Here are some pictures of my progress. I ended up using my table saw to cut the radiator mostly. You will see how I used my adjustable angle finder to set and determine, the miter angle needed. It just so happens to be 22.5 degrees, the typical octagon miter angle. That is where the table saw is very valuable. I am working from the center out, and top down, scribing in to fit on the outer sides and bottom. This helps create nice tight joints. I have not glued anything in place yet. Once I have all of the added wood I need on the cowl, and have it all cleaned up like I like, I will start to glue in the radiator pieces. When cutting, this material tends to melt. So it will be necessary to clean some of this burr material to be cleaned out of the holes. Overall, this is going very well, and is going to make a huge difference in the finished look of the model. Also note, that is a brand new DLE 55 that was installed a few days ago. I needed to get that in place, before I did this work on the cowl.
