I,m watching this post with great interest, and so far it is interesting. I,m building a machine, with guidance from a member on here (not sure if he wants naming). I,ve made a start to it, with a friend, but due to him being busy and me wanting a wee bit more in my machine, its down to guidance and myself. I now have the arc welder in place, (i,m not a welder), but cant wait to get going with it. I have an engineering background, so this doesnt phase me. I,ve went on the net for tutorials, but i,ve not learned anything new. My machine is being made out of 60x60x3mm steel, and i,ll put up a build, once my workshop is up and running.
