Dollar Store Helping Hands For Soldering

October 21, 2018 by Al Williams 20 Comments

Although [I Love To Make] appears to have text in Chinese, their recent video (see below) is like a wordless workshop so it won’t matter if you are up on your Mandarin or not. The soldering vise looks like it mostly came from a dollar store (or perhaps a yaun store).

As far as we can tell, the assembly is two utility clips like you might use on a cork board or to seal up chips, a Micro SIM cutter, and TV rabbit ears. Oh, and a syringe. The rabbit ears get mostly destroyed in the build process. You have to do some cutting and plastic melting, too (we might have used a drill), but nothing you couldn’t do with some simple hand tools. They don’t show it, but apparently, they drilled a hole in the SIM cutter, so you’ll need a drill anyway.

A Scratch-Built Drill Press Vise From Scrap

August 29, 2018 by Dan Maloney 12 Comments

Never underestimate the importance of fixturing when you’re machining parts. No matter what the material, firmly locking it down is the key to good results, and may be the difference between a pleasant afternoon in the shop and a day in the Emergency Room. Flying parts and shattered tooling are no joke, but a lot of times quality commercial solutions are expensive and, well, commercial. So this scratch-built drill press vise is something the thrifty metalworker may want to consider.

To be sure, [Ollari’s] vise, made as it is almost completely from scrap angle iron, is no substitute for a vise made from precision ground castings. But it’s clear that he has taken great care to keep everything as square and true as possible, and we give him full marks for maximizing his materials. And his tools — nothing more complicated than a MIG welder is used, and most of the fabrication is accomplished with simple hand tools. We like the way he built up sturdy profiles by welding strap stock across the legs of the angle iron used for the jaws, to give them a strong triangular cross-section to handle the clamping force. And using the knurled end of an old socket wrench as the handle was inspired; we’ll certainly be filing that idea away for a rainy day in the shop. Although we might use Acme rather than plain threaded rod.

We always enjoy seeing someone fabricate their own tools, and this one reminds us a bit of the full-size bench vise built up from layers of welded steel we featured a while back. It even looks a little like this 3D-printed vise, too.

Leather Working With A 3D Printer

August 14, 2018 by Al Williams 22 Comments

No, you can’t print in leather — at least not yet. But [Make Everything] has a tutorial about how to produce a custom leather embossing jig with a 3D printer. From a 3D printing point of view, this isn’t very hard to do and you might want to skip over the first six minutes of the video if you’ve done 3D printing before.

The real action is when he has the 3D print completed. He glues the stamp down to some wood and then fits the assembly to a vise that he’ll use as a press. After wetting the leather, the wood and 3D printed assembly sandwiches the piece and the vise applies pressure for ten minutes. He did make the leather a bit oversized to make alignment more forgiving. After the embossing is complete, he trims it out.

Universal Quick-Release Bar Clamps

April 30, 2018 by Anool Mahidharia 8 Comments

The typical hacker can never say no to more tools. And when it comes to clamps, one just can’t have enough of them. From holding small PCB’s to clamping together large sheets of plywood, you need a variety of sizes and quantities. So it would be pretty neat if we could just 3D print them whenever needed. [Mgx3d] has done that by designing 3D printable bar clamp jaws with a quick release mechanism that can be used with standard T-slot aluminum extrusion. This allows you to create ad-hoc bar clamps of any size and length quickly.

The design consists of two pieces – the jaw and its quick release lever, and does not require any additional parts or fasteners for assembly. Both pieces can be easily 3D printed without supports. The quick release lever is a simple eccentric cam design which locks the jaw in place by pushing down on the extrusion. The design is parametric and can be easily customized for different sizes, either in OpenSCAD or via the online customizer. The online customizer supports Misumi 15 mm and 20 mm extrusion, 1″ 1010-S and 20 mm 20-2020 from 80/20 Inc., 15 mm from OpenBeam and 10 mm from MicroRax. But it ought to be easy to create fresh designs in OpenSCAD. Check out the video after the break to see the bar-clamps in action.

If you’d like to start equipping your shop with more 3D printed tools, look no further. We’ve featured many types over the years, such as the StickVise and its Gooseneck System, this 3D printed rubber band PCB Vise, and even a 3D printed Mini-Lathe.

Your Work Won’t Move With A Magnetic Drill Press Vise

September 8, 2017 by Dan Maloney 32 Comments

Setting up your workpiece is often the hardest part of any machining operation. The goal is to secure the workpiece so it can’t move during machining in such a way that nothing gets in the way of the tooling. Magnetic chucks are a great choice for securely and flexibly holding down workpieces, as this simple shop-built electromagnetic vise shows.

It looks like [Make It Extreme] learned a thing or two about converting microwave oven transformers to electromagnets when they built a material handling crane for the shop. Their magnetic vise, designed for a drill press but probably a great choice for securing work to a milling machine, grinder, or even a CNC router, has a simple but sturdy steel frame. Two separate platforms slide on the bed of the vise, each containing two decapitated MOTs. Wired to mains power separately for selective control and potted in epoxy, the magnets really seem to do the job. The video below shows a very thick piece of steel plate cantilevered out over one magnet while having a hole cut; that’s a lot of down force, but the workpiece doesn’t move.

Like the idea of a shop-made vise but would rather go the old-fashioned way? Check out [Make It Extreme]’s laminated bench vise, which also makes an appearance in this video.

Need To Hold Something? Build A Custom Vise

June 15, 2017 by John Baichtal 15 Comments

The only thing better than making a cool project is making a cool project that helps make more projects! Case in point, [Greg Stephens] and [Alex] wanted to colorize steel bearings for use in a Newton’s Cradle desk toy. After trying out a torch and not liking it, [Greg] and [Alex] decided to build custom aluminum vise to hold the sphere while it sits in the magnetic induction forge.

Their vise–they call it the Maker’s Vise0–isn’t just a one-off project to help make the cradle. [Alex] and [Greg] aspire to create a tool useable for a wide variety of projects. They wanted it to be oil-less and it had to be customizable. Ideally it would also have an acceptable grip strength, be easy to use, and look good on the bench.

[Greg] and [Alex] have set up a Hackaday.io project, and their logs show a lot of progress with two finished iterations of the vise and a variety of 3D-printed and cast parts to go with. Recently they brought in a 2,000-lb. load test and tested it on their vise collection, including the two prototypes. Version one rated at 500 lbs. reasonable clamping pressure–meaning they didn’t exert themselves to max out the pressure. Version two sits at 800 lbs., still nothing like a desk vise but far stronger than a Panavise, for instance.

Their magnetic induction forge project was also a success, with the team able to quickly change the color of a steel ball. Check out a video after the break…

Cheap Helping Hands: Just Add Time

May 12, 2017 by Al Williams 34 Comments

We think of helping hands as those little alligator clips on a metal stand. They are cheap and fall over, so we tend to buy them and don’t use them. However, if you are willing to put $35 or $40 into it, you can get the newer kind that have–well–tentacles–on a heavy base. [Archie_slap] didn’t want that kind of investment, so he made his own for about $10. We think that’s Australian dollars, so that’s even less in the United States.

What’s better is he documented every step in meticulous detail and with great pictures. You probably won’t directly duplicate his project because you will probably pick up a slightly different base, but that’s not hard to figure out. The arms are actually coolant hose, [Archie_slap] picked up almost everything but the base plate on eBay.

It’s obvious [Archie] is a frugal guy, based on his drill press. It gets the job done, though. The build is attractive and looks like a much more expensive commercial product. Some of us around the Hackaday lab are old enough to wish there was a magnifying glass attached, but maybe that’s version two.

We’ve looked at a lot of different helpers recently. We couldn’t help but think about a somewhat similar Gorillapod holder we covered last year.
