One of the features of Open Rocket, is the ability to print the nose cone profile. As it turns out, the Estes cone is closer than I thought. I printed it on card stock, then used it as a guide as I slowly shaped the cone. As with cones I've turned before before, final shaping was done with 60 and 120 grit sandpaper. Then finally, I cut the tip off.
I've done that before too! Usually I make a negative half pattern that follows the outside of the shoulder and ogive (it sits on top the cone being turned), if I can find one I will post a photo (may or may not be able to find them after the move a few months ago).
