Soprano Ukulele (From a Log!)

Rob Salmon

There was a glorious old apple tree in my garden. It was right in front of my kitchen window, blocking all of our light... but it would be sinful to cut down.

October 2014 - The tree was laden by a burdensome overload of apples. It was a barely noticeable, mildly windy day, and down came the tree! As, the clean up began, I cut the tree into manageable pieces. There was one piece, that for some reason I liked the look of, I kept it in my shed, and said, one day I will make something out of that.

Fast-forward to 2018. I had bought a cheap set of carving chisels, and started to look at this log, and imagine what fantastical shapes I could reveal, when I started to carve.

I had never made a musical instrument, at this point, though I have since had a number of adventures. As I threw my tape across the log, my mind began to wander. My daughters 4th Birthday was impending, and I had been considering getting her a Ukulele. A quick google to check the size of a soprano ukulele...it looked like there may be a ukulele hiding in the log.

It is almost impossible to write a "step by step" for this project, without volumes of text, as such the photos on each step do a lot of talking. Furthermore, this instructable is really about providing inspiration for others for future projects. The instructable is generally written in the first person, I have no doubt that there are better ways to do some of the steps. There may even be steps or advice that is just plain wrong! - Its really about inspiration ...and fun. For the most part (except for fretting!) this is simply good fun, with a happy biproduct of a working musical instrument!

120v Metal Foundry With Lid Switch

IJustLikeMakingThings 

I have been wanting to build a metal foundry for some time but was torn between going electric or propane until I came across This Instructable that was electric but was only 120 volts. All the other builds I had seen had been 220 volt builds or used electric elements from stoves but I wanted to use120v and a heating coil. I also liked the ability to precisely control the temp because then I could also use it as a heat treater. I came across This Build which had a nice design and some great tips that I utilized in my design. I was able to use aspects of both of these designs to create my foundry.

I tried to design this to use tools that most makers should have or give you options for those with limited tools. At most, this can be made with a hacksaw, file, snips, and drill.

I wanted to include some safety measures to protect myself. I added a switch to cut the power if I lift the lid to prevent any chance of contacting the live heating coil wires. I also added a cover over the electronics, including the heating element wires. All other designs I saw had exposed wires and nothing preventing contact with the live heating coils.

Home Built 4x8ft CNC Plasma Metal Cutting System

Customfabricated

What is a CNC Plasma Cutting System? These are computer controlled machines that can cut through any electrically conductive material (steel / stainless / aluminum / copper). The machine takes a 2D computer generated sketch and translates it to a computer numerical control (CNC) system that is coupled with a Plasma Cutter. The Plasma Cutter uses an electrical arc and compressed air to cut through the conductive material.

I designed and built this system in my personal shop utilizing several off-the-shelf components along with some custom fabricated assemblies.

Check out the following steps for a detailed overview of my custom CNC Plasma build!

Plastic Brick Compressor

Rehaan33

Background

This is my IB HL Design Technology major project. It is a product that takes plastic waste and transforms it into bricks. This product was specifically designed for rural (developing areas) environments and as such, requires no electricity to operate. The production of plastic bricks in these communities can help to not only clean up their environment but also educate them on the plastic issue, provide sustainablebuildingmaterials as well as promote social entrepreneurship in these areas.

This is, unfortunately, a very specialized project as requires access to quite a few resources as you might notice when you read through this Instructable. If you have any questions, please do not hesitate to ask them in the comments, and lastly, please vote for this instructable in the Plastics Contest if you enjoyed it!

The Lucien Yeomans “secret” that was almost lost.
Your developing world school needs almost-free machine tools?
Your developing world factory needs unavailable spare parts?
You need a complex part that is too expensive to have made?
Need to bootstrap a factory but only have a few bucks?
No problem!
You just need a metal lathe. Metalworking lathes are necessary to the production of almost everything but are very expensive. In 1915, special lathes made from concrete were developed to quickly and cheaply produce millions of cannon shells needed for World War I. Lucien Yeomans, the inventor, won the nation’s highest engineering award for it but sadly the technique was almost forgotten after the war. We re-discovered it as a way to quickly make inexpensive but accurate machine tools for use in developing countries and in trade schools and shops everywhere. We made modern construction practical by replacing the original poured, non shrinking metal with cement grout.

DIY Microwave Kiln | Fuse Glass in Your MicrowaveShakeTheFuture 

In this Instructable, we'll look into way to make a microwave kiln.
For those who don't know what is a microwave kiln, here is a quick introduction.
Microwave kiln is a kiln that you can put in your regular microwave oven.
It does not use a wire heating element or gas to heat up. Microwave kiln is covered with silicon carbide.
Silicon carbide absorbs microwaves and turns them into heat.
Microwave kilns are usually used to fuse glass.
You can turn broken glass into amazing jewelry.

DIY 3D Printed Dremel CNCNikus
When I got my first 3D printer I was extremely happy with all the new possibilities to create things but after some time I noticed the limitations of 3D printing. Plastic is easy to melt, sometimes it's not mechanically resistant enough and most importantly sometimes doesn't look good. Don't take me wrong here, I love 3D printing and I like plastic (except plastic waste) but there are things that look, work or feel way better when made out of nonplastic material. Imagine all your furniture made out of plastic. Sometimes I prefer wood, when I need strength, metal (mostly aluminum) is a way to go. That's where CNC milling machines are used. Usually, the cost of such machine is really high, most of the hobbyist, small makers can't afford such expensive equipment. That's why the idea of building my own CNC machine sparked in my head

Velleman Vertex, Imprimam a Lua(!), como vender na Etsy, uma Forja de Propano, e quanto cobrar por uma Impressão 3D!

Como me farto de gabar esta minha Velleman Vertex, cá vai o porquê, e como podem verificar no Vídeo, também lá tem umas obas de críticas, não porque me estou a evidenciar, mas porque eles bem que podiam afinar melhor a coisa...

Querem uma Impressora sem Stress, todos os dias?

Tentem esta:

Maybe I'll translate this, one day, but for now, you can try and have it auto-translated, or something;

In a nutshell, it points out the good and the bad, of the Velleman Vertex, why it's ideal for non-geeks, and also shows you how improve it:

It has a slot inside for an USB -Printer Cable, so you can connect it to your PC, beware, room only for the 90 degree jack variety, uses a BuildTak magnetically fixing plate, and I love the thing, faults and all, 'cos it works without dramas and constant re-calibration.

If you connect it to your 'puter, when you cancel a print, be sure to switch the thing off, and remove the USB from the PC, to  avoid problems.

How to Make a Propane Forge

MaxPower1977

In this Instructable I show you how to make a high efficiency propane forge. I have made a few forges so I have a good idea how they go together but I will give reference and credit to Ron Reil and his designs, that is where I learned how to build them over 12 years ago.
This forge can be used for knife making, blacksmithing, glass making or anything else you can think of that requires heating up stuff to a really hot temperature.
I have access to a welder so I was able to weld some parts together for this forge but if you don't have access or know how to weld, an option is you can braze the parts together or be creative and bolt things together.

Now you will know HOW MUCH to ask for, not losinge either Money, nor Clients:

The True Cost of Running a Desktop 3D Printer

Jason King

 Whenever I show my latest 3D prints to people, the one question they always ask me is “How much did this cost to make?”
My answer is usually along the lines of “I’m not sure and I’m not worried because I’m going to make it anyway”.
This is a good question and my answer is honest and true, but I realised recently that my answer simply isn’t good enough. It’s at around this time that I received a comment on my Beginners Series Page relating to 3D printer running costs. If I may quote part of the comment:
 “I am researching printers and their various features and functions and have found plenty of suppliers who don’t seem to have a clue about printing supply costs relating to quantity on a reel or weight or either and offer little assistance. The one thing you don’t mention is how much does it cost you to run your printer and by this I mean electricity used per hour. It is impossible for me as a budding business owner to put a cost on my item if the makers can’t tell me how much power it uses. I have a kilowatt hour meter to test it but don’t have anything to test it on and I refuse to take anything on faith from these folks since they’ve not been overly helpful on all other questions I’ve asked to date.”
To quote part of my reply:
 “I’ve never worked out or tried to find out how much the electricity costs are, because I’ve figure that it’s negligible compared the other resources required, time currently being the biggest resource used in 3D printing. But I should, so maybe I’ll write a blog post soon about the true running costs of a 3D printer. I’ve not yet seen such information published and I think people will certainly find it interesting.”
To address this question I started by purchasing some accurate kitchen scales. Based on the weight of an object and the cost of the filament (plastic) per kg it’s easy to work out the material costs.
This was a good start, but I then started to think about other costs like electricity, equipment depreciation, software, repairs, 3D Printer Upgrades, consumables and of course the cost of all those 3D printing failures.
As you can imagine, working out the true cost of running a desktop 3D printer at home could be tricky, but I like a challenge and as far as I know, this common question remains unanswered. Up until now that is.

Simple Sheet Metal Brake: No Welding

makjosher  

I love working with metal, but I've always struggled to get perfect 90° bends. Generally, I'll stick the piece to be bent in the vise and smack it around until it's bent. Since it almost always bends crooked, I end up rebending - and generally just making a mess of it.

For my next project I was going to need to bend some cardboard, which inspired me to first tackle a bending brake. Since I knew I would end up bending things much harder than cardboard in the future, I designed the brake to handle thin aluminum and steel.

Inspiration for the design came from several other DIY brakes, such as this one by Improbable Construct and one by the Youtuber JDCD Design. Since I don't have easy access to a welder (and also try to avoid welding as I'm not terribly great at it), I modified the design to make it weld-free.

Electronics Components Storage

Alex in NZ 

Electronics is great fun, but you do end up with lots of different types of components which need to be stored individually.

I kept mine in a series of small plastic divided cases (Tactix brand), but the cases themselves were getting a bit out of control.

I liked J-Po's cabinet design but my cases had slightly curved edges which meant that they would not be held securely by the method J-Po had used.

Jesper75 had built a cabinet for the same style of cases, but I didn't want to have to cut, paint and fit the number of shelves which I would have required.

The requirements for my solution were to have as little space between the cases as possible and to use timber which I already had.

I decided to use aluminium extrusion to make holders for the cases, and since it would have been annoying to fit these once the carcass was assembled, I also decided to finish the surface before assembly. Unusual, and probably not an experiment which I will repeat, but a method which worked "well enough."

Cortesia da Sculpteo, há 4 números que devem sempre ter em conta, para produzirem uma boa Impressão 3D, e aqui seguem, para terem sempre um bom resultado final, sem desilusões nem desperdícios:

Never fail a 3D Print again: the 4 key numbers of 3D printing 

Missing faces, bad quality, printing rejection and production delay? When you design and send your 3D file for 3D printing, some issues can happen frequently. But don’t worry! If you keep the following 4 numbers in mind while designing, these issues can be easily corrected before you 3D print or order on a 3D printing service.

Which are those key numbers for 3D printing?

1-   The number of polygons

2-   The size of your 3D file

3-   The dimensions of your product

4-   The number of volumes and parts in your file

Charcoal Grill Forge: Become a blacksmith on the cheap

Mtownzach  

To me, backsmiths are freakin' badasses. The roar of the fire, and the ping on the hammer striking glowing metal; it's almost mystical. They are legendary figures that have been around since the Romans, manipulating the elements to create long-lasting, useful and desirable stuff. Since the industrial revolution and modern technology, this has become a lost art.

However, this is one hell of a survival skill. I'll show you how to make a forge on the cheap to get started. I encourage you to try it out.

Brass Casting - Got Nice Ingot

DuralM  

In this short article, if I can call notes about my humble experience an article :) I'd like to show how I casted 614 gram (1 lb. 5 oz.) round brass ingot. For many people who start melting and casting metals, it can be hard to melt brass, bronze, copper after for example, lead and aluminum. The main problem is high brass melting point.

That’s why I had to upgrade my blowpipe before melting and casting brass. It was a real challenge to exceed 900 °С (1652 °F).
