Drawing out where this hatch goes meant getting a little firmer on how I am going to do this nose thing. A few hours went in just drawing out the position, seems crazy right?.

Eventually I committed as you see in pic 2. The fine saws came out and I again hot glued rulers to the lines to use as straight edges. Its slow going but really works well to get an exact cut.

Pic 3 shows the confusion at the rear of the cutout, or lets just say it needs a little leveling out.

Draw final lines
