December 24, 20187 yr so ummm I got a bug up my tail I just had to have a gizmo to turn spheres. Got some 4" round stock and made the body that runs on a large diameter taper roller bearing ans some 1" steel flat stock and made the other parts. Some how I didn't think one inch was over kill. It was. So it's almost done. I gotta take it apart and install the groove for the large o-ring that will keep crud out of the bearing. B\ BUT I used it today to turn the large ball that I'll put on the end of the handle. Mind you I hadn't even a tiny clue how to use this thing. As it turns out it's gotta be centered under the centerline of the presumptive ball. OK that was easy. But because I hadn't mounted the handle - not yet decided on whether it needs a bend configuration to facilitate use - because of that I had to use other means to turn it. Crescent wrench to the rescue. I was appalled at how easy it was to cut steel even a good heavy pass. I ended up just grabbing the thing with my fingers and operated it that way. The forces on this giizmo are not heavy at all. Turns out one inch was definitely over kill. well it works no pics yet but here's a vid of me turning the component that the handle mounts to https://photos.smugmug.com/Tools-I-made-or-Purchased/i-qHdjzG7/0/9b990da6/1280/20181220_124847-1280.mp4 Edited December 24, 20187 yr by Cliff
December 25, 20187 yr Author here's a vid of the assembly. Of course I took it apart again to pack it with grease. But there it is. https://photos.smugmug.com/Tools-I-made-or-Purchased/i-Fqcv5K7/0/35c3e45e/1920/assembling the sphere turning tool-1920.mp4
