--- Quote from: raynerd on January 28, 2013, 04:24:38 PM --- I`d love to see a video of them actually using the thermite reaction practically. We have to teach that it is used to "repair railways lines" but have no video showing it and in all honesty, no proof that this actually is done other than me being told to say so! Chris --- End quote --- Chris, Plenty of vids on YouTube e.g: Phil. (Have you had a go at cutting a pinion yet?) |

I've seen 'Cadweld' welding whuch is a similar type of process used for attaching large earth lugs to cables...Quite a sight to see but not with the naked eye... |

Andrew/ Phil, thanks for the links! Great stuff Phil, not had a shot at cutting the pinion yet. Borrowed mums deep fat fryer and it went only to 180! Father in law is going to put them in his temp controlled industrial oven tomorrow night! I'm all set up ready, just waiting to temper. I'm very excited ... By the way, did you cut from silver steel?
