ASSORTS Lathe Ball Turning Attachment – Round Base with Size Scale – Double Bit – Convex & Concave Metal Sphere Radius Turning Tool | Fits Myford & Similar Lathes | Precision Metalworking Accessory

Works great for aluminum! Haven't tried stainless yet? That will be the real test!

Takes a little modification for it to work flawlessly, but it’s worth it

Haven't used it yet as I need to make a raiser for it to fit my lathe ( Emco V10P) BUT initial impression is as expected, cheaply made, needs finishing ( deburring, loctiting screws etc) as another reviewer stated it should have a bearing on the pivot as I can see it will be a high wear point if used anything more than rarely but it should do the minimal work I'm planning on. Needs a scale on side for referencing radius it is cutting to at least get you in the ball park of what your trying for

5stars from a non machinist. I adapted this to use on a 9 in. South Bend lathe. Worked perfectly. Got an acceptable finish on my piece. No sanding or filing only wire wheel to shine it up.

This is a joke, there is no fine adjustment on the tool block and it rides in a square groove not a dovetail.

shipped without handle and there's a gap on the bearing assembly that will lock up the rotating mechanism if you try and tighten the screw all the way i had to make a bushing to keep the screw from locking it up and be able to be tight enough to not loosen on its own

Was not able to use it on my lathe,but it's a well designed tool,

Works ok,, but bearing could be improved to make it have less play... Still just a little loose, which doesn't give a great finish. A little tricky to set the diameter of the cut (manual measure).I had to make a custom fixture for my lathe, but it worked out ok..
