Picker

There are various devices for picking out small patterns from the sand, including screws, spikes and spring-lifters, etc., all of which are designated by the general name of picker. The best picker for very small bench-work patterns that are made of wood and do not require duplicating is a fine-pointed steel wire. But if a large number require to be made from one pattern, have a small hole bored well in, or through if the pattern is thin, and use the spring-lifter. A metal plate inserted neatly at the orifice of the hole will prolong the usefulness of the pattern indefinitely. See SCREW; SPIKE; SPRING-LIFTER.
