A cheap, effective turning tool.
Three-jaw lathe chucks are virtually indispensable for a turner, yet the cost of buying one can be prohibitive. Three-jaw chucks are useful when turning small pieces at low speed, and permit multi-axis turning. This shop-made chuck can be made from scraps of maple and a few machine screws. By changing the arrangement of the screw holes, this can also be made into a 4-jaw chuck.
