Here is a pic of my drill press, actually two of them, and they are identical. The bottom one retains some of its original red paint, the top one I picked up as a spare. I use these by clamping them in a vise, crank handle to the right. The feed wheel on the right, moves the bit in. The feed wheel on the left brings the work piece in closer. I built the box to transport one, for blacksmith events, old cast iron is fragile. These use the tapered square shank bits as used in a brace drill. Have a few sets of metal cutting bits, and they certainly do work. Anyone else have one?
