The absolute easiest way is to spend some time at hobbytown USA at the rocketry section. They sell rocket bodies and noses as spare parts. Find the right shape and length, then make all the fins out of polyply or similar. My problem is always finding a nose that looks like ordnance. You obviously have a lathe of some sort, so shaping one up should be easy.
That's it, I need to find myself a small hobby lathe!

David. Chek out the combo lath and mill at Harbor. Will make about anything for the scale stuff we do. Get a one time 25% off coupon and carry it home. I used a smaller one (unimat) for years on small gun parts even after having full size lathe and mills.
