6 hrs, 52 rivets
Finish riveting major portion of baffles, except the conical ramps. These might need a bit more clearance, and may have to be redone. Start installing blast tubes. Got one in the wrong place, will have to redo that.
Now have 4 large parts that make up the baffle system. Still a bit more tweaking, such as the remaining blast tubes, the bottom tensioning pins, and the air seal material.
Soon the baffles will be DONE. I think they might work right.
