Yes...the self-feeding arrangements on post drills and their little brothers, the bench drills, are truly neat.
North Brothers (the original Yankee tools, before Stanley bought them in 1946) came up with some really gizmotic tools. Their little eggbeaters, with three ratcheting settings (left, right, and double right, in which the chuck turns "forward" no matter which way you move the crank handle), are wondrous. The double right setting seemed like an unnecessary novelty setting to me until I realized that it allows quick drilling in tight spots and serves also as a kind of torque multiplier; you can crank rapidly back and forth at your body's optimal mechanical spot, and drill with noticeably larger bits than in any other setting.
