    That's not practical at all! How many time did you loosen the three screws to advance the cutter to work piece? 100 times maybe!! Because the center of rotation has to be fixed right under the work piece all the time.

      LOL! He didn't have to adjust them at all. The base plate is bolted to the cross slide.

      Looks like I'm the only who seeing the sense of your argument.f u feed using the crosslide then you lose your centre.u must advance the tool only

    • @intjonmiller
      @intjonmiller 6 років тому +21

      @@thewarlordscalling6537 You are correct that the center of rotation moves when you advance the cross slide, but you are not correct that it matters. The swing of the tool covers 180 degrees of the ball's circumference, and you advance the tool (and its center point) until it is directly plumb with the rotational axis of the part. Other ball turner designs require that you start on center in both directions and advance just the cutting bit. This one operates more like a hand graver that is constrained in its movement. David didn't invent this, as he mentions, and he's only one of countless thousands of home shop machinists who have made one over the years. I assure you we aren't all so foolish as you believe. You simply didn't understand the way this is used differently from other designs (especially the variety which is based on a boring head mounted on the tool post).

    It's almost painful to watch such a small lathe and machinery, but when aligning that rectangular stock... fuck me, that is one master trick. Perhaps the finished product is a masterpiece. I'll be machining a super huge one for my lathe. Thanks for sharing!!! You've earned my humble subscribe

    • @DavidCambridge
      @DavidCambridge  7 років тому +2

      Thanks Virginia. The radius is limited by the distance between the bar stock and the bottom of the tool holder, which in turn is governed by the size of the lathe you make the tool for.

  • @427med

  • @jimturner9697
    @jimturner9697 4 роки тому

    How is this held in the cross slide. Could I add a part that would fit to a t-block. That way you could just advance the tool into the work and this would be faster, or is my thinking cloudy on this.

  • @SharkyMoto
    @SharkyMoto 7 років тому +2

    hey david, nice work, i really like it! theres one thing that might be unclear: when you make the tool holder, you take the height of the lathe center and mill it to that exact height... but, if you place your insert on top, it will be above the center? a solution would be to take 2 of the inserts you want to use and shim the tool holder in the toolpost up for marking the thing, that would give a dead on result when the insert is mounted?

    • @DavidCambridge

  • @joedell71
    @joedell71 7 років тому

    Awesome video. I have been wanting to make one of these for my small lathe for quite some time. Yours is the most straightforward design that Ive seen. One question though. How did you affix it to the lathe carriage? I saw the four bolt holes. Do those line up with holes on your carriage?

    • @DavidCambridge
      @DavidCambridge  7 років тому +1

      Thanks joedell71 - that is correct. There are 'T' slots in the carriage that line up with the four bolt holes.

    • @joedell71
      @joedell71 7 років тому

      Ahhh Ok then your carriage has T slots in it. Mine doesn't. It's ok though. I can use what you've done and just modify it. I won't need a base plate like yours. My carriage has a round boss on it already that sticks up like the one you machined into your round part I'll just mount right to that with a thrust bearing underneath or something along those lines. Thanks for the reply.

      @jimjakosh2506 5 років тому

      @@DavidCambridge Thanks, that good to know. I made a copy of the Perfect Sphere jig from Carter products and had to use 2 bearings in the bottom so it was solid enough to do concave turning/ with just the one 1/2" thick bearing, it w was fine on convex ( ball) turning, but chattered like crazy on the concave cutting. I think I make one of these for my 9" metal lath - for jut convex turning.................cheers, Jim
