I just appreciate this man's ingenuity, fantastic Thanks
Le travail a l horizontale c est mieux
Clever solutions. Instead of using all-thread, one could use rod and just thread a portion of it. The resulting dogs wouldn't chew the wooden holes as much.
Brilliant work, dude! 😃
I'm definitely going to try to make some of those!
Stay safe there with your family! 🖖😊
thank you very much. I'll try again today
Very simple and perfect . Job done 👍
Are you an engineer ? All tour videos are amazing 👍thank's 4 sharing
If I could a suggest something for your safety, I would tell you to create a lock for your that hinges system. In any case, thanks for sharing your videos. It's so pressure and nice to watch. Hugs from Brazi 🇧🇷l

The threads of the bolts will slowly "chew up" the hole in the wooden bench table top. Otherwise nice job as always.
I worry about that too.
@@jisakukobo Yes, those big threads are quite sharp. Throwing them into a lathe would solve this - but we are not all lucky enough to have access to one.
I tried something similar with a simple round bar.
As a result, I slipped and did not go well.
I think this clamp is slippery because it is screwed in instead of being hit with a hammer.
Others suggested the idea of using heat shrink tubing.
I'm going to try it.
What if you don't remove the thread completely but reduce the sharpness of the threaded bolt?
Then the bolt still has some small serrations that would grip, but won't bite the hole larger because it's dull.
Edit: I'd also put a wooden Block inside the fixed side of the squared tube, as the force applied to the clamp might wear the tube.
I think the idea of leaving screw threads works well. Thank you
Sempre belli e ben curati questi video....ma sarebbe ancora più bello sapere anche che tipo di utensili adoperi con le tue attrezzature...tipo la lama circolare per il taglio dei metalli, tipo le punte per il trapano....oltre agli accessori che sono presenti x gli acquisti nel manuale web dei tuoi progetti...👍😉
I have a Woden X112 holdfast clamp it comes with a collar to protect the hole in the bench, there were similar ones by other tool companies, to stop hole enlarging over time. It would be possible to replicate this, if you had a concern for your bench. Probably depends how often you are using these, they seem a very reasonable way to hold this jig down.
JE TENAIS A VOUS FELICITER POUR CES CREATIONS.. QUE J'AI D'AILLEURS MISES EN PRATIQUE. GRACE A VOUS
SUPERBE IDEE. 👍👍👍👍FELICITATIONS . ET SURTOUT TRES BELLES PRISES DE VUES
You made me feel stupid! You are crazy simple genius!💓
Simple, efficient and so clean. Domo Arigato
Can you make one that with a addjust length setting??? Making the handle bit longer so it can be set ???? I think it Wood be a good tool for those with limited space
Magnífico tutorial maestro, unas buenas sujeciónes para el banco, gracias por compartir tanta creatividad y conocimientos, un saludo cordial y por supuesto un gran like desde Narón (Galicia)
nice
very nice 👍 professional work 👍
I hope you will share my videos with your friends!
It is not possible pass it on if we do not have the measures.
@@trinitytoo but what are the parts to make the screw down
@Mama C
I think that the size should be made easy to use according to the workbench to be used.
I didn't include the dimensions because I didn't think the size was important.
The point to note is that I do not use aluminum materials.
All made of iron.
Trinity, thank you very much for ypur information. I've already noticed about this, but it is missing from JSK-koubou the measures of the "square guide".
@@trinitytoo 👍
Buenas Noches Señor !!!! Muy buen trabajo, exelente jefe lo felicito, Gran saludo.--
Very useful, nice and strong tool... From my point you make me in love to the wood so now I prefer more as much as possible wood and just that can't be wood made from other materials like duralumin for example... I already sent you an email... All the best regards,
Thnxx very vrey tnx champ❤🎉
Резьба со временем разобьёт отверстия. В итоге эти отверстия перестанут держать предназначенный для них нормальный инструмент. Чем портить верстак, может купить струбцины?
The thread will break the holes over time. As a result, these holes will no longer hold the normal tool intended for them. How to spoil the workbench, can buy clamps?
Excelent...!
Thank´s.
Buen día gracias por compartir excelente trabajo
Almost perfect!
You forgot the end caps for the square tube.. 😉
Yes.
I considered buying from the online store but decided against it because I would not be able to complete the video in time.
@@jisakukobo .. With or without end caps the result of your projects is always impeccable! 🤝
Muy ingenioso, muchas gracias por compartirlo
Nice Job. Thanks for sharing. ;-)
Nice work! Where can i buy the steel cups used in your clamps?
In the US, McMaster-Carr. Maybe not exact item he is using, but acceptable sub. Often in the leveling foot section.
Как всегда хорошо придумано и сделано. Но на заглавной картинке перевёрнутый вариант.
EXCELENTE. Me gusta mucho tu prolijidad. Voy hacer mis propios "Sargentos" A propósito del pegamento que utilizas (mezcla de negro y blanco) ¿qué marca es? Muchas gracias.
прелестно прелестно!
Nice job. Where did you get the parts you didn't make?
HOLA Buen Video Saludos🖐
この人、むっちゃ頭良いんだよなぁー
SUPER SUPER SUPER SUPER SUPER SUPER
Thanks as always for the video. I would like to ask, is the square pipe aluminum, or stainless steel?
It's galvanized iron.
@@jisakukobo thank you for the reply!
Put the bolt on a lathe and file off the thread to make it smooth
I did the same with a round smooth stick. As a result, I slipped and did not go well.
I think leaving a bit of thread will work.
Elegant work. Unfortunately, the cost of materials, at least in Australia, is more than purchasing a ready made unit from China.
Cool 😎👍
At 6:48 unfortunately you didn't show how it is done. Other than that a great Video as always √√√
How did you make the bottom part of clamping screw?

Am I the only one who notices that the clamp in the thumbnail is assembled incorrectly?
あなただけではありませんよ。
@@jisakukobo 妻はいつも私は一人じゃないと言っています。 (少しクレイジー) 😀
🤩🤩🤩👍👍👍💕
OHS your thumb is too close to the drill, very dangerous!
👌👍🤝😎

There are not screws they are bolts

I love your work but this fashion show has to stop.
What does that mean?
If you have an opinion, speak it out clearly.
@@jisakukobo I just don't enjoy the way things get displayed. I like hard work not fashion model. Sorry...
WOW !!!!!! 🙂🌺👍 6 3 7 8
Maybe try putting heat shrink tube over M20 thread, the one electricans use, to less damage the hole in the bench?
your idea is good
I'll give it a try.
Great idea.
The thread gives extra purchase - cover the thread and lose holding power. At least by my reckoning.
or a 20mm pvc pipe lining an M18ish (i don't know the internal diameter of a 20mm pvc). A shrink wrap might end up tearing from constant abuse.
@@garvamel Pipe is measured by internal diameter...not external!
That's an awesome setup with the jigsaw, I have to give that a try. Great video!
Brilliantly simple, Gregor's idea of shrink tube over the threaded post is spot on, that'll make it work well even for benches made of soft wood
@ EngineerMike F: I occasionally use sections of used, replaced bicycle inner tubes
(they come in various diameters) as a protective lining, as well as heat-shrink tubing,
but in vulcanized natural rubber it's inherently softer.
And you can usually get them for free in bike repair shops if you don't ride a bike yourself.
Here maybe the tube of a racing bike for the threaded rod and for the clamps Pieces of a touring bike inner tube.
Coat the bench threads with epoxy to fill them in. Then spin and sand in the drill press. That way you don't enlarge the diameter with shrink tubing or a sleeve.
Simple and easy to make👌 thanks for sharing!
Simple et efficace, si tout pouvait être aussi net dans la vie 👏
Brilliant, only 4-5 times more expensive for those oversized bolts and parts than just buying a regular holdfast clamp.
Not even taking into account that you need like 5 machines running on 5 expensive / overcomplicated gigs.
I mean, if you show how to make it with a jigsaw and a drill press; fine, alright. But if you need a NASA lab to build a clamp, then it's kinda killing the purpose and wasting our time as viewers. The result is beautiful (except for the wooden block with the nut that is gonna get loosen everyday meaning a butt pain), but one has to consider if it's worth it.
Een groot nadeel, je kunt niet op de zaagsnede kijken en dus niet precies werken volgens plan.
Es muy agradable ver estos videos que tienen mucho diseño gracias
The threads will eat up your worktop - for those with a 3D printer, it's really easy to use a slightly smaller screw (saves money too) and 3D print a threaded tube to slot over it. This lets you dial in the size for your worktop, protects the edge, and still has all the strength thanks to the screw.
Парни сделал такие зажимы,просто класс, очень удобные
Waw impresionante tu trabajo maestro gracias por compartir ya me suscribí a su canal de UA-cam saludos
Sincere thanks for not ruining the video with some lame repetitive music.
As always a great idea and not to difficult to make, but i have a question, where do you buy those plastic knobs. i have searched many places, but can not find the right ones. can you provide us with a link please ? thank you in advance !!

@@acerjuglans383 Oh YES! I made some from 18 mm plywood, cutting them in a circle and then using some holesaw to create the cuts for the fingers of the hand having more grip. Used large nuts and washers and the home made handles ended up being satisfactorily resistant and beautiful, albeit they took time. But for me, that time was less than waiting for delivery of the plastic ones.
Молодчина! Дай Бог тебе здоровья! 👍👍👍
If anyone knows where I can find that star knob with the end is I would appreciate it. I’ve looked all over the internet and can not find one that large.

Hello JSK can you please tell me the name of the funny looking part that hold down the wood? thank you
Молодец ! Все четко и красиво ! 👍❤
Great piece of art.Will surely copy it.
Я бы очканул так палец подставлять под фрезу.
Anyone know what the threaded foot piece is called? Looks like a furniture leveling foot but it's much bigger and all that comes up in a search are plastic ends and much smaller and shorter.
I think it's just threaded rods, about 9mm to 12mm in diameter
Nicely done JSK! I was wondering why the turning mechanism on the clamp looks upside down in your thumbnail? Just curious...
Since the thumbnail is a small image, it is difficult to convey all the information about the work.
It is intentionally reversed to make the important parts look bigger.
Все гениальное просто.👍
I'm also curious... Does the threads damage your dog holes?
Watashi mo ki ni narimasu... Ito wa anata no inu no ana o kizutsukemasu ka?
La mejor herramienta, simple pero eficiente.
This is a great idea! In regards to the threaded rod wearing out the holes in the hardwood bench, I don't think an average user would go through enough clamp cycles in a lifetime to do that.
Specially if the user takes a bit from the very edge of the thread... simple wet or dry sandpaper will easily kill the very edge, leaving enough to hold the wood of the bench, but lessening any pronounced wear of that wood!
So simple, yet so brilliant! Thank you, Hiro! What do you think is the minimum depth of the workbench hole for good clamping pressure? My workbench top is 50 mm thick.
That should work. The heavy duty steel welding tables I've used are 20 mm thick and have 28 mm holes, although the holes are a much tighter fit with the clamps. But 50 mm for M20 with 20 mm holes should work fine as long as the clamping arm is long enough - clamp too close to the hole and you just pull the clamp out.
Шпильки и гайки стоят больше струбцины того же размера.
Получается без пионерской мудрости и смекалки ( тихо спиздил и ушел - называется нашел ) это выгодно не сделать.
Studs and nuts cost more than a clamp of the same size.
It turns out without pioneer wisdom and ingenuity ( quietly snatch and gone around - it is called found ) it is profitable not to do it.
Nice! We shared this video on our homemade tools forum this week 😎
This is great! Is the hold-down foot and knob a kit? Or did you buy the foot, threaded rod and knob pieces independently?
I combine separate products.
Who is the manufacture of the knob and foot?
@@louisrexach5863 tons on Amazon, I found them by searching 6 point knob IIRC
numero uno
Please share with us if heat shrink tube solution worked. Many Thanks. Greetings from Brazil 🇧🇷🇧🇷🇧🇷
Nice! I'm copying this but I am going to cut the wood to travel the length of the aluminum square tube to provide extra support. As far as the threads cutting up the wood table I was thinking of putting on some duct tape.
Another person suggested shrink tube over the thread, I’m going to try garden hose and have a smaller diameter bolt.
@@peterbeyer5755 I already tried garden hose, but found it somewhat on the too soft side... Another person suggested filling the space between threads with epoxi (I would use a steel-filled epoxi, like "JB Weld" as it is more resistant than unfilled epoxi...)
Nice build but the parts plus shipping doesn’t pay. 4 adjuster bolts with shipping is $40. By the time you add up all the other parts it’s cheaper to buy a hold down.
I seem to be the only one who doesn't understand how the rod doesn't lift out of the hole in the bench.
Is it friction, or does the clamping process cock the rod, in the hole, enough to provide lateral points of contact/pressure?
3:20 what is that liquid?? is it oil?
And what would you do with that piece of wood at the end, the piece of wood that is almost completely covered by your holdfast?
Bonjour depuis la France' nous sommes en pleine nuit il est 3h08. Merci pour le partage de cette idée géniale. Je cherche une solution pour améliorer la partie dans le trouve de 20 mm afin de ne pas l'abîmer par le filetage. Abonné à votre chaîne je vous remercie pour la qualité de vos vidéos .
👍👍👍👍👍👍
alguien me puede informar como se llaman estás prensas o abrazaderas de sujestion.
gracias.
Do I have to order adjustment bolts from Japan? Are there any suppliers in the US?
an other nice moment of brilliant hand work, idea, elegance like magic Thanks again ...
keren... simple mudah untuk ditiru

Excelente idea, gracias por Compartir... Saludosss
Your projects are very good, but inform the mesures of used materials.
expensive tools used to make cheap products not too practical..
