That's the only reason I follow this group. I own no machine tools more complex than a drill, but I'm interested in inexpensive ways of doing relatively precise machining. The most complex job I've done with my drill is to use it to drill a 1/8 inch hole the length of a 6 inch rod. The fairly well-known trick is to clamp the drill in a vise and chuck the rod in the drill. I had to drill from both ends of the rod, and the two holes met quite nicely at the midpoint. Keeping the tool fixed and rotating the workpiece serves to keep the borehole centered on the axis of rotation. Doug Jones jones@herky.cs.uiowa.edu
