Part 3 — Homemade Screen-Door Spring

A screen or storm-door spring can be easily made of spring-steel wire. The wire is bent to the shape shown in the sketch and two turns given to the coil as shown at A. The ends of the wire are fastened to the casing and door with staples. Two or three of these springs can be attached to one door where it is necessary to have more strength.—Contributed by Wm.
