Default Balsa nose cone construction

I was hoping someone in this section could help me out on this one. To start off, I am scratch building a 60 size twin engine plane. It will be powered by 2 - 36 engines. The fuse will have a nose wheel and a bulkhead directly in front of the nose retract. My dimensions of the bulkhead are right about 4" tall by 3" wide. The nose has been drawn up elliptical both directions and will end just about 4" in front of the bulkhead.

And now now for the million dollar question. How do most builders construct the nose cone for a plane like this.

My original idea was to make a ply template of the bulkhead and glue a large balsa block 3 x 4 x 4 on the template. Drill a hole through the center of it and place a bolt or dowel through it and then chuck it in the lathe and turn and sand it down from the rectangle end transitioning to the round nose. I would then hog out all the balsa from inside the cone until I had about 1/4" thickness. I would then cut it off the template and sand and glue it to the bulkhead. Finally I would Sand it to flow into the fuse.

Does this his sound about right? Any tips our other methods out there?

thanks for any comments you may have.
