I think the boring head ball turning attachments are novel, but I worry that they are changing the direction of stress where the tools cut into the work in relation to the headstock. So, I started building my own ball turning attachment out of 5"x12"x5/8" plate steel. I marked it and drilled the corners, then cross drilled the pivot point, and drill-cut the inside edge.
Then I spend too much time at the bandsaw cutting it out :
I subsequently used a grinder to clean it up. I still have yet to open up the pivot holes, install bushings, and broach the swing arm to hold the small tool holder in place. I think it will do, though.
