Today we use some 4140 prehard to make a new leadscrew for the 2-speed gearbox and tailstock that you saw us build for our Lion lathe in the last few videos. Enjoy!

    I work in a Dubai industry of machine preter and was very impressed to see your work🎉

    It's amazing how the entire lathe machine moves as the tool post is still during cuts. Fancy smancy !

    The 4140 looked like it machined beautifully…LOVE that American lathe

    Really appreciate your videos. I have a great lathe and a great mill. I'm completely self-taught & greatly respect your knowledge. There are a few channels that I depend on for learning and you're one of them. I can't ever thank you enough for how much I've learned from you. Your impact on the world of machining will be permanent and good for all of us.

    Love watching single point threading! Follow rest was definitely the way to go, better safe than sorry! Nice looking work for sure
  • I love your content, and you exude confidence when explaining and performing your work. You have a new subscriber. I was surprised to hear uncertainty when you talked about your drawing. It looks very good, and I'm creating and using them all the time. Here's a hot tip for your next drawing; use ordinate dimensions. I started my career as a machinist, and I always had the absolute XY on the DRO set on the left front corner of the fixed jaw of the milling vise. I do my CAD drawings the same way, with each datum dimensioned like it will come up on the display.

    Great camera work on the threading. I liked the hanging rotary table. You do what you have to do to get the job done!
  • @mudnducs
    Xlnt! I like the follow rest…it looks like it burnished the tops of the threads. Really, very nice!

    @Vanover Customs Very smart presentation of the risk your work piece will move and how to mitigate. I've avoided turning per-hardened steel for this very reason several times, now I think I can tackle it. Thank you.
  • Very Nice Job. .looks great. . should last a life time..

    The company l served my apprenticeship at and retired from we had some LeBlond Regals with Two Speed Tailstocks. They also had worm gear driven Depth Dials. Much nicer than relying on the scale on the quill
