The Locks: Patterns & Instructions - This section provides the plans and detailed instructions for each of the 14 lock projects in this new edition. The clear assembly instructions describe when and how to use the technical information provided in section one. The authors have maintained their original trademark style that relies on well-illustrated step-by-step instructions that guide you through the whole lock-making process.

Bend the tail <strong>of</strong> the tumbler so that it sits just above the bot<strong>to</strong>m <strong>of</strong> the bolt.<br />
Hacksaw a 1/4” (6 mm) long notch at the intersection <strong>of</strong> the spring and the tail <strong>of</strong> the tumbler and bend that<br />
section <strong>of</strong> spring downward so that it will rest on the <strong>to</strong>p edge <strong>of</strong> the bolt.<br />
Bend the spring <strong>to</strong> shape and form a loop that will fit over a 16d common nail. Curve the remainder <strong>of</strong> the<br />
spring upwards until it crosses slightly past the <strong>to</strong>p <strong>of</strong> the side plate reference line on the backplate pattern.<br />
Trim the end so that it fits inside the lock.<br />
File a 1/8” (3 mm) round tenon on the end <strong>of</strong> the pin. Install the pin and slide the tumbler over the pin.<br />
Slide the bolt against the front bolt<br />
guide and scribe the location <strong>of</strong> the<br />
tumbler locking the pin on<strong>to</strong> the bolt.<br />
Slide the bolt against the rear bolt<br />
guide and scribe the location <strong>of</strong> the<br />
locking pin on<strong>to</strong> the bolt.<br />
Use a round file <strong>to</strong> cut detents at each<br />
scribe mark on the bolt. This will<br />
create a working lock that is simple<br />
<strong>to</strong> open where there would be no<br />
damage <strong>to</strong> the lock should the key be<br />
misplaced.<br />
