 One of the basic needs of woodworking is to drill holes. So the next few shorts, I'm going to explore three historical hand tools that met this need and see how each compare. First up, the pump drill. Getting as early as a Roman era, the pump drill was an upgrade to the earlier bow drill by using a flywheel to increase the natural momentum and allow each drill bit to rewind itself so it can be quickly spun back and forth with each pump. Unlike later drills I'll be making, this one drills in a back and forth spin. So the bit needs to work both directions. So basically be a sharpened diamond. Then let's use this drill head to cut a hole on the board, add some leather straps and we have the completed drill. Next up we'll make the auger drill, which has the advantage of only spinning in a single direction.
