[SML] Wiggle wood for a cannon?

[Jon Lagerquist]

Not that using a 3D model to find the shape is in anyway a bad way to do 
this, but the shape is simple enough that you should be able to 
accurately draft it on a napkin at the pizza parlor. Two radii and a 
length gives you the cone. The circumference of the larger diameter 
determines the number of gores. The height of the cone and the larger 
diameter (and Pythagoras) gives you the center point for the arcs on the 
large and small ends.

Once you like the shape and the diameters are appropriate, you can use that heavy paper as a template for laying out on the bendy board.  Remember that bending lauan can be had with the bend across the width or along the width.  Those half-round shapes wrapping the front of the barrel and at the "breech" in the image are good candidates for split Ethafoam backer rod or split pool noodles.
