3D-Printed Tools Turn Bench Vise Into Expedient Press Brake

Chances are pretty good that most of us have used a bench vise to do things far beyond its intended use. That’s understandable, as the vise may be the most powerful hand tool in many shops, capable of exerting tons of pressure with the twist of your wrist. Not taking advantage of that power wouldn’t make any sense, would it?

Still, the clamping power of the vise could sometimes use a little finesse, which is the thinking behind these 3D-printed press brake tools.  [Brauns CNC] came up with these tools, which consist of a punch and a die with mating profiles. Mounted to the jaws of the vise with magnetic flanges, the punch is driven into the die using the vise, forming neat bends in the metal. [Braun] goes into useful detail on punch geometry and managing springback of the workpiece, and handling workpieces wider than the vise jaws. The tools are printed in standard PLA or PETG and are plenty strong, although he does mention using his steel-reinforced 3D-printing method for gooseneck punches and other tools that might need reinforcement. We’d imagine carbon-fiber reinforced filament would add to the strength as well.

To be sure, no matter what tooling you throw at it, a bench vise is a poor substitute for a real press brake. Such machine tools are capable of working sheet metal and other stock into intricate shapes with as few setups as possible, and bring a level of power and precision that can’t be matched by an improvised setup. But the ability to make small bends in lighter materials with homemade tooling and elbow grease is a powerful tool in itself.

Hydraulic Bench Vise A Masterpiece Of Scrap Metal And Angle Grinding

For most of us, a vise is the sort of thing you clamp onto the edge of a workbench and crank down by hand. It might even be made of plastic, depending on the kind of work you find yourself doing with it. But it’s safe to say that [WorkshopFromScratch] won’t be soldering any PCBs in the jaws of this nearly 100 lb hydraulic vise that he built from, well… scratch.

In the video after the break, he takes an array of scrap metal including what appears to be a chunk of racking from the Home Depot and a rusted plate that looks like it could be peeled off the hull of a sunken ship, and turns it into a monsterous vise with five tons of clamping force. Outside of a handful of bolts, a couple of gas struts, and the hydraulic bottle jack that that provides the muscle, everything is hand-cut and welded together. No fancy machining here; if you’ve got an angle grinder, a welder, and of course the aforementioned stock of scrap metal, you’ve got the makings of your own mega vise.

The piece of racking is cut down the center to form the base of the vise, but most everything else is formed from individual shapes cut out of the plate and welded together. Considering the piecemeal construction methods, the final result looks very professional. The trick is to grind all the surfaces, including the welds, down until everything looks consistent. Then follow that with a coat of primer and then your finish color.

While the whole build is very impressive, our favorite part has to be the hand-cut cross hatching on the jaws. With the workpiece in one hand and angle grinder in the other, he cuts the pattern out with an accuracy that almost looks mechanical. If we didn’t know better, we might think [WorkshopFromScratch] was some kind of metalworking android from the future.

Being able to work with metal is a fantastic skill to have, and we’re always impressed to see what folks can produce with a welder and some scrapyard finds. Especially when they build tools and equipment that can be put to practical use.

Cable Vise

New Cable-Based Vise Improves Woodworking Workshop

We are all aware of the typical wood shop vice, the type that is mounted underneath the workbench and takes forever to open and close by continuously spinning a large handle. These vises normally only open several inches due to the length of the operating screw. They are also not very wide because a cantilevered wide jaw would provide less force the further away it is from the center-mounted operating screw.

Cable ViseWood worker [Andrew] wanted a very versatile and large vise for his shop. It needed to be wide, provide equal clamping force along the jaw and be able to hold very thick objects as well. One more thing, he wanted it to have a quick release clamping system so there would be none of that continuous handle spinning nonsense.

Spoiler Alert: [Andrew] did it! The end product is great but the interesting part is the journey he had taken along the way. There were 4 revisions to the design, each one making the vise just a bit better.
