More fitting, tedious details. Drill, debur, re-check, and re-read plans. Fabricating the conical corner inserts and getting a good fit - tedious.
Lots of details, but the essence is to fabricate the baffles in four major sections. Each section is supposed to be removable intact. Pretty tight fit but seems to be working.
Details like getting the flush rivet on the correct side of the panel (thus countersinking on the correct side - important).
