The second pocket 151 is formed within the second panel 116 that terminates at the end face 176 of the second panel 116 (block 906). The pair of dowel bores 194 are formed at the end face 176 of the second panel 116 (block 908), though in some implementations, the dowel bores 194 may be omitted. One of the alignment dowels 171 is coupled within each of the dowel bores 194 (block 910). The alignment dowels 171 may be coupled within the dowel bores 194 via an interference fit or adhesive, for example. The master dowel bore 168 and the slave dowel bore 170 are formed in the end face 157 of the first panel 114 (block 912), though in some implementations, the master dowel bore 168, slave dowel bore 170, and/or both may be omitted. The master dowel bore 168 and the slave dowel bore 170 are adapted to receive one of the alignment dowels 171.

The first shield portion 182 of the shield 153 is coupled within the second pocket 151 via the adhesive 152 in a manner that allows the second shield portion 184 to extend from the end face 176 of the second panel 116 (block 914). When the first shield portion 182 is coupled within the second pocket 151, the inward facing shield surface 154 can be substantially flush with the inward facing second panel surface 120.
