Custom Pneumatic Cylinders Lock This Monitor Arm In Place

Few consumer-grade PCs are what you’d categorize as built to last. Most office-grade machines are as likely as not to give up the ghost after ingesting a few too many dust bunnies, and the average laptop can barely handle a few drops of latte and some muffin crumbs before croaking. Sticking a machine like that in the shop, especially a metal shop, is pretty much a death sentence.

And yet, computers are so useful in the shop that [Lucas] from “Cranktown City” built this neat industrial-strength monitor arm. His design will look familiar to anyone with a swing-arm mic or desk light, although his home-brew parallelogram arm is far sturdier thanks to the weight of the monitor and sheet-metal enclosure it supports. All that weight exceeded the ability of the springs [Lucas] had on hand, which led to the most interesting aspect of the build — a pair of pneumatic locks. These were turned from a scrap of aluminum rod and an old flange-head bolt; when air pressure is applied, the bolt is drawn into the cylinder, which locks the arm in place. To make it easy to unlock the arm, a pneumatic solenoid releases the pressure on the system at the touch of a button. The video below has a full explanation and demonstration.

While we love the idea, there are a few potential problems with the design. The first is that this isn’t a fail-safe design, since pressure is needed to keep the arm locked. That means if the air pressure drops the arm could unlock, letting gravity do a number on your nice monitor. Second is the more serious problem [Lucas] alluded to when he mentioned not wanting to be in the line of fire of those locks should something fail and the piston comes flying out under pressure. That could be fixed with a slight design change to retain the piston in the event of a catastrophic failure.

Problems aside, this was a great build, and we always love [Lucas]’ seat-of-the-pants engineering and his obvious gift for fabrication, of which his wall-mount plasma cutter is a perfect example.

Thrift Store CD Rack Turns Into Small Parts Storage Playground

What in the world could an accessory for an obsolete audio medium possibly have to do with keeping all your unruly bits and pieces in order? First of all, we’re not sure the CD is quite dead yet; we’ve got about a thousand of them packed away somewhere, and we’re pretty sure they’ll be back in style again one of these days. Until then, though, the lowly CD rack might be just what you need to get your shop under control.

As [Chris Borge] relates the story, he stumbled over this CD rack at a thrift sale and quickly realized its potential. All it took was some quick design work and a bit of 3D printing. Okay, a lot of 3D printing, including some large, flat expanses for the drawer bottoms, which can be a problem to print reliably. His solution was simple but clever: pause the print and insert a piece of stiff card stock to act as the drawer bottom before continuing to print the sides. This worked well but presented an adhesion problem later when he tried to print some drawer dividers, so those were printed as a separate job and inserted later.

Sadly, [Chris] notes that the CD format is not quite Gridfinity compatible, but that’s not a deal breaker. He also doesn’t provide any build files, but none are really necessary. Once you’ve got the basic footprint, what you do with your drawers is largely dependent on what you’ve got to store. The video below has a lot of ideas for what’s possible, but honestly, we’re looking at all those little parts assortment kits from Bojack and Hilitchi piled up in a drawer and just dreaming about the possibilities here. Add a voice-activated, LED inventory locator, and you’d really have something. Off to the thrift store!

No Tool Left Behind With The Help Of Homemade Shadow Boards

Shadowed tool storage — where a tool outline shows at a glance what’s missing from storage — is a really smart way to keep your shop neat. They’re also super important for cases where a tool left behind could be a tragedy. Think, where’s-that-10-mm-socket-while-working-on-a-jet-engine? important. (It’s always the 10-mm socket.)

But just because shadow boards are smart, doesn’t mean they’re easy to make. That’s why [Scott Prince] came up with this semi-automated method for making toolbox shadow boards. The job of tracing around each tool on some sort of suitable material and cutting out the shapes seems straightforward, but the trick comes in organizing the outlines given the space available and the particular collection of tools.

[Scott]’s method starts with capturing images of each individual tool. He used a PiCam and a lightbox housed, strangely enough, in a storage bench; we’d love to hear the full story behind that, but pretty much any digital camera would do for the job. After compensating for distortion with OpenCV, cropping the images, and turning the image into a vector outline of the tool, [Scott] was left with the task of putting the tools into logical groups and laying them out sensibly. After tweaking the tool outlines and adding finger cutouts for easy pickup, [Scott] put his CNC router to work. He chose to use a high-density polyethylene product made by his employer, which looks fantastic, but MDF would work fine too.

We have to admit to a fair degree of toolbox envy now that we’ve seen what shadow boards can do. We’re a bit torn, though — [Zach Friedman]’s Gridfinity storage system has a lot going for it, too.

A French Cleat Twist On Electronics Bench Organization

For some of us, our workbench is where organization goes to die. Getting ready to tackle a new project means sweeping away a pile of old projects, exposing exactly as much bench space needed to plop down the new parts. On the other end of the spectrum lie those for whom organization isn’t a means to an end, but an end itself. Their benches are spotless, ready to take on a new project at a moment’s notice.

[Eric Gunnerson]’s new French-cleat electronics bench is somewhere in between those two extremes, although nowhere near as over-organized as the woodworking organizer that inspired it. If you’ve never heard of a French cleat, Google around a bit and you’ll see some amazing shops where the system of wall-mounted, mitered cleats with mating parts on everything from shelves to cabinets are put to great use. A properly built French cleat can support tremendous loads; [Eric]’s system is scaled down a bit in deference to the lighter loads typically found in the electronics shop. His cleats are 2″ x 3″ pieces of pine, attached to a sheet of plywood that was then screwed to the wall. His first pass at fixtures for the cleats used a Shaper Origin CNC router, but when that proved to be slow he turned to laser-cut plywood. The summary video below shows a few of the fixtures he’s come up with so far; we particularly like the oscilloscope caddy, and the cable hangers are a neat trick too.

What we like about this is the flexibility it offers, since you can change things around as workflows develop or new instruments get added. Chalk one up for [Eric] for organization without overcomplication.

The Book Of Dreams Brings Back All Your Memories

The retro-facing side of British social media has been abuzz for the last few days with a very neat piece of marketing form the catalogue retailer Argos: they’ve digitised all their catalogues since 1975 and put them online. While this contains a cross-section of over four decades’ styles, fads, and ephemera, it also gives the browser a fascinating look at a host of retrotechnology from a contemporary viewpoint rather than through the rose-tinted glasses of 2019. It may not be a hack, but we guarantee you’ll spend a while browsing it!

Tiny Woodshop Is Packed With Space-Saving Hacks

Fair warning: once you’ve watched [Stephen]’s tiny workshop tour, you will officially be out of excuses for why you need to expand your workshop. And, once you see his storage and organization hacks, you’ll be shamed into replicating some in whatever space you call home.

[Stephen]’s woodshop is a cozy 6′ x 8′ (1.8 m x 2.4 m) garden shed. The front wall is almost entirely occupied by the door and a window, reducing the amount of wall space available but providing ample natural light and keeping the small space from inducing claustrophobia. Absolutely every square inch of the remaining space is optimized and organized. [Stephen] wisely eschews bulky cabinets in favor of hanging tool racks, all mounted flexibly to the wall on French cleats. Everything has a place, and since every hand tool is literally within arm’s reach, it stays stored until it’s needed and goes right back when it’s done. The shop boasts way more than hand tools, though; a lathe, drill press, thickness planer, sander, air compressor, scroll saw, band saw, and even a table saw all fit in there. There’s even dust collection courtesy of “The Beast”, [Stephen]’s DIY dust extractor.

No matter whether you work in wood, metal, or silicon, we could all learn some lessons fromĀ [Stephen]’s shop. It’s a model of efficiency and organization, and while he’s not likely to build a full-size [Queen Anne] dresser in there, it’s clear from his blog that he gets a lot done with it. Too bad we missed this one the last time we did a roundup of tiny shops.

Pop-Up Outlet Helps Make The Most Of A Tiny Shop

You’ve got to admire the steps some people take to squeeze a shop into a small space. Finding ways to pack in ever more tools and to work on bigger and bigger projects become ends to themselves for some, and the neat little tricks they find to do so can be really instructive.

Take this workbench pop-up outlet strip for example. The shop that [Woodshop Junkies] occupies appears to be a single-car garage, on the smallish size in the first place, that is almost entirely filled with a multipurpose workbench. It provides tons of storage underneath and a massive work surface on top, but working with small power tools means stretching extension cords across the already limited floor space and creating a tripping hazard. So he claimed a little space on the benchtop for a clever trap door concealing a small tray holding an outlet strip.

The tray rides on short drawer glides and, thanks to a small pneumatic spring, pops up when the door is unlatched. There was a little trouble with some slop in the glides causing the tray to jam, but that was taken care of with a simple roller bearing. The video below shows its construction and how it stays entirely out of the way until needed.

As cool as this build is, it’s just icing on the small shop cake when compared to the workbench. [Woodshop Junkies] has a complete playlist covering the build which is worth watching. And you might want to refer to our tiny shop roundup for more tips on getting a lot done in a little space.
