Find a 3:1 ogive cone for a 4" tube. Resembling the Alpha cone, it is a popular shape. Glue a 3" coupler to the base of the cone.

Make a cardstock shroud reinforced by fiberglassing to form the aft part if the warhead "cone."

You may have to grind or sand the base of the cone some to get it to fit into the shroud.

It is well past time to Drill, Baby, Drill!

If your June, July, August and September was like this, you might just hate summer too...

Please unload your question before you ask it unless you have a concealed harry permit.

Give a man a rocket and he will fly for a day; teach him to build and he will spend the rest of his days sanding...
