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.
Simple and easy to make👌 thanks for sharing!
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)
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!
La mejor herramienta, simple pero eficiente.
Молодчина! Дай Бог тебе здоровья! 👍👍👍
Brilliant work, dude! 😃
I'm definitely going to try to make some of those!
Stay safe there with your family! 🖖😊
Very simple and perfect . Job done 👍
Simple et efficace, si tout pouvait être aussi net dans la vie 👏
thank you ! very good.
silent is gold!!
Thank you as always, teacher
Es muy agradable ver estos videos que tienen mucho diseño gracias
Congratulations, you are the master of perfectionism! "Parabéns"
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.
¡¡Excepcional!! Simple y sencillo...
Nice! We shared this video on our homemade tools forum this week 😎
Great piece of art.Will surely copy it.
Excelente, como todos os teus trabalhos! 🇧🇷
Good job 👍👍👍Thank you for sharing. 🇨🇦
Simple and functional, I like it. 👍
Muy ingenioso, muchas gracias por compartirlo
thank you very much. I'll try again today
Thou art the King of clean!
I definitely need to make some of these.
an other nice moment of brilliant hand work, idea, elegance like magic Thanks again ...
Excellent idea hack. Thankyou
Excelente idea, gracias por Compartir... Saludosss
Finally something worth while
Quelle brillante idée! Merci pour le partage👍👍
Muchas gracias 😊
I just appreciate this man's ingenuity, fantastic Thanks
Le travail a l horizontale c est mieux
Simple, efficient and so clean. Domo Arigato
Sincere thanks for not ruining the video with some lame repetitive music.
Excelent...!
Thank´s.
Buenas Noches Señor !!!! Muy buen trabajo, exelente jefe lo felicito, Gran saludo.--
Totally awesome! ... but you need to have a (clear) plastic deflector or protection thingy to cover the end of the blade - it that blade comes loose or snaps, it will aim at your eyes!
Waw impresionante tu trabajo maestro gracias por compartir ya me suscribí a su canal de RUclips saludos
Brilliant video and a brilliant idea
Все гениальное просто.👍
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.
Thank you for sharing your great ideas. Amazing
Also I wanted to say I love that you used a bolt because anyone can get a bolt from the hardware store. What if you drilled your hole at a 4 or 5 degree angle. The screw down would be angled and would snug into the hole as you tighten it. So electrical shrink tube and a slight angle might help from tearing on the holes. I got so happy when I saw this post. Please keep us informed. 😎
Молодец ! Все четко и красиво ! 👍❤
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!
/Awesome kind Sir. Thank You!
Buen día gracias por compartir excelente trabajo
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.
Парни сделал такие зажимы,просто класс, очень удобные
Brilliant! Thanks 🙏 G
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
Great idea.
Fantastic Kobu 👍
Супер идея и супер исполнение качество..❤😊
Muito bom todos os videos
Amigo impressionante muito bom
very nice 👍 professional work 👍
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.
Love this👍
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...)
MUITO TOP!!!
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,
Very good Job
🇧🇷
Are you an engineer ? All tour videos are amazing 👍thank's 4 sharing
Opa! Boa idéia!
Good Job!!!
Excelente 👌
💐Very nice. Good work 🙋♂️🇮🇳
You made me feel stupid! You are crazy simple genius!💓
Muy bueno.
keren... simple mudah untuk ditiru
Genius
Nice Job. Thanks for sharing. ;-)
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...👍😉
How is the clamp secured to the worktop? It looks great job good man
Parabéns 👍🤌👏...
Grandios!
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.
numero uno
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.
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
ありがとう
Very good 😊👍👍👍
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
Legend 👏
Nice job. Where did you get the parts you didn't make?
👍👍👍👍👍👏👏👏👏👏
So good idea
Thanks
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.
Nice looking jigs but I'd recommend that a guard be added to the top area where the jig saw blade is darting up and down to prevent personal injury.
アドバイスありがとう
HOLA Buen Video Saludos🖐
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 👍
Please share with us if heat shrink tube solution worked. Many Thanks. Greetings from Brazil 🇧🇷🇧🇷🇧🇷
Превосходно!
5:18 , 5:39 того не стоит, можно ведь прижать и любой деревяшкой ...
Cool 😎👍
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
Buen proyecto, me gustaría que nos de algunas medidas para poder hacerlo .Gracias
En realidad, no necesitas ninguna aparte del diámetro estándar de los agujeros del banco de trabajo, que suelen ser de 19 o 20 mm... el resto de las medidas es según lo requieras...
What blade is that for the angle grinder please?
прелестно прелестно!
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?
1:52 (Tip) If people don't have a metal blade!; Blade must be install backwards unless it is for alluminum/metal cutting. Great jigs!
What do you mean?
At least I'm cutting steel, not aluminum.
Please be specific in your comments.
@@jisakukobo my appologies, I missed specific info
Super 👍👍👍👍👍👍👍👍👍👍👍👍
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.
