Single Bolt Transformed Into A Work Of Art

Every once in a while, this job helps you to discover something new and completely fascinating that has little to do with hacking but is worth sharing nonetheless. Turning a single brass bolt into a beautiful Cupid’s bow is certainly one of those times.

Watching [Pablo Cimadevila] work in the video below is a real treat, on par with a Clickspring build for craftsmanship and production values. His goal is to use a largish brass bolt as the sole source of material for a charming little objet d’art, which he achieves mainly with the use of simple hand tools. The stave of the bow is cut from the flattened shank of the bolt with a jeweler’s saw, with the bolt head left as a display stand. The offcuts are melted down and drawn out into wire for both the bowstring and the shaft of the arrow, a process that’s fascinating in its own right. The heart-shaped arrowhead and the faces of the bolt head are bedazzled with rubies; the technique [Pablo] uses to create settings for the stones is worth the price of admission alone. The complete video below is well worth a watch, but if you don’t have the twelve minutes to spare, a condensed GIF is available.

[Pablo]’s artistry reminds us a bit of this not-quite-one-bolt combination lock. We love the constraint of sourcing all a project’s materials from a single object, and we really appreciate the craftsmanship that goes into builds like these.

Making A Bronze Cannon From Scratch

Casting metal at home is somewhat tricky, but there’s no denying the results can be quite rewarding. [FarmCraft101] put his incredible craftsmanship on display, and learned a few new things in the process, by scratch building a scale replica bronze cannon and carriage.

Starting with a sufficient quantity of scrap metal, he first produced bronze ingots. Getting the actual casting right took multiples attempts. First tried a lost foam cast, which failed miserably, but provided a sample metal which was put through tensile strength testing. The second attempt was done using a wood barrel form and a split mold, and was cast horizontally which resulted in shrinkage on top of the barrel. The third attempt, arranged vertically, almost resulted in a high risk game of “the floor is lava”, with molten bronze pouring out across his garage floor after the mold split open during casting.

Attempt number four was finally successful, again using a vertical mold but with more sturdy clamping. This roughcast barrel was then drilled out and finished to a beautiful mirror with the help of a lathe and a lot of elbow grease. He then turned his attention to the carriage, which itself is a real beauty featuring custom wagon wheels with a charred wood finish and linseed oil coating.

You can check out the build video after the break, but we’ll warn you now, [FarmCraft101] never actually fires this gorgeous creation. If you’d like to try your hand at DIY cannoneering and have a 3D printer, you might want to give lost PLA casting a try, or go into mass production with some DIY silicone molds.

Exquisite Craftsmanship Elevate Vic’s Creations Above The Rest

This booth was easy to miss at Maker Faire Bay Area 2019 amidst tall professional conference signage erected by adjacent exhibitors. It showcased the work of [Dr. Victor Chaney] who enjoys his day job as a dentist and thus feels no desire to commercialize his inventions — he’s building fun projects for the sake of personal enjoyment which he simply calls Vic’s Creations. Each project is built to his own standards, which are evidently quite high judging by the perfect glossy finish on every custom wood enclosure.

Some of these creations were aligned with his musical interests. The Backpacking Banjo was built around a (well cleaned) cat food can to satisfy the desire for a lightweight instrument he can take camping. His Musical Laser Rainbow Machine (fully documented in Nuts & Volts) was created so little bands formed by independent artists like himself can have a visual light show to go with their live performances. The Music Kaleidoscope is another execution along similar lines, with an LED array whose colors are dictated by music. Venturing outside the world of music, we see a magnetically levitated Castle In The Clouds which also receives power wirelessly to illuminate LEDs

The largest and most complex work on display is an epic electromechanical masterpiece. Par One is a rolling ball sculpture featuring the most convoluted golf course ever. Several more rolling ball sculptures (also called marble machines or marble runs) are on display at Dr. Chaney’s office which must make it the coolest dentist’s lobby ever. The lifelike motions he was able to get from the automatons he built into the sculpture are breathtaking, as you can see below.

“Attempt” At Wristwatch Is A Solid Success

Sometimes silence is the best compliment to a DIY project, and that doesn’t just apply to homemade lockjaw toffee. When a watch is so well-made that it looks like one from a jewelry store, it is easy to keep quiet. [ColinMerkel] took many pictures of his fourth wristwatch attempt but “attempt” is his word because we call this a success. This time around he didn’t forget the crown for adjusting the time so all the pieces were in place.

His second “attempt” at wristwatch making was featured here and it had a classical elegance. Here, the proverbial game has been stepped up. Instead of using stock steel, the body is constructed of 303 stainless steel. The watch dial will definitely draw compliments if its DIY nature is revealed, which is equally mathematical and charming. Pictures of this process were enough to convey the build without words which is always a bonus if you only want a quick look or English isn’t your first choice for language.

Not only is [Colin] an upstanding horologist, he has a reputation with aftermarket door security and a looping guitar pedal.

A Micro RC Plane Builder Shares His Tricks

There are individuals who push tools, materials, and craftsmanship to the limit in the world of micro RC aircraft, and [Martin Newell] gives some insight into the kind of work that goes into making something like a 1:96 scale P-51 Mustang from scratch. The tiny plane is 100% flyable. It even includes working navigation lights and flashing cannons (both done with 0402 LEDs) and functional, retractable landing gear. It weighs an incredible 2.9 grams. Apart from the battery, everything in the plane was built or assembled from scratch. A video is embedded below.

Electronic Message In A Bottle

We remember going to grandfather’s garage. There he would be, his tobacco pipe clenched between his teeth, wisps of smoke trailing into the air around him as he focused, bent over another of his creations. Inside of a simple glass bottle was something impossible. Carefully, ever so carefully, he would use his custom tools to twist wire. He would carefully place each lead. Eventually when the time was right he would solder. Finally he’d place it on the shelf next to the others, an LED matrix in a bottle.

led-message-in-a-bottle-assemblyWell, maybe not, but [Mariko Kosaka]’s father [Kimio Kosaka] has done it. In order to build the matrix, he needed tools that could reach inside the mouth of the bottle without taking up too much space to allow for precise movement. To do this he bent, brazed, twisted, and filed piano wire into tools that are quite beautiful by themselves. These were used to carefully bend and position the LEDs, wires, and other components inside the bottle.

Once the part was ready, he used a modified Hakko soldering iron to do the final combination. We wonder if he even had to be careful to solder quickly so as not to build up a residue on the inside of the bottle? The electronics are all contained inside the bottle. One of the bottles contained another impressive creation of his: an entire Arduino with only wire, dubbed the Arduino Skeleton. Batteries are attached to the cork so when the power runs low it can be removed and replaced without disturbing the creation.

It’s a ridiculous labor of love, and naturally, we love it. There’s a video of it in operation as well as one with him showing how it was done which is visible after the break. He showed them off at the Tokyo Maker Faire where they were surely a hit.

Feel Extreme Workbench Envy After Seeing The Tempel

For those of us with space to spare, our workbenches tend to sprawl. The others who are more space limited will certainly feel envy at [Love Hultén]’s beautiful Tempel workbench.

The workbench appears at first to be a modern interpretation of a secretary’s desk. There are some subtle hints that it is no ordinary piece of furniture. The glowing model of our solar system on the front, for example.

With the front folded down, rather than the expected leather writing pad and letter sized drawers, a few more oddities become apparent. The back is a pegboard which holds a small selection of tools. To the left, a checkered grid obscures speakers. Knobs control volume There are even USB ports. On the right sits another speaker. Banana jacks let you use the analog voltmeter. Most appealingly, the indestructible Hakko 936 soldering iron has been entirely integrated into the structure of the desk.

If you press the right button on the front, the desk will reveal its last secret. It contains an entire workstation somewhere behind the array of drawers on the front. A linear actuator pushes a computer monitor up from inside the cabinet, covering the pegboard in the back. Awesome.

There is a build log, but unfortunately it’s been imageshacked and only the words remain. We think [Love Hultén] has finally managed to build a soldering station that’s welcome in every room of the house except for the garage.
