Hi! The wire is "Nicrothal 80", 0.3 mm thick. The foam is bluecore/fanfold. For this type of foam 2.5A though the wire gives a good cutting speed. The voltage will vary depending on the wire length. Good luck!

you can do it with a PC power source.. Since you can use 5 or 12v and also supports the current easily as long as the wire has over 10 ohms. Actually i tested it with 12v, and a guitar string (the thinnest) wich had about 20 ohms, and current for that resistance at 12v is about: I=V/r=12v/20ohms=0.6 amps. In 12v the source can handle in my case up to 9 amps. Overall the power used is 0.6A*12v=7.2 Watts.

I've been using this since 1980 but in a well balanced, wire supported frame (exactly the same pivot point technique but less wire sag). Using the positive template makes the work (dragging through the template) more difficult, especially around the leading edge. The final results are poor to say the least. A negative template is the only way with this method. You should make sure you use hard wood ply with well sanded and soaped edges. Fiberglass sheet is great but more expensive. By the way, he went too hot here. His wire cuts too fast and melts too much of the airfoil at the tip.

@hornos27hotmailcom
6 жыл бұрын
hola, las medidas son de acuerdo a las necesidades de cada persona en el corte a realizar, lo basico es el alambre de corte que es de un material llamado ferronikel, asi se conoce en mi pais, es un metal que tiene las caracteristicas de calentarse electricamente sin romperse ( es con lo que fabrican las resistencias calefactoras de ambiente ) y lo otro es una fuente de poder o de energia con la cual se regula le intensidad de calor que se nesesita para hacer en corte dependiendo del material que se va a trabajar, unos con mas otros con menos calor, estos aparatos regualdores controlan tanto el voltaje como el amperaje que circulara por el alambre de ferronikel y asi hacer un corte perfecto. las fuentes de poder los consigues en tiendas de electronica especializadas que pueden ir desde 0.5 volts a 35 volts, y de .100 mA a 15 Amp, es solo de buscar la mas economica ya que no se necesita precision de laboratorio.
