Ball & Radius Turning Attachment
heavy duty radius attachment was designed for an Emco Maier "Maximat
Super 11" lathe but it can be resized and/or modified to fit most 9"and
It will turn convex radii up to 3" diameter and concave radii up to
4-1/2". There are fine feed screws on both X and Y axis movement for
accurate control of radii on the work piece, allowing for flanges on
hemispheres and other circumstances. The unit features dovetail slides
with integral adjustable gibs.
The tool holder is designed for maximum flexibility in positioning the
tool. All component parts are very heavily designed and the pivot
system has a very large bearing area. Sooner or later most machinists
will need this type of attachment for the lathe.
The plans set consists of 6 sheets of drawings.

checked over the very excellent drawings and am impressed. I'm an
ex-Boeing design engineer, and I've worked with a lot of drawings and
yours impress me." - Jack M. Nuckols (Hanson, Idaho)
