Been working on the cowling for about two weeks. Lots of sanding, put it on, take it off, etc. Have most of the surfaces pretty well fitted. Only problem is at the spinner end (front face). My cowl halves do not oppose well at the front face. The lower cowl front face is offset in such a way the the top cowl overlaps at the spinner end front face (the circle) and I cannot see any way to sand the flange to allow the two to mate. The lower cowl half is actually set back so that the upper cowl has a lip over the lower cowl at the circle. Have others built up the front face of the lower cowl spinner end front face and if so what have you used? Photos would be really helpful.
