Abstract
A variable depth router and base assembly can include a ring-type, depth-adjustment mechanism. The base assembly can be a two-piece base wherein one piece is disposed inside the other. One of the pieces can include an annular lip or recess that can cooperate with levers on the adjustment ring to secure the router to the base assembly. The two-piece base assembly can facilitate the manufacture of the base assembly, can allow the use of different materials for different portions of the base assembly, and can provide a more economical base assembly. The use of differing materials can facilitate the using of more wear-resistant materials where needed while avoiding the costs of such materials in locations where it is not needed. The two-piece base assembly may allow various features to be economically incorporated into one of the pieces, thereby facilitating the manufacturing and assembly of the base assembly.
