Glue up the box

Attach two cleats ( C) to the inside of each part to fasten the front and rear panels ( Photo 6). These are

glued 5/8 in. in from both the front and the back of the enclosure. Be sure the joints fit together correctly, then apply glue to all surfaces of the sockets and clamp them tight ( Photo 7). Check the diagonal measurements of the box from corner to corner to ensure that it’s square.
