Precision Board Plus

High density urethane foam that is ideal for milling

Precision Board Plus High Density Urethane (also known as tooling board, a competitor to RenShape or Ren board) is a closed cell rigid urethane foam board that can withstand up to 200º F continuous exposure. It can be cut or bonded into a variety of shapes for final machining or shaping. Higher machine feed rates are easily achieved compared to wood, epoxy and alloy substrates. The material mills beautifully and is safe to laser cut/laser engrave. It has a density of 48 lbs per cubic foot. Buy everything you need to glue the material, repair nicks or holes, and prime for your final finish.

Se a vossa desculpa para não fundirem Alumínio era que "é muito complicado", mais fácil que isto, não há, com o que estiver mais à mão:

Recycling Aluminum (Aluminium) - Make your own Al foundry.  

gavargas

It has always been a very fascinating thing to see the things that we as humans have been able to accomplish through time. How we were able to build amazing things, utilizing only our imaginations and the resources around us.

This project is no stranger to these feelings I have and can teach a lot of things to anyone attempting it. We gave it a try at our hackerspace H3 Laboratories
There are various ways that you can do this project of course, so you can take ideas and go melt some aluminum at your house or hackerspace. Invite some people over and melt Aluminum together. It may look simple but it is very enjoyable and camaraderie forming.

Não há queenganar, este é um Isqueiro tipo Zippo, muito simplificado, e não custa nada incluír uma tampa para o Depósito, nem que seja um Parafuso com uma Anilha de Borracha, numa Porca soldada ao depósito:,

Storm lighter

Storm lighters are nice.
Storm lighters are useful.
But storm lighters are expensive. Too expensive for what it is: a sturdy fuel tank combined with a starter.

Here's a way to boost up an ordinay lighter into a cheap, water- & stormproof fuel torch.

Needs:
- some alu tubes in different sizes
- a few brass caps
- a lighter
- a few tampons

E eis a última novidade de David Landis, um Livro para Colorir...

3D! 

Alguém tinha de pensar nisto, colorem as Figuras, e depois, viram Papercraft.

Com tanto Criativo que anda por aí, sem meios para nada, e enfrentando uma cambada de bimbos que não arriscam em nada, mirem-se no exemplo deste empreendedor irrquieto, que vai alegremente lançando os seus fantásticos Livros, como este pelo Kickstarter...

FAÇAM OUTRO TANTO!!!
