Vise Tripod Lets You Put The Tool Where You Need It

October 17, 2021 by 7 Comments

Vises are useful things for holding whatever you’re working on, but too often they’re stuck to a bench. [seamster] has experienced the glory of having a more portable solution, however, and has shared his design for a heavy duty vise tripod that provides just that.

The trick is that to be useful, the design must be heavy and stout enough to hold the vise without tipping over. For this build, [seamster] selected a fat steel pipe with 1/4″ thick walls, some solid bars and some 3/8″ thick plate. Legs and arms where then fabbed up from the bar material and welded up to form the tripod. A stout plate for the vise was then welded on top of the pipe, and the vise mounted pride of place on top.

It’s not a particularly difficult build, but it’s a smart idea that gets you a vise you can easily drag to where it’s needed. If you don’t have the vise itself, consider this hydraulic build. Meanwhile, if you’ve been whipping up your own useful workshop hacks, let us know!

Machining Wood Inlays, No CNC Required

October 17, 2021 by 13 Comments

It’s almost hard to remember a time when the obvious answer to most questions about manufacturing wasn’t “Throw it on the CNC.” CNC machines have become so entrenched that the acronym has become a verb; few people would misunderstand a statement like “Let’s just CNC that.”

But before CNC machines became so ubiquitous, there were plenty of clever tricks for cutting material in a controlled fashion, as [Pask] shows us with this tool to machine wood for inlays. The tool is called a parser (or passer) drill, and is designed for use in conjunction with a steel template. [Pask]’s version seems pretty easy to make; a pair of mild steel bars are forged flat into spade shapes before having a cutting surface ground into them. The two halves of the drill are welded together and ground down to fit in the chuck of a hand drill, a modern nod to the fact that few people will want to use the traditional bow and breastplate that drove the original parser drills.

In use, a steel template that determines the shape of the inlay is affixed to the workpiece. The cutting edges of the bits are plunged into the template cutout to machine out the wood; the overhangs of the bits act as depth stop and guide. It only takes a few seconds to make a neat, CNC-free inlay. The video below shows the tool being made and in action.

It’s nice to see what can be accomplished without the need for fancy CNC machines. Not that we have anything against them, of course, but when the same results can be had with some scraps of steel and a little ingenuity, it’s pretty impressive. Looking for something between manual tools and CNC for woodworking? The pantorouter might be just your speed.

IBM Cheese Cutter Restoration

October 12, 2021 by 31 Comments

For a while now, Mac Pro towers have had the nickname “cheese grater” because of their superficial resemblance to this kitchen appliance. Apple has only been a company since the 70s, though, and is much newer than one of its historic rivals, IBM. In fact, IBM is old enough to have made actual cheese-related computers as far back as the 1910s, and [Hand Tool Rescue] recently obtained one of these antique machines for a complete restoration.

The tool arrived to the restoration workshop in a state so poor that it was difficult to tell what many of the parts on the machine did except for the large cleaver at the top. The build starts with a teardown to its individual parts, cleaning and restoring them to their original luster, machining new ones where needed, and then putting it all back together. The real mystery of this build was what the levers on the underside of the machine were supposed to do, but after the refurbishment it was discovered that these are the way that portions the cheese wheel would be accurately sized and priced before a cut was made.

By placing a section of a wheel of cheese on the machine and inputting its original weight with one of the levers, the second lever is adjusted to the weight of cheese that the customer requested, which rotates the wheel of cheese to the correct position before a cut is made. To us who are spoiled with a world full of electronic devices, a mechanical computer like this seems almost magical, especially with how accurate it is, but if your business in the 1910s involved cheese, this would have been quite normal. In fact, it would be 50 more years before IBM created the machines that they’re more commonly known for.

Handheld Bandsaw Gets Standup Conversion With Scrap Lumber

October 11, 2021 by 11 Comments

Handheld band saws exist, and can be highly useful tools. However, they lack some of the finesse and precision of the more traditional upright units, particularly for with smaller workpieces. [Honus] set about rectifying this, building a stand for their DeWalt handheld bandsaw out of scrap lumber.

The stand consists of some hefty wooden beams sawn to length and screwed together to make a support for the bandsaw. A nice 1/4″ thick aluminium plate is installed as a baseplate for cutting.

Then, the handheld bandsaw itself is attached to the rig, held in place with a bolt and a large zip tie. The zip tie is fastened around the trigger, holding it down all the time. Then, a switched powerboard is used to turn the saw on and off as needed. Importantly, simply cutting a ziptie and removing a bolt is enough to restore the handheld saw to its original purpose.

It’s a tidy build and one that makes an existing tool more useful for minimal extra cost. We’ve actually seen bandsaws built from scratch, too. If you’re cooking up your own great hacks in the home shop, be sure to let us know!

Building Your Own Filing Machine From A Kit

October 7, 2021 by 16 Comments

Files are a very useful important tool if you’re machining your own parts. They can do plenty of shaping themselves on smaller parts in particular. Powering such a tool just makes sense, and a die filer or filing machine is essentially just that, reciprocating a file up and down for you. They’re highly prized amongst clockmakers and model builders, and [jeanluc83] decided to build one at home.

The design chosen was the MLA-18 filing machine, for which castings and parts can be purchased from a company called Metal Lathe Accessories. However, it’s far from a simple screw-together kit. [jeanluc83] goes through the full process of painting, machining, and assembling the kit, which takes quite a bit of work to do properly.

Notably, the design is quite old fashioned in that it does not include its own power source. Instead, the MLA-18 filing machine is fitted with a pulley, such that it can be driven from a motor on a bench. A 1/4 horsepower motor running at roughly 1725 RPM is recommended for best results.

Filing machines aren’t exactly something you’ll find at every hardware store or Harbor Freight, so you might find building your own is the right way to go. Hackaday is, after all, full of examples of hackers building their own tools!

Cable Modem Turned Spectrum Analyzer

August 27, 2021 by 19 Comments

Hopefully by now most of us know better than to rent a modem from an internet service provider. Buying your own and using it is almost always an easy way to save some money, but even then these pieces of equipment won’t last forever. If you’re sitting on an older cable modem and thinking about tossing it in the garbage, there might be a way to repurpose it before it goes to the great workbench in the sky. [kc9umr] has a way of turning these devices into capable spectrum analyzers.

The spectrum analyzer feature is a crucial component of cable modems to help take advantage of the wide piece of spectrum that is available to them on the cable lines. With some of them it’s possible to access this feature directly by pointing a browser at it, but apparently some of them have a patch from the cable companies to limit access. By finding one that hasn’t had this patch applied it’s possible to access the spectrum analyzer, and once [kc9umr] attached some adapters and an antenna to his cable modem he was able to demonstrate it to great effect.

While it’s somewhat down to luck as to whether or not any given modem will grant access to this feature, for the ones that do it seems like a powerful and cheap tool. It’s agnostic to platform, so any computer on the network can access it easily, and compared to an RTL-SDR it has a wider range. There are some limitations, but for the price it can’t be beat which will cost under $50 in parts unless you happen to need two inputs like this analyzer .

Workshop Tools Are Available In First-Class

July 28, 2021 by 12 Comments

Most of dream of having a fully-stocked shop with all of the tools needed to build our projects, at least if we don’t already have such a shop. In the meantime, a lot of us are hacking together our own tools and working on whatever bench space might be available to us. While [Emiel] aka [The Practical Engineer] has an envious shop to work from, his latest project goes to show how repurposing some aircraft-grade equipment can result in a high-quality toolbox for himself, without shelling out for any consumer-level solution. (Video, embedded below.)

The core of his workshop cart build is actually a recycled food service cart from an airline. While the original probably only housed some soft drinks and ice, this one has been kitted out to be much more functional. Since [Emiel] is using this to wheel around his machine shop, he used a CNC machine to cut out slots in black MDF sheets which would hold his drill bits, taps, and other tools. Working with MDF on a CNC machine turned out to not be as simple as he thought, since the MDF would separate and break away unless the CNC tool heads were operated in a specific way.

The build also includes several buckets for other tools, and a custom enclosure for the top of the cart specifically built for his machine tools’ tools to sit while he is working. It’s certainly a more cost-effective solution to a wheeled shop toolbox than buying something off-the-shelf, and a clever repurposing of something which would have otherwise ended up in a landfill. [Emiel] is no stranger to building any tools that he might need, including this custom belt sander built completely from the ground up.
