Step 6 Make Mounting Brackets

These brackets are designed to pull the speaker baffle tight against the doorway trim. The blue end of the bracket shown below slides in between the trim and the end of the door (on the hinge side) when it is all the way open. On the non-hinge side, the brackets work the same, but you don't need to worry about sliding them into position. The carriage bolt is inserted from the front of the baffle through the slot and screws into the 2 x 6 section to pull the brackets (and therefore the baffle) into the doorway trim. It consists of 2 sections shown screwed together in the picture below. All threaded hardware in this section is 3/8".

The "back" section is a 6" long piece of 2 x 6 with a 3.5" L-bracket screwed to it. I used blue painter's tape wrapped several times around the end of the bracket to protect the doorway trim when the bracket pulls against it. I drilled a 1" diameter hole 4" deep into the end of the 2 x 6 and drilled a 1/2" hole through the remaining 2". Then I installed a 3/8" T-nut into the 4" deep hole. This allows the carriage bolt to reach the T-nut only 2" into the assembly.

The "front" section is a 7" long 3/8" carriage bolt with a wing nut screwed all the way tight against the head and a jam nut locking it in place. This can be replaced by any type of thumb screw type fastener, but I had trouble finding a one-piece option that was this length and diameter. Then I used a 1.5" diameter fender washer and a 3" diameter by 3/4" thick particle board "washer" to completely cover the slot when in position.
