Introduction: Simple Vise Modifications to Bend Metals
This is my instructable about simple modifications to vise, to make tidy bends to metals.
There is multiple methods and attachments for different bending tasks, i wanted to find a solution that uses mostly actual vise itself.
I have been building a new kind of vise, these modifications are kind of prototypes that i wanted to test before actual building. Decided to share these first, because its obvious that everyone doesn't want to build the whole vise by them self.
I used my diy vise as a base, but these can be used with commercial vises too.
If you are interested to know more about my diy vise:
Here is a video about making it:
Step 1: Jaws..
First step is very simple, if you have little experience with metal working.
I made a pair of new jaws to my vise from 10mm thick steel plate, and 3mm x 20mm flat bar.
Weld flat bar to the edge of 10mm plate, and then rounded and smoothed the edge.
Measured the location of the jaw mounting holes from the vise, and copied them to the jaws.
After that i cut front jaw to three equal pieces, and back jaw to two pieces, one is 1/3 and second 2/3.
Then i got three different sized jaws that i could mix together for different bending / stamping options.
Step 2: Stamping Shapes..
Make different "stamps" i removed, or relocated jaw pieces.
You can see it from this video:
I think it explains it better than i can write.
Step 3: Making Bends..
Idea about making bends is very simple.
This method doesn't actually need new jaws at all.
If you have a vise with un-removable jaws, you can just cut/grind a V-groove to it and use it to make small bends.
Also, that groove are very handy when you need to clamp round or square pieces.
Max width of the bend depends the size of the jaw piece, ones that i made allows me to bend 40mm wide pieces.
Because i made front jaws narrower than back jaw pieces, i can adjust the width of the "die groove", simply
replacing one piece from the end to back. Wider cap allows to bend thicker materials.
Note: "tommy bar" on my vise is 15cm long ( about 6" ) i used pipe as a extension on the video.
That's aluminium pipe with a very thin wall, so it doesn't require much power, that pipe would have bent otherwise.
As a "front die" i used suitable sized pieces of pipe, personally i think that this is very usefull for bending small parts, those are really tricky to bend with tools that are made for big tasks.
Step 4: Rod / Bar Bender..
To get more use from my vise..
I made this simple rod / bar bending add to it.
I cut two pieces from the 10mm plate and weld them and a piece of 10mm rod to the wider back jaw.
After welding i filed a groove on the middle of it, this groove guides rods to the straight line with the bender.
Step 5: Bending Arm..
Bending arm is made from 40mm x 40mm x 4mm square tubing.
I drilled two holes trough it with 10mm drill, these holes are for the " bending facers ". ( leans to the rod to be bend)
Step 6: Arm Continued..
After drilling i made necessary cuts with angle grinder and 1mm cut of wheel.
( note, all 1mm cut of wheels doesn't perform very well with material this thick )
Personally i recommend 3M cubitron cut off wheels, or using thicker ones from some other brand.
After cutting i weld plug to the end and cut it to the right widht. ( seen on pictures or better on the video below )
First bending facer on the front is just a 10mm bolt. This one is used with thinner materials, and it gives little smaller bending radius.
Other one is located 40mm behind it and includes two bearings, this one is used with thicker materials, and it gives little bigger bending radius.
Video about making and using:
It also includes comparison about making bends on vise with " hands ".
Step 7: And.. the End of This Instructable.
And there it is.
This idea can be used with bought vises too.
And if you interested about the " ultimate vise " build, that i mentioned on first step.
Happy making, i hope you found something useful from this.

Ps. Here is a video about my angle grinder mount, that was also kind of prototyping for the final vise build.
