Quick Change Ball Turning Tool Kit
Material and drawing kit including drawing set, all stock, bearings, and fasteners required for completion of QCTP ball turning tool. Tool is dimensioned for AXA size toolposts but can also be machined for the larger BXA.
The quick change mounting and adjustment stops for height and centering means fast setup for turning spherical sections. This is a variation on the Radford tool in which the movement of the cutter is over the top and the cutting action is tangential. The cutter is a readily available 3/8" shank boring tool. While intended primarily for convex spherical contours such as the ball handles shown, I have also tested it cutting concave faces and shallow concave radii on shanks.
This kit requires extensive machining using both a lathe and mill and incorporates a dovetail slide for ball size setting.
