This article shows a tool for holding the cutter on a common engine lathe whereby large radius spherical concave or convex patterns can be cut. Fig. 1 shows the tool in position for cutting a concave radius. The radius is controlled by bar 11 which is mounted between pins 12 and 13. The holes for pins 12 and 13 are drilled and reamed in the bar 11 to the length of the desired radius. Block 14 is clamped to the ways 15 and 16 of lathe 10. Block 17 is clamped to the cross slide 18. Lathe tool 19 is set to the work piece 20. When cross slide power feed is engaged, the tool is moved in the desired radius. Fig. 2 shows the tool in position for cutting a convex radius. In this case, block 14 is brought to the opposite side of the cross slide carriage 18 and block 17 is rotated by 180 degrees.
