Sphere in a Cube Continued from PreviousPage.As shown in Figure 3 the items are: a woodencube of good dry hard wood, a center punch, a scribe, acenter marking device of some type (this is the Vicmarcunit), and an undercutting tool to cut the ball loose fromthe cube. The undercutting tool was made from a 1-1/2inch wide carpenter chisel that was ground to a shape tosupposedly cut the top of a 2-1/2 inch ball. The handleis one of the handles from a Crown Chinese Ball tool.Figure 6. I then drilled three of the sides of thecube, leaving the opposite side from each holeblank for drilling on the lathe.Figure 4. Here I am using the Vicmarc centermarker and the scribe to mark the center onall six sides of the cube. Once the centers weremarked, I used a spring loaded center punch tomark the point for the drill to center on.Figure 7. At this point, I moved to the VicmarcVL-100 lathe with my Vicmarc chuck with thesmall jaws. The jaws will open wide enough togrip the inside of a 2 inch diameter hole. The faceof the jaws were placed against the bottom of the2” diameter hole.Figure 5. I then went to the drill press and using a2- inch Colt Forstner Bit, I drilled a hole ½” deepand then marked the drill with a Sharpe Ink Penso that all holes could be drilled approximately thesame depth.Page 34 More Woodturning June 2010
