John's 2.75X Alpha & Kellogg
January 9, 2005This is John Weiser's (age 12) space related project. One of the options was to build a scratch built rocket and compare it to a NASA type rocket. John had been talking about doing upscales of his Estes Alpha Kellogg so we found some 2.56" phenolic tube and did the first one. He decided to show a HPR motor and the only one I had was a J570 which he thought was very cool - although too large for this project. He has plast grains and the case for a 38/360 to demo at school. John did some of every step except cutting out the fins on the bandsaw including turning the nose cone.
