I started drilling the plenum mounting angles tonight. I made it around halfway around the baffles before getting frustrated with the ones along the front of the engine. These have the most curvature of any of the baffles and I kept splitting the metal with the stretcher. I’ll probably end up having to section those angles to get them to curve that much. Here’s the angles around the oil cooler bump out.
There will be a small gap here where the left and right sides of the aft wall join. The plenum will span this and the gap should be tiny if not nonexistent.
Here’s the aft right side of the engine. All of the corners are mitered, and I’ll install a nutplate that spans the gap in the corner to further tie these pieces together.
