Nice plans, I'm still leaning towards the boring head type . Easier to use unless you have a dual compound set up like a turret lathe. Guess I'm to old an lazy.
I am guessing that this will replace the protractor for the compound on the cross slide. If so the dimensions for the holes for the "ball turning hold down base" will have to be adjusted for my lathe at least. I have a 8 X 16 Sieg SC4 and a quick measurement for those dimensions would be the width between the holes would be 2.95 (75mm) vice 2.96 and the length would be 3.38 (95mm) vice 4.00 inches. Also the depth of the slot on the "ball turning Rotating Body" was left blank since it will have to be set for each lathe.
