The easiest of these to examine is the sliding of equipments and tailstocks over the ways of a lathe to maneuver gears and hold wood. If there is uncertainty in the movement of either it is generally because of rust on the finishes or ways that have toughened on the metal. Remove the tool rest banjo and tailstock from the lathe and look for either on the underneath of each. Clean finish and rust from the ways, tailstock and banjo with cleaner, steel wool or fine sandpaper and apply wax on the ways for rust prevention and easier movement prior replacing the banjo and tailstock.
