Building a Sheet Metal Brake
Вставка
- Опубліковано 22 чер 2018
- I made this metal brake purely because I need one for my next project. It mounts on the workbench so it can easily be stored away when not in use. It's 140cm wide and can bend sheets up to about 125cm in width. I used 70x70x6mm angle iron for the main parts.
This is a very common design, you can find many tutorials on how to build these using angle iron as a base. You don't need a mill or lathe for this, you can even build one without welding. This is just my personal take on it. I put three adjustable diagonal supports on it because if you make them this long, they won't be stiff enough unless you use some very heavy gauge material. (If the brake isn't stiff, it will make your bends uneven/inaccurate) So it's a better solution to stiffen them out using these supports, they add a large amount of structure and you can even adjust for a slight bend in your angle iron this way.

Very nice work there, only one thing that I would like to see is that the middle tension bolts, rather than the end touching the material that it has a sleeve made that locates it to one spot, not letting it walk every time you try to use it. I’m pleased that you recognised that the top clamp needed facing off on the mating side of the clamp base, therefore reduced the chance of a rad on the bent material. Thanks for showing us this, really nice job 👍
Of all the videos I've seen lately about fabricating a sheet bender or folder yours was by far the simplest and most straightforward. I love the initial usage of wingnuts and then the big hand knobs for the top bar it seems everybody else is set on using a wrench of some design .well done and thanks for posting it
Amazing tool set.....little more in-depth than your average home builder. I drool for tools like that some day...nice work!
Great job, will be a useful addition.
Nice fix with the truangulated supports, I don't think I've seen that before!
Good build.
It's on my list of projects. I may have to borrow some of your design ideas
If you use your lathe to cut through your metal rods it'll use a bit more material, but you'll likely have no need to deburr the item you are machining, and it's quicker.
I also think the supports are a bit obtrusive. They may get in the way of a double bend. You may have been able to doubled up on the angle iron for additional support instead.
Great build all around! Thank you for the beautiful content.
C'est de l' excellent travail mon ami.
Sweet. Good work!
amazing work dude
awesome metalworks thanks
Nicely done.
Great work....excellent...from Argentina.
Amazing!
Thank You.
Really awesome build! Monday morning quarterbacking, I think I’d have rounded the ends of the two stress bolts (anti bowing rigging) and welded a short piece of tubing where the bolt meets the frame as a keeper or alignment socket. Oh, and paint. I’d probably paint it so,e obnoxious blue or dayglo green to offend the eyes....🤨 not really. I prefer black, gunmetal, or deep rifle bluing.
Really nice build, though. If I ever get my life back, I’d like to built one at the level of detail you have. It is one of the most detailed and well thought out home builds I’ve seen.
aaaaaaaaaaaaaawesome. fantastic solution for the bow, I was waiting for it :D thanks for this video!!
Hey man, whatever happen to you :), No vids for 2 months
love you Sir for this great movie.
That is bad ass wish I could do that nice job
Your amazing!
Really so nice video thank u so much
Perfect my friend! Awesome yours abilities! Congratulations!!!
nice!
Good show
Nice bit of engineering! Well done Phil!
Thanks! I actually took some inspiration from your build, and yet I still ended up underestimating how much these want to flex :)
Very true, but looks like you solved the issue pretty good. Mine does the same so maybe a mod like your will help. Cheers!
Es la plegadora más elaborada que he visto en youtube...simplemente GENIAL TÍO!!!👏👍...una pregunta: que torno utilizas para tus trabajos?.ENHORABUENA POR EL CANAL.
Curious why you didn't weld in a smaller piece of angle iron inside of the hold down bar instead of making the bows on top. That would have cured the flex.
Can't hate a guy that uses his tools to make more tools! Nice, now can I borrow your brake? I need to bend up some sheet metal for a slide out kitchen for my off road trailer.
Inside the upper clamping profile, reinforcing gussets must be welded for rigidly
🎥 Beautiful work !. _ Congratulations! 👍 🇧🇷
The one dislike is from somebody who doesn't have a mill, thinking this was going to be *easy*.😂
Probably ;) But like I said in the description, you can easily make this using just an angle grinder and a hand drill. I've even seen people make them without any welding. The mill just makes it a little more... elegant

It definitely does make all the lines nice & straight, as well as the cut depths even. I know I need to make one; just need to find the time.
Very good .tankyou
Awesome video! Would you have avoided the flex with just some thicker angle or even bracing the angle with some flat bar to triangulate, I am looking at making one soon and would like to know what you think.
Good question! I thought about doing that too, basically closing off the inside of the angle using flat bar. But a lot of the time, a larger effective cross section (which the diagonals provide) will give you more stiffness than using thicker/more material. Like for example, a tube with a larger diameter will usually give you more stiffness than more wall thickness at the same diameter. But the main reason I went with this was that this was the material I happened to have laying around ;) And also because I noticed almost all the commercial brakes also have the diagonal braces. I think it comes down to the width, if you don't need a brake as wide as this I think you can get away with just using thicker walls or triangulating. This only became a problem when I tried to bend those wide sheets (120cm / 4feet). But if you have really long pieces, this solution adds a huge amount of rigidity relative to the amount of material you're using. So I guess I don't have a definitive answer.. Maybe start with your first option, because you can always add the supports later like I did. By the way check out Scott Turner on UA-cam, great channel and he recently made a Brake too and ran into the same problems. Always interesting to watch everyone come up with their own solutions!
I’ve watched every video on building a brake. Yours is near the top! One thing I’ve seen in other videos is the ability to move the top piece forwards and backwards for different thickness metals any thoughts on that? I like your big tightening knobs do you get enough pressure on them, if not you could drill a few holes into the edge and put some longer bars in for leverage temporarily.
I actually haven't seen that, I'm guessing it's supposed to increase the bend radius? Honestly though, I doubt you'd be able to bend anything thicker than 2mm steel with a brake in this style anyway, unless you make it way, way beefier. As for the knobs, yeah they work great! Way more comfortable to use than wing nuts or a wrench. If your clamp bar is straight, you don't even need that much pressure. My problem before was that it would clamp on the sides but leave a gap in the middle.
Had pretty much same design for 15 years hard to improve on ,, mine has heavier truss not to deflect and sharp edge grind on bending edge will give you much better chrisp bends
First, love your videos man. You should try to custom build a titanium bike!
Ha, some day for sure! If I can ever afford it, and actually dare to weld it, Titanium is expensive as hell :) Awesome material though.
Really cool to watch. What cad program do you use for the catamaran?
Has everyone access to all the tools you used
I work night shift. We had a boss onsite. To wake my colleague up at his desk I played the first 20 seconds of this video as loud as it would go on a desktop PC speaker!!! HAHAHAHAH!
Glad I could help ;)
How thick sheet can you bend to 125cm?
С таким оборудованием такой примитивный листогиб сделать это надо ещё постараться)))
Love from Pakistan
Love you 😍
*To all those whining b/c he's using the machines he owns:* would it make you happy to see a machinist not use his own machines?
*You'd rather that they just sat there while he worked on projects that you get enjoy, and benefit from while watching?* smh...great video btw.
Bin ich der einzigste dem auffällt dass er einen schweren Konstruktionsfehler begangen hat und vergessen hat den biegeradius beim Hebel zu berücksichtigen? Denn der ändert sich ja bei jeder anderen Blechdicke
Mit einer Kantbank in dem Format kann man ohnehin nicht viel mehr als 2mm Bleche biegen, dafür müsste das Ganze noch wesentlich massiver sein. Und was anderes habe ich auch nicht vor, im Prinzip brauche ich das Teil nur für 1mm Alublech. In dem Bereich spielt das eigentlich nicht so eine große Rolle. Dafür dass die Konstruktion schwere Fehler hat funktioniert sie jedenfalls ganz gut ;)
beautifully made video with zero information for viewers..very well use of available tools
enjoy listening to your accent
It's both a brake it's a folder...))
👏👏👏👏👏👏👏👏👏👏👏👏👏👏
Sf300 mower
Truss should have been thicker not to deflect
Show how to make it without machine shop at your convenience. .unless ur making a government job at work
Даааа Ужжжж... Без фрезерного и токарного станков Такого не сделать Ни КогДа!!!!
As if everyone has a lathe and a milling machine
