  • it's all fun till it jumps out the chuck and knocks the planet off its axis

  • Rmember you can take metal off but ya cant put it back on, No preasure though. I think we had the same boss lol. Alot of people are intimidated by the big jobs, though to be honest its easier to go wrong on the small ones .001 to deep and start againbig jobs usually means big tolerance I love em

  • @Axbent Yes but its not quite the same, there are some applications where those methods arent an option. But I do understand what your saying Ive dealt with both methods before

  • @GeneralG1810 Sure u can put metal backon, there are metal sprayers and welders!

  • Ran a 110" swing at Newport News ship, she was old and big but could really move metal. Also a 72" that we made the shorter prop shafts on. Good work but it ran out and so did I. Dave.

  • i knock 2 or 3 of these out before smoko

  • That's a toy, and whoever is running it is an pussy, even my apprentice's take bigger cuts with more rpm.

  • @GeneralG1810

    They have to. Steel expands and contracts too much with temperature change. Not as much reason to worry about a thousandth.

  • Gotta love big old machines, note the coffee can to catch the oil leaking from the feed screw shaft seals at 0:22.

  • Is that Lathe from Harbor Freight??

  • dont go under tollerance!!!!!

  • You's and your lb's. Use kg's for fuck sake!!!
