Actually I've been working on much more than the baffling but since the cowling and the baffling work together to keep the engine cool its a bit of a mixed bag of tricks. I'm paying extra attention to the baffling because these tightly cowled RV's run hot and I don't want to spend time chasing cooling leaks after I start flying.
|This is the inside of the cowling with the glass flange laid up and epoxy curing.
|This is a picture of the inside of the same baffle piece. Here you can see the small air gap that will allow air flow past the smooth portion of the cylinder wall...see below.
|Here is the back side of the #5 cylinder. You can easily see the small area where there are no cooling fins.
|And here is the final product after cutting the improperly shaped baffle material off and attaching the correct shaped piece. Much better fit.
|I had to add this picture as well. My good friend Ben has been helping me with a few tasks. In this case he is back-riveting the stiffeners to the wing root top skin.
|Finally, this is the left side air inlet with the prop governor issue I mentioned earlier.
