Façam uma mesa de Plasma CNC! E/ou uma Impressora 3D por menos de 200 dólares, cortar madeira em espiral, uma cadeira de rodas para Cães(!), Joalharia, e um abre-garrafas com um Prego!

CNC Plasma, oh, Yeah!

Podem fazer esta Mesa de corte por Plasma CNC, que vos abrirá um sem-fim de possibilidades, corta chapa de Metal, faz tudo o que uma mera cortadora Laser CNC não faz...

CNC Plasma Table
So , you've bought a plasma cutter and you wish you could accurately cut your designs in metal. Tracing lines by hand gives disappointing results and CNC Plasma tables are way out of your budget. Sound familiar? Well, that's what I thought anyway!
If you have not bought your plasma cutter yet - there are a few things to bear in mind!
  1. The cutter must have 'HF Start' (Cheap cutters sometimes use 'scratch start' where you have to touch the torch on to the metal to strike the arc. Sadly, these will not work with CNC, least not this one!)
  2. If you have the option (can afford it) buy one with 'Pilot Arc'. If the torch moves over a poorly conducting area of metal such as rust, paint or a hole, the arc can go out and it will stop cutting. A Pilot Arc, like the pilot light in your boiler re-lights the arc if it extinguishes. It means you can cut pretty much anything no matter how grotty the surface looks.
  3. If you can, go for a branded cutter. Hypertherm are probably the best - or at least best known. They will give you the best cut quality and cut thickness for a given quoted power (some of the cheaper ones are a bit optimistic with the quoted power and cut thickness!). I started with a cheap cutter (which was actually pretty good) then upgraded to a used Hypertherm 40A machine which was cheaper than a new 'no-brand' machine.
  4. Go for the highest power you can afford. My original 30A cutter claimed to be able to cut 12mm thick - but the most it could realistically cut was 6mm. My new 40A Hypertherm claims 19mm cut thickness - and can indeed cut it (not very tidily though). It will cut nicely at 12mm thickness though.
This plasma table has been designed to work with whatever plasma torch
you have whether hand-held or a full blown CNC Torch. The mounting plate has been designed to be adaptable as possible. You can either attach the torch with zip-ties or U Bolts depending on how often you need to take it off.

E, ou, podem também construír esta Impressora 3D por menos de 200 Dólares, o que é muito bom para as Finanças domésticas!

Building a 3D Printer Under 200$

Hello everyone
In this instructable I will show you how to make a 3d printer under 200$.
This 3D printer -Tower Simple XL, Maybe I should call it 3D printer of Sauron, lol.
This 3D printer have 6* 6* 6 Inches build volum and you can build it without any 3Dprint part.(*Laser cutting needed*)
You can follow my Twitter to get the latest information @AlmusYang.

#10k views a day,it's awesome! "Place for filament roll" added on step 22 and step 23.

Eis uma habilidade bacana de Carpintaria, que bem pode ser convertida para o Plástico, cortem as vossas varetas em Espiral:

Spiral Cut a Wooden Dowel Using a Table Saw

My imagination was recently captured by an Instructable by a user named Seamster on how to build a wooden marble coaster. Since it looked like it was within range of my very limited woodworking abilities, I decided to attempt building one of my own. The only real sticking point was the spiral screw used to bring marbles to the top of the coaster.

Seamster used a Dremel to hand-carve the screw from a rounded piece of 2x4. I initially tried this with a store-bought wooden dowel, but quickly lost patience with the process (it turns out that I'm far lazier than I thought). I decided to see if I could figure out a faster way to carve out a wooden screw. I quickly hit upon a very simple method. This has probably been done before, but I'll document it here, just in case.
Step 1: Equipment and material
Picture of Equipment and material
The only woodworking equipment you will need to do this is:
- a table saw with a decent blade
- a miter gauge (pictured)
- a drill
- a suitable drill bit for your screws
- a clamp
- a screwdriver
- a pencil
...and that's it!

E para os nossos amigos de 4 patas, que podem ter perdido o uso dalguma delas, eis esta ideia meritória, uma Cadeira de Rodas para Animais!

Adaptable Wheelchair for handicapped Dogs
A few months ago we discovered Luisa, a handicapped puppy who was born without forelegs on the website of an animal protection organisation ( and decided to build a 3D-printed wheelchair for her. In the meantime we finished the wheelchair and have adopted Luisa. This project is open-source and we want to give everybody the opportunity to help a handicapped animal with this instructable and the 3D-Files we uploaded with it.
The Wheelchair comes in two sizes (The bigger size consists of several parts, so that it can be printed on smaller printers as well) and is adjustable in every possible aspect (width, height,camber,...).
All printed parts were printed by my company ( on our biggest 3d printer (Multirap M420). Of course the files can be printed on any printer, as long as the print area is big enough.

Eis uma ideia que pode ser uma maneira impecável de arranjar Fundos para as vossas Engenhocas e Projectos, como fazerem cráchas, medalhões e o que quizerem, com este aspecto:

How To Make Pierce Work Jewelry

This is how to make jewelry items out of sheet metal with decorative holes. I will show you how to make a pin with the piece I cut out. There is almost no limit to what you can make with enough thought behind this process.
I am using a .80mm thick plate of sterling silver to demonstrate. I will be cutting out a rose design. I will be making this into a pin so I will need the clasp, hinge, & pin parts as well. I am also going to add color epoxy to this later on, you don’t need to do that. I will talk about finishes & other options later. Last but in no way least you need a design to cut out. I went to Google & looked for line art flowers to get my design.

E isto cai na Categoria da Magia de Cabeça e Mãos, como se faz um Abre-Garrafas só com um Prego, uma tábua, e um ímane de Neodímio:

Nail Bottle Opener

I've seen these nail bottle openers online, and thought I would make one. They are super simple, but still very interesting, it can basically be a block of wood and a nail. I also wanted mine to be a little bit smaller and look better.

For this project all I used was:

- Scrap 1x4
- Scrap Nail, I used the biggest one I could find laying around
- Neodymium Magnet
- Special Walnut Colored Stain
- Epoxy
- Shellac Finish
- Template
- Black Spray Paint
