I riveted the blast tube flanges on to the baffles along with some stainless steel mesh to keep out the bugs and debris. This is the one on the front right baffles that sends cooling air to the alternator.
Here is the underside of this flange. There is high-temp RTV between the flange and baffles to seal any air leaks.
I also riveted one of the left rear baffle to send cooling air to the magneto.
Here’s the back side of this flange.
Here’s where this fits in relation to the magneto. This duct is obviously too long, but it shows the routing to the magneto. I’ll anchor the other end with an adel clamp anchored to the upper oil line.
