More destruction, man I was so proud of those ramps. I used foam/glass to continue the spinner curve of the cowling onto inlet ramps so the black baffle material had a nice smooth transition to push against. I didn't have the heart to throw them away...
The top cowling is cleaned up and block sanded, I never smoothed the surface originally and just roughed it up and covered it with epoxy. I'm thinking of using the top cowling as a mold for making a plenum but it's going to take some work first. I would rather build the plenum over the existing baffling, but I can work with the top cowling at home in a semi-heated garage (and in the house next to the woodstove when the wife is at work!). Here's a pic before the first thin coat of filler/micro.
