Sand the cut top smooth and flat. Remember I mentioned the first scored circumference line was cut slightly above the 4.6" length? When sanding the top flat, you are getting closer to the final length.
With a fine point pen, find the center and mark with a dot.
This is critical for a centered tip in the final shape. Take your time, measure twice from different sides to make sure of the center.
Start making small chip cuts using the center point as a guide. Keep the flat top area round as you make the chip cuts.
Keep cutting away until you get about 1/16" away from the center point mark.
Rough sand the nose cone using 100 grit on a block.
Concentrate on the final contour, check the nose cone profile print often.
