Started putting in the internal bracing yesterday, nail, glue, wipe excess. We found that we were 1/16" off on the internal volume, we'll see what that does with the sound.
Fitting in the bracing for the ports, ready to glue. The flat piece in front is a removable port cover. You can use the cab with or without it depending on your preference.
Incidentally my cousin (the carpenter) called me this morning to tell me that he was going to work on it. He has a Gov't job, and home at 10:00 a.m.
