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.

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
@intjonmiller5 жыл бұрын
@@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).

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?

I really like it, but the center pin is hokey, with threads on a turning surface. Should have turned the center pin from scratch, so the nut would tighten at the proper time, I know the outside circumference is kept true, so probably doesn't matter really.
