A look at the results and then a look at the lathe objects revealed
your scaling problem. The aspect ratio you choose for width vs. height
was off a factor 2:1. I basicaly increased the numbers in the right column
by twice their value for added height and adjusted the translation of the
projectile and it came a lot closer to what it should look like. This
was all quick shot in the dark changes and you will need to correct
a couple of niggly little steps I left in the code below before it will
look good.
Sorry about the non indented script. I Can Not read a lathe or any other type
of multi point object withouth having it in columns. It adds clarity
to my perseption.
