Isto fará de qualquer Engenhocas um Fabricante!
Podem juntar-se uns 3 ou 4 Engenhocas, e assim comprar um Kit de Mesa de Plasma destes, e montar, partilhando o tempo de uso, e com o dinheiro que fizerem, comprar depois cada um a sua máquina...

CNC Router Parts Unveils Their New Plasma TableMatt Stultz
When you think of a CNC (Computer Numerically Controlled) machine, you probably think of a machine with a router attached to it, capable of cutting its way through wood, metal, and a variety of other materials.Really, a CNC machine is a generic term for a family of fabrication devices. If you change the tool head, you can change the function and often the name. Add an extrusion head, and you have a 3D printer; a swiveling razor blade and you have a vinyl, paper, or cloth cutter; or add a plasma torch and you have a CNC plasma table capable of cutting through sheets of metal.While we have seen numerous CNC routers and 3D printers come to market, very few DIY or kit plasma tables have found their way into Makers’ hands.
E para os Aficionados do Aeromodelismo, podem agora fazer os vosso Modelos, com um Fio de Corte de Esferovite, ou Isopor, e pouco mais...
É bom!
Build Classic R/C Airplanes With New Method
whiteboardwarriors2
This Instructable will show how to build light-weight, electric versions of a couple of classic R/C airplanes quickly and cheaply using some simple methods. Other than a very simple hot wire foam cutter, which I will show, there are no special tools required. Using these techniques and materials, it should be cheap and quick enough that you can easily experiment with your own versions of your favorites and test many different designs with varying configurations of airfoils, wing dihedral, length, etc.The impetus for this project was Das Ugly Stik, designed and built by Phil Kraft in the 1960's as a quick to build, semi-aerobatic plane to test his radios in (Here). It turned out to be one of the best flying, most popular R/C planes ever. My goal was to be able to test various air plane designs quickly and cheaply. A good example is the photo above which shows two essentially identical airplanes except that one is shoulder-wing and one is low-wing which were built to settle the debate about which was better for dog-fighting - high wing or low wing.

É fácil "cozinhar" plástico em òleo ou àgua, a 200 e tal Graus, e fazer Placa de Plástico...
Mas eis um Engenhocas que viu um problema, a falta de reciclagem dos Plásticos, pois ele pôs Mãos à Obra, e tratou de fazer uma linha de máquinas para reciclar plástico, e está-se a dar bem com a Iniciativa!
Um exemplo a seguir, e sobretudo, um Site a visitar, pois ele explica como vós mesmos podem fazer exemplares estas máquinas todas! 
PRECIOUS PLASTICPlastic can easily be recycled. It needs relative low temperatures and pressures. Look around and you’ll notice plastic waste is everywhere around us. We just need to sort it and have tools to turn it into new things.
PRECIOUS PLASTIC – THE MACHINESThis project is a set of plastic machines, developed to set up a small scale plastic workshop. The machinery is based on general industrial techniques, but designed to build yourself. The machine is easy to use and made to work with recycled plastic. Whilst this entire project is still in development, the machines are shared open source online and improved by the community.
