Intro: Easy to Make and Use Vise Mounted Bending Tool.

Hi.

Every maker needs to bend metal sometimes. Usually those are small pieces, so it would feel somewhat wasting to build very big tool for that.

This is my solution for those needs. Its very simple, someone commented that its too simple, "obvious".

But he just didn't think of that, and that's the reason for this instructable.

Personally i think simpliest solutions are the best.

This version uses only one hinge, naturally result would be more sturdier with two.

But for the unexperienced welder, getting two hinges exactly to the same line, could be little difficult. ( little disortion and hinges would stuck )

This instructable doesn't include measures, because those varies too much between different sized vises.

But the idea is very simple, and easy to make.

All projects can be made better. Improvements can be seen from the last step.

I used my homemade vise. You can find instructable about it here.

Video shows the use. (don't let the music bother, i tought that video would little funnier with little overkill music)



Step 1: Bending Thicker Materials..

Bending thicker material requires bigger radius than thin materials. That's obvious.

If you try to bend steel with zero radius, bender turns to cutter.

That's why bender is installed 5mm higher than is the front jaw of the vise.

Rounding the edge of the jaw gives nicer result.

Step 2: Bending Thinner Materials..

Thinner materials can be bend with bigger radius too, but in case that i want smaller radius.

I have simple solution. I place piece of 3mm L-profile to the front jaw.

That gives smaller bending radius. Very simple solution.

Step 3: Materials..

Materials that i used.

80mm long weldable hinge. Costed 3€ at my local hw-store. ( price is for pair)

Piece of axle. Used 16mm, because it fitted to the handle that i made to my manual bar bender.

10mm steel plate. Cut to the same widht with my vise.

Hinges are installed so that the side of the bender wich points inside the vise, is same level.

Hinges are weld around, but the axle where handle connects. is weld on from the ends.

Those are the points where most stress comes when in use.

Welding sides of the axle would unnecessarily bend the sturcture, and possible bend hinge. And it doesn't work after that.

That's it. Simple but usefull tool to every garage or workshop.



Step 4: Improvements.

Version at the beginning of this instructable was the simple version, just one alternative to traditional "Hammering in the vise " - method.

To make bigger bends i use these diy tools. One, Two , Three.

Of course everything can be improved. And first improvement to this, was to make continuous bending radius adjustment. This makes bender more suitable for diffrent thicknesses.

Of course, possibility to lift other jaw 20mm higher, than other helps with other tasks too.

Like when filing thin objects, allows to lift the other jaw and also the workpiece higher to get better view for the line, is

one example.To clamp odd shaped objects.. etc.

Stronger bender, two hinges side by side. Little tricky to get them to the same line, but not difficult.


Video shows the making.

Step 5: Improvements Continued...

Simple improvement... allows to adjust the position of the point that leans against workpiece.

This gives more symmetrical result.

    Tip 7 months ago

    Good tip from the Steelsmith.


    I rather have many different jaws. Ones with the round grooves to be able to mount round objects, different kinds for vertical or horizontal mounting. Ones with right angled grooves, for the L- profile or square shape. This allows tight mounting without leaving marks.

    My jaws are mounted with three screws, so changing won't take long. That's why i think that vise should be made with removable jaws.
    .. So, all depends from the use and the user. That's why there's so many different vises, and ways to use them.

    Tip 7 months ago on Step 1

    Rather than rounding a jaw on a vice, make sheet metal inserts whee the metal is bent at how ever sharp the edge of the vise is. The thicker the sheet metal the larger the radius. 2 or 3 of these should suffice for most things and will leave your vice with it's original jaws. I dislike modifying things like vise jaws permanently when a simple insert will do the job, especially on a jig that is clamped in the vice only part of the time.

    That's a really good project.
    It's pretty simple, but anyone can make one and adapt from materials and tools that they already have.

    Congrats

    Genius idea! It really is almost too simple, and anyone with a vise could quickly have a simple and quickly made metal brake. I'm definitely making one soon!

    Thanks. I was thinking same too. "Its too simple". That's why i decided to make height adjustment to the front jaw. Then i could unportable adjust suitable thickness to different materials. I'll update this instructable within couple days...

    But, even with the thickness adjustment, this can easily be done with every vise that have removable jaws, its also little more versatile than other vise benders that i have seen.

    I think you are meaning "continuous" adjustment here? "Unportable" means something too heavy to carry.

    Yeah.. Thank you.

    Weird language.
    Continous ( never stop )
    Portable adjustment and Unportable adjustment sounds more obvious to me. :)

    Reason to use one hinge in this easy version was, that even unexperienced welder can get one hinge to somewhat right line. But when there's two of them side by side, its more difficult. Little disortion and hinges doesn't move.

    5mm alumine goes easily. With two hinges, it depends from used radius & power. With bigger radius its possible to bend thicker material wit less power.

    There's no tooths on the jaws and edge is rounded. This was easies possible version, for random users. I use this : https://www.instructables.com/id/Sheet-Metal-Plastics-Bending-Brake/

    by myself.

    Of course i made a radius adjustment to it, and will use two hinges also. As i mentioned, tried to keep this simple as possible, alternative to hammer & vise method.

    Picture from the radius adjustment.

    Hello! Great design! What is that kind of vise? I didn't know this model.

    Very worthwhile project if anyone ever wants to bend materials. Also very helpful when attempting to bend softer materials that need to be heated to be bent such as plastics. Or even for holding two pieces to be glued under pressure.

    Excellent!
