A Tube, The Wooden Kind

While we aren’t heavy-duty woodworkers, we occasionally make some sawdust as part of a project, and we admire people who know how to make wood and do what they want. We were surprised when [Newton Makes] showed a wooden dowel that was quite long and was mostly hollow. The wall was thin, the hole was perfectly centered, and he claimed he did not use a drill to produce it. Check it out in the video below and see what you think.

We don’t want to spoil the surprise, but we can tell you that making something that long with a drill or even a drill press would be very difficult. The problem is that drills have runout — the bits are usually not totally centered, so the bit doesn’t spin like you think it does. Instead, it spins and rotates around a small circle.

Cyberbass Brings Bass Guitar To Modern Era

For better or worse, the fundamental design of guitars has remained familiar since they electrified around a century ago. A few strings, a fretboard, and a body of some sort will get you most of the way there for an acoustic guitar, with the addition of electromagnetic pickups and wiring for electric variants. However, technology has advanced rapidly in the last 100 years outside the musical world, so if you want to see what possibilities lie ahead for modernizing guitars take a look at the Cyberbass created by [Matteo].

The guitar starts its life as many guitars do: with a block of wood. One of the design goals was to be able to use simple tools to build the guitar, so the shape of the instrument was honed with a Japanese hacksaw and the locations for the pickups and other electronics were carved out with chisels.

The neck of the guitar was outsourced since they take some pretty specialized tools to build, so simply bolting it to the body takes care of that part of the build, but [Matteo] had a few false starts setting the bridge in the exact location it needed to be.

Luckily he was able to repair the body and move the bridge. With the core of the guitar ready, it was on to paint and then to its custom electronics. [Matteo] built in not only a set of pickups and other common electric guitar parts but also integrated a synth pedal into the body as well as including a chromatic tuner.

With everything assembled and a few finishing touches added including a custom-engraved metal signature plate, the Cyberbass is ready to go on tour. [Matteo] learned a lot about guitar building in general, as well as a few things about electronics relating to musical instruments (including how expensive tuners work just as well as cheap ones).

Broken USB Lamp Saved With A Bit Of Woodworking

For many of us, when we think of creating a custom enclosure, our minds immediately go towards our 3D printer. A bit of time in your CAD program of choice, and in an hour (or several), you’ve got a bespoke plastic box. A hacker’s dream come true.

But extruded plastic is hardly perfect. For one thing, you might want a finished piece that looks a little more attractive on your desk. Which is why we appreciate this quick hack from [Tilma]. When faced with a broken LED light and minimal equipment, he decided to transplant the repaired electronics into a scratch-built wooden frame that not only looks better than the original, but is more functional.

A pair of hands hold two dark brown boards perpendicular two each other on a light brown benchtop. There are two light brown oval dowels in the end of one board that then project toward holes in the opposite board. Circular holes in the oval dowels are visible perpendicular to the second board, and will match up with holes in the board once pressed in. A cylindrical dowel is laying next to the joint and will be placed into the circular holes once assembled.

Creating A Signature Wood Joint

We really love when makers make their construction techniques evident in an aesthetically-pleasing way, and [Laura Kampf] has created a clever joint that reveals how a piece is made.

[Kampf] is a big fan of using her domino joiner, which is similar to biscuits or dowel joinery, but she didn’t love how it hid the construction of the joint. She first figured out an “off label” use of the joiner by running it from the outside of the joint to show the exposed domino from one end.

Building on the concept to show an interesting contrast on both sides of the joint, she drilled a hole perpendicular the domino and placed a dowel through it, creating a locking joint. The choice looks great once a finish is applied to really accentuate the contrast, and another bonus is that if glue is only applied to the dowel and domino, it becomes trivial to separate the joint if needed by drilling out the dowel.

If you’d like to see some other interesting ways to join wood, how about this laser-cut wedge tenon, soda bottle heat shrink, or this collection of CNC joints.

Bread Proofing Box For The Hungry Hacker

While normally more comfortable with a soldering iron, [LucidScience] recently took a dive into woodworking and hardware store electronics to build a DIY proofing box. It’s a clever design that doubles as furniture, with some cool problem-solving along the way. While it might not be your typical hack, repurposing seedling heat mats and working with insulation makes it a neat project for anyone who likes to tinker. Plus, the whole thing cranks out two loaves of sourdough bread each week!

The setup includes an 8 watt heat mat, typically used for aquariums or seedlings, and a temperature control box, so no complicated wiring is needed. The entire box is insulated with rigid foam, which makes it energy efficient—once the foam was installed, the heat mat only needed to turn on about a quarter of the time. To give it a more polished look, [LucidScience] hid the raw plywood edges with oak trim, and even added an adjustable vent for moisture control. Pretty slick for something built from basic materials and a few tools!

While this proofing box isn’t a groundbreaking electronics project, it shows how even simple hardware can be repurposed for entirely new applications. The combination of woodworking and basic electronics makes it an approachable project for DIYers looking to stretch their skills. Whether you’re into hacking, woodworking, or just love good bread, this build has something for everyone. [LucidScience]’s clear instructions and simple materials make this a great weekend project that can upgrade your baking game.

A DaVinci Screw-Cutting Machine

It’s not news that Leonardo DaVinci was somewhat ahead of his time, and over the centuries many of the creations in his sketchbooks have been created and proved quite functional. The guys from the YouTube channel How To Make Everything have been looking at one such sketch, a screw thread-cutting machine. At first glance, it seems a little flawed. Threads are hard to make by hand, and you can see that this thread-cutting machine needs two identical threads operating as a reference to make it work. However, as the guys demonstrate, you can create threads by hand using simple methods.

Starting with an offset blade mounted on a block with a hole through it, a dowel can be scribed with a starter thread. This can then be worked by hand to cut enough of a groove for the application. They demonstrated that the machine was viable using nothing but wood for construction. A metal blade was mounted, and some preload force was applied to it with a spring. The dowel to be cut was loaded, and the machine ran back and forth enough times to create a very nice-looking screw thread. And once you’ve made two identical threaded dowels, you can use them to upgrade the machine or even build a second. Once you have a repeatable way to make such threads, all kinds of applications become more accessible. Need a bench vice? No problem now!

Whilst the demonstration doesn’t precisely follow the plans laid out by the master inventor, they aren’t all that clear on the cutting tool after all, it’s nice to see people still wanting to build his ideas, and we’ll certainly be following along.

If you like these “from scratch” builds, you’ll like this other one. Leonardo’s work wasn’t just about machines; he was also very interested in science. Here’s a recreation of his demonstration of gravity as a form of acceleration.

Mobile Coffee Table Uses Legs To Get Around

For getting around on most surfaces, it’s hard to beat the utility of the wheel. Versatile, inexpensive, and able to be made from a wide array of materials has led to this being a cornerstone technology for the past ten thousand years or so. But with that much history it can seem a little bit played out. To change up the locomotion game, you might want to consider using robotic legs instead. That’s what [Giliam] designed into this mobile coffee table which uses custom linkages to move its legs and get itself from place to place around the living room.
