Detoured: Inside MachineHistories

March 7, 2018 by Brian Benchoff 18 Comments

When designers and architects need a fancy centerpiece, a design element, or even some wall sconces, they don’t head over to the machine shop by themselves. They get someone else, who owns some fancy machines, knows how to use those fancy machines, and can create anything out of wood, foam, or metal to do the fabrication for them. Think of these companies as artisan contractors, capable of turning whatever an architect thinks of into a real, tangible object.

One of these such companies is MachineHistories, a joint venture between [Steven Joyner] and [Jason Pilarsky], who work in the medium of computer code and CNC programming. As part of the SupplyFrame Design Lab’s Detoured series, lead Staff Designer [Majenta Strongheart] takes us along for a tour of MachineHistories to figure out how this collaboration actually works.

This collaboration began at the ArtCenter College of Design where [Steven] and [Jason] spent most of their time working in the shop. Eventually, they realized they didn’t actually need the ArtCenter and decided to sign a lease and strike out on their own. The first tools in their new shop were just a 3-axis CNC and a laser cutter, but MachineHistories gradually expanded to enormous five-axis machines and other incredible tools. These machines are put to work creating works of art for architectural and design installations, ranging from futuristic chairs, fine furniture, to sculptures and even new designs for simple home items.

The skill and craftsmanship that goes into these works of art are beyond compare, but this is a great insight into how all those manufactured panels, design elements, and artistic accents are created, and one that shows you can do anything, provided you have the right tools.

Detoured: Fabbing At The Art Institute Of Chicago

February 28, 2018 by Brian Benchoff 11 Comments

[Majenta Strongheart] is one of the talented folks who works at the SupplyFrame Design Lab, home to dozens of Hackaday meetups, the Hackaday Superconference, and when the shop floor isn’t filled with chairs, is the place where tons of awesome projects are fabricated. [Majenta]’s role at the Design Lab is a Staff Designer, where she’s responsible for working the machines, and holds the distinction of being in the room when the SawStop kicked for the first time. Don’t fret: it was mirrored acrylic.

Among [Majenta]’s other duties at the Design Lab is on the social media front, showing off the capabilities of other design spaces around the country. Her first video in this series is from her alma mater, the Art Institute of Chicago. In this video, [Majenta] takes a look at the incredible fabrication facilities found here.

The tour begins in an exceptionally well-equipped wood shop kitted out with panel saws, spindle sanders, bandsaws, and not enough clamps. From there, the tour moves over to the metal shop and — unique for the city of Chicago — a forge. A long time ago, after Philadelphia and New York were the tech centers of America, and before the Bay Area was the tech center of America, Chicago made everything. The forge at the Art Institute of Chicago is the last remaining place in the city where metal casting takes place. This space was grandfathered in, and still remains a place where students can cast objects out of bronze and aluminum.

The Art Institute of Chicago is a very, very well equipped space full of enough tools to make anything you want. If you’re looking for some inspiration on what your basement, garage, or local hackerspace should look like, you need only look at [Majenta]’s tour. You can check out the entire video below.

Making A Gun Without A 3D Printer

September 22, 2017 by Bryan Cockfield 120 Comments

Around four years ago the world was up in arms over the first gun to be 3D printed. The hype was largely due to the fact that most people don’t understand how easy it is to build a gun without a 3D printer. To that end, you don’t even need access to metal stock, as [FarmCraft101] shows us with this gun made out of melted aluminum cans.

The build starts off by melting over 200 cans down into metal ingots, and then constructing a mold for the gun’s lower. This is the part that is legally regulated (at least in the US), and all other parts of a gun can be purchased without any special considerations. Once the aluminum is poured into the mold, the rough receiver heads over to the machine shop for finishing.

This build is fascinating, both from a machinist’s and blacksmith’s point-of-view and also as a reality check for how easy it is to build a firearm from scratch provided the correct tools are available. Of course, we don’t need to worry about the world being taken over by hoards of angry machinists wielding unlicensed firearms. There’s a lot of time and effort that goes into these builds and even then they won’t all be of the highest quality. Even the first 3D printed guns only fired a handful of times before becoming unusable, so it seems like any homemade firearm, regardless of manufacturing method, has substantial drawbacks.

Thanks to [Rey] for the tip!

Make A PVC Drill Press

March 31, 2017 by Elliot Williams 32 Comments

There are two types of people in this world: people who think that PVC is only suitable for plumbing, and people who don’t even know that you can use PVC to carry water. Instructables user [amjohnny] is clearly of the latter school. His PVC Dremel drill press is a bit of an oldie, but it’s still a testament to the pipefitter’s art. And you can watch it in action in the video embedded below.

Things we particularly like about this build include the PVC parallelogram movement, springs around tubes to push the Dremel head back up, and the clever use of a T-fitting and screw plug to hold the press in its lowest position. We wonder how one could add a depth stop to this thing. No matter, we love watching it work.

Anyway, this is just one hack of many that emphasizes the importance of a drill press in basically anyone’s life, as well as the ease of DIY’ing into one. If you’re in the PVC-haters camp, but have some scrap wood and drawer slides or plastic offcuts lying around, you have the makings of a rudimentary press — a welcome tool in the shop.

Mechanized One-Man Sawmill

July 16, 2016 by James Hobson 53 Comments

The title of ‘maker’ is conventionally applied to the young-adult age group. In the case of 84 year-old Ralph Affleck, a lifelong sawmiller, ‘maker’ perhaps undersells the accomplishment of building a fully functioning sawmill that can be operated by a single individual.

Starting in the trade at the age of 16 under his father’s tutelage, fifty years of working in sawmills saw him still loving what he did as retirement loomed. So, with pen, paper, and a simple school ruler he designed the entire shop from scratch. Decades of expertise working with wood allowed him to design the machines to account for warping and abnormalities in the timber resulting in incredibly accurate cuts.

With no other examples to guide his design — aside from perhaps old style steam-powered sawmills, and newer portable ones that he feels are inadequate for the job — much of the shop is built from scratch with scavenged parts. And, that list is impressive: four hydraulic cylinders from a Canberra bomber, levers from an old locomotive, differentials and gearboxes from a MAC and 1912 Republic trucks, a Leyland engine that operated for 13 years without the need for maintenance, and an assortment of old military and air force vehicle parts. This is complimented by his log skidder — also custom — that would look at home in a post-apocalyptic wasteland. Built from two tractors, it combines three gearboxes for 12 forward and 8 reverse gears(what!?), and can hit 42mph in reverse!

Path To Craftsmanship: The Art Of Throwing It Away

May 31, 2016 by Gerrit Coetzee 153 Comments

Some hackers build sharp, mildly toxic nests of parts, components, and thrifty finds around themselves. These nests, while not comfortable, are certainly comforting. They allow the hacker’s psyche to inhabit a locale as chaotic as their minds. Within these walls of stuff and clutter, stunning hacks pour out amid a small cloud of cursing. This article is not for them.

http://www.computerhistory.org/atchm/an-analog-life-remembering-jim-williams/ — Very few of us can actually function in a workplace such like that of the venerable Jim Williams (photo from linked article). Thanks to the commenters for mentioning him in the previous article.

For the rest of us, clutter is a Zen destroying, seemingly unconquerable, monster that taunts our poor discipline and organizational skill from the dark corner of our minds. However, there is an easy solution that is oft overlooked. Somewhat obviously, most organization problems can be solved by simply not having things to organize.

It’s taken me a very long time to realize the source of my clutter woes. My first tactic was to blame myself for my inability to keep up with the mess. A more superior human would certainly be able to use their effortless discipline to keep a space organized. However, the clutter was a symptom of a problem completely separate from my actual ability to keep a space clean.

Wooden Escalator Fit For A Slinky

August 9, 2015 by Kevin Dady 24 Comments

Our favorite mechanical master of woodworking, [Matthias Wandel], is at it again, this time making an endless staircase for a Slinky. Making an escalator out of 2×4’s and other lumber bits looks fairly easy when condensed down to a two and a half minute video. In reality a job like this requires lots of cuts, holes, and a ton of planning.

The hard part of this build seemed to be the motor arrangement. There is a sweet spot when it comes to Slinky escalator speeds. Too fast, and you’ll outpace the Slinky. Too slow, and the Slinky flies off the end of the escalator. Keeping the speed in check turned out to be a difficult task with the coarse speed control of a drill trigger. The solution was to ditch the drill and build a simple hand crank mechanism. The Slinky now can cascade down stairs as long as your arm holds out.

Join us after the break for 3 videos, the making of the escalator, a 140 step demonstration video, and a followup video (for geeks like us) explaining where the idea came from, whats wrong with the machine and possible improvements.

Thanks to [Jim Lynch] for the tip
