Brad assisted me with this task this evening. I had to take about 1/8" off the front of the bottom cowl for proper clearance for the spinner. Previously I had added about four layers of fiberglass. I sanded down to the lines that Brad had drawn a few days ago. This took it down to the first of the new flberglass layers. Because of this, I added another four layers for fiberglass this evening and then added peel ply.
The front still needs to have the edges contoured and all the holes filled.
