Mirad cómo hago un TORNILLO SIN FIN de rosca trapezoidal en mi torno #torno #tornillo #mecanica

I'm here again with a video in which I make a trapezoidal thread WORM SCREW. I do it on my little DIY HBM lathe. A big lathe job! So you can see everything that can be done in these small machines. I am sure that if you have a professional manual lathe, you will do these jobs faster than me.
Take a look and see what you think!
