This rocket be inspired by t' fins on an Apogee Skonk Wulf which kind o' look like shark fins.  That lead me t' buildin' a hammerhead nose cone. 

I used a couple o' techniques on this rocket that were new t' me:  Paperin' fins and Through T' Wall (TTW) fins. 

T' fins are 1/8" balsa papered usin' Elmer's White Glue and 61 lb Staples double sided matte paper. 

T' nose cone I turned on me wood lathe from a pine 4 x 4.  T' hammer portion is made from a pine 1 x 3.   T' hammer is a tenon fit into t' nose cone affixed usin' Gorilla Wood Glue.   There's quite a nit o' surface area for t' glue, so it's quite strong.

This rocket needs a lot o' nose weight.  I ended up usin' a 3/4" Machine Screw that threads into t' bore o' t' nose cone.    

Power is via a composite 29mm motor, another 1st for me.  Parachute is 28" rip stop nylon. 

Stability calculated usin' Open Rocket software and verified via a swin' test.
