Homemade Metal Lathe DIY Spindle Headstock by Drill Chucks

joulethief669 

A lathe is a piece of equipment used for shaping wood or other material. It consists of a base, which can be mounted on a bench or work table, and then, on either side, the headstock and the tailstock. The headstock has the spindle bearing which control the spindle, the part of the lathe which turns. The tailstock helps balance the spinning headstock, and features a stationary hollow horizontal access for a steel cylinder, which can be adjusted for accepting or stabilizing different sized tools and drill bits to cut the spinning material.

Propane Tank Aluminium Smelter (No Weld).

NphRandom 

For a long time I had been watching YouTube clips and reading about people making their own aluminum smelters and figured one day I would go ahead and make my own. Time passed and there was always another project or reason why I never got around to making one.

Then I decided one cold winter’s day to go ahead and make one so that it would be ready for spring when the weather turned better and I could go ahead and start melting the aluminum I had been collecting.

This is a link to NphRandom Blog.

PaperQuad DIY Quadcopter

YoseiI 

A few months back, my friend, Kevin, came up with the brilliant idea of melding the art of papercraft with his newfound interest in quadcopters. Naturally, being an engineer myself, I quickly fell into the rabbit-hole that is the multirotor hobby and together we began developing paper frames for our small micro-scale quads.

The basic idea went something like this: After flying the factory-built quads for a while, we began to get curious about altering the configuration -- what would longer arms do? What if we flipped some motors upside down and ran them backwards? What if we made a long and narrow quad? Short and wide? We figured that folding up some paper and gluing it together would be a great way to test these different configurations quickly and cheaply.

After some tinkering, we thought that this could actually become a great activity for kids of all ages (including distinctly adult-looking ones) -- it's inexpensive, offers endless possibilities for customization, and is incredibly fun! What's more, if the quadcopter crashes and breaks, you aren't dead in the water -- just recycle the old frame, print out a new one and you're off to the races again.

This Instructable is meant to be a getting-started guide to making paper quads. Feel free to share designs, knowhow, and let's see what comes out of it! Kevin and I have started a website dedicated to this project where we will post more PaperQuad-related content: PaperQuad.com

Make a Custom Bic Brander

JamesH76

In this Instructable I will show you how to 3D print your very own custom Branding Iron that snaps onto a Bic lighter!

You don't need a 3D printer, just an image, an image editing program like Pixlr and Shapeways.com to print your brand in real steel.

Disclaimer:

Yes, this is a branding iron, they get hot! Don't do anything stupid with one of these, like burn yourself or an animal! If you do, please don't blame me! :)

Second Disclaimer:

I am the designer of the branding iron, I 3D modeled the base file that your custom image gets extruded from on Shapeways, as the designer of the brand I get a bit of the profit for the sales on Shapeways ;) Don't hate me, your dollar is like a high five and makes my day more awesome :)

Cheap flying Lego quadcopter
Weseley

Ever needed an excuse to start building Lego again? Now is the time! Turns out Lego bricks can be used to build a perfect symmetrical frame for your quadcopter! And... it's super cheap.
I used Lego Technic because it has holes in the bricks. You can mount the motor's with tie wraps through the holes and it's an ideal weight reduction. For the motor's and flight controller I used parts from the famous Hubsan X4.

Microwaves enable economical recycling of plastic-aluminum laminates
Darren Quick

You may not know what they're called, but odds are you've eaten or drunk something from them. I'm referring to plastic-aluminum laminate (PAL) packaging, which has long been used for toothpaste tubes and in recent years has gained popularity as pouches for food, drink and pet food. Although it threatens to approach the ubiquity of the aluminum can or plastic bottle, PAL packaging lacks the familiar recyclable logo found on cans and bottles. But that could be set to change, with a process to recover the metals contained in PAL packaging, developed some 15 years ago by researchers at the University of Cambridge, now being demonstrated in a full commercial-scale plant.

An Open Source Plastic-Recycling Machine, From the Inventor of Phonebloks 

Margaret Rhodes

When a young Dutch designer named Dave Hakkens released Plonebloks, a concept for a modular phone, it set the internet on fire and helped Google along the same path. The explosion of attention was an accident. Hakkens, a recent graduate of The Design Academy in Eindhoven, actually had another thesis project in the works that he planned to pursue: Precious Plastics, a series of magpie-like machines that turn discarded plastic bottles and trash into new housewares. Like Phonebloks, it’s aimed at reducing waste, and creating a long lifecycle for the goods in our lives. He’s just recently open-sourced the designs, for anyone to download.

7075 aluminium alloy

From Wikipedia, the free encyclopedia

Aluminium alloy 7075 is an aluminium alloy, with zinc as the primary alloying element. It is strong, with a strength comparable to many steels, and has good fatigue strength and average machinability, but has less resistance to corrosion than many other Al alloys. Its relatively high cost limits its use to applications where cheaper alloys are not suitable.

7075 aluminum alloy's composition roughly includes 5.6–6.1% zinc, 2.1–2.5% magnesium, 1.2–1.6% copper, and less than half a percent of silicon, iron, manganese, titanium, chromium, and other metals. It is produced in many tempers, some of which are 7075-0, 7075-T6, 7075-T651.

Quick and cheap aluminum melting furnace setup

robbtoberfest

This Instructable shows a quick and cheap setup to melt a few batches of aluminum for casting before the thin metal equipment starts to break down. Actually the 5-gallon bucket furnace will last quite a long time, over a dozen uses easily. This uses BBQ charcoal as the fuel and a hair dryer as the blower, it'll melt a small batch of aluminum in about 10 minutes. Most of the materials to build this can be found in dumpsters; the only cost here is the charcoal fuel, duct tape, and the $1 yard sale hair dryer. Recycle old lawnmower parts, computer/stereo parts, and beer and soda cans to make awesome new things with them.

Honda develops new technology to weld steel and aluminum together

By Ben Coxworth

Although some engineers have had success in spot welding steel and aluminum together, it has largely been considered impossible to achieve reliable, continuous welds directly between the two dissimilar metals. That changed last Thursday, however, when Honda Motor Company announced that it has devised a technique for doing that very thing. The results, which include lower vehicle weight and better performance, can be seen in the 2013 Accord.
The Honda team developed a variation on Friction Stir Welding, in which metals are joined via mechanical pressure – it's the same technique that has been used for experimental steel/aluminum spot welds in the past. As Honda explains it, “This technology generates a new and stable metallic bonding between steel and aluminum by moving a rotating tool on the top of the aluminum which is lapped over the steel with high pressure.” The welds that result are reportedly as strong or stronger than those made using regular Metal Inert Gas welding.

Incredible 3D printed octopus submarine model 

Introducing the OPUS V.

Sean Charlesworth made the OPUS V: Octopod Underwater Salvage for his master’s thesis project. He graduated from the Digital Imaging and Design program at the New York University School of Continuing and Professional Studies.
This octopus-inspired fantasy submarine was made with 3D modeling and 3D printing, including the (working) mechanical parts. It’s rare to see a 3D model with such an extraordinary level of detail. Watch the video after the jump to truly appreciate this model. The outer hatches are removable, inner iris door rotates open, the the tentacles bend and flex.
