, не ожидал от автора такой ерунды.
Разочарование! За исполнение-5,а за идею- 2 ( по 5 бальной системе) Я понимаю,что важен процесс! Ленточную сделал бы!😅
I would have attached the gas cable where it does not move and attached a weight above the saw so that the saw blade worked itself into the material.
Or better omit the cable altogether, set a constant speed on the drill, swap the drill to a corded drill, add a depth rod that toggles a electrical on/off switch. Just like most power hacksaw’s and bandsaws have. So it can be set it and forget it.

It is really helping to keep everything natural with the precision of a machine. Perfect Combo.

Perfect for cutting parts with precision.
Easy to weld later.

why do you need to move your hand back n forth.... only the saw blade must do its job.. make some changes so that there is no need to hold the saw arm.
Exactly
The saw needs weight i think ?

The purpose is to have a correct angle, the right amount of weight and the appropriate speed.
If you do not get it, sorry.

Good work ! 👍👍👏👏 I like your video, thank you my friend ! Friendship of France
Interesting machine, but why not just install a metal cutting blade in the crosscut saw jig you have mounted on the wall?
Most of his projects are just for fun, I assume. Otherwise they would not make sense.
Fine work. But was it so necessary?
Good performance! Thank you 先生
I in awe how clean and precise you work!
Good old reciprocating saws, mostly replaced by bandsaws... still great for small productions.
Awesome idea and as always new and useful creation 👍
Hack saws are ment to cut on forward stroke, on back stroke you need to ease the tension, otherwise the teeth will break. Industrial hack saws are made so that it raises the blade on back stroke.
maybe this particular hack saw cuts on the pull
jsk is japanese
@@areyounecessary Ohhh I get what you mean now. I guess the handle serves to simplify when to apply pressure too

Not bad but slow down the cuts so you are generating less heat when cutting, add weight to the top and maybe add a drip feed for lubricant
So beautiful, so unnecesary.

You will get uneven blade wear without using the full stroke, though that will require a modification for torque.
I could imagine a whole lot of other applications for this mechanism, but none of them is youth compatible 😂
I love this, thanks for sharing

Muito bom !

Why not putting weight or a spring on the handle and place the bike level throttle somewhere else?

1. Its better to cut on an angle.
2. If you want to cut flat you have to have a lower TPI. The blade you are using is too fine or high TPI.
You’ve paid for a full length saw blade- you should use it

Why is the motor switch on the saw handle? I think that's clumsy. Otherwise a nice story.
I'd flip the saw and put the handle in the top.
