A little more shaping tonight, using the 14 inch cutoff wheel to cut radius guide marks into the foam worked pretty well for shaping the lower cowl exit. Pretty easy to eyeball a center for the cut and then measure from the cut off wheel to the cowling to keep things concentric. Kinda odd that I actually had a 14 inch concrete cutoff wheel laying around the shop from a totally different project.



You can see parts of the guide marks cut into the foam, basically just sand the grooves to the same depth or gently sand the grooves flush and it shapes itself.





A paper towel roll is close to the same dimensions of the lower firewall bump/radius, trying to visualize how I want these curves to intersect.
