| One of the most frequent questions I get is, "How do you align your fins?" I've cut fin templates out of foam core and the results were extraordinary. It's also a lot of work. The question is, is there an easier way? I have a technique that is fairly simple, has minimal hardware requirements and provides pretty decent results. |

Draw a line on the outside airframe 180 degrees from each fin slot to be aligned using a straight edge. (We'll talk about how find that point on a three fin rocket in a future article.) Apply your adhesive of choice to the root edge of the fin. I typically tack the fins with a couple of drops of CA. Tip : On Quantum Tube you can use a fine point Sharpie to draw you lines. When you're finished, you can wipe the lines away with alcohol. |
 |
Facing the airframe opposite of the fin to be aligned, place the fin in the fin slot. Close one eye and visually align the three elements in a straight line.
Repeat with the other fins. |

| Tip: It helps to place dots at the base of the airframe under each of the fin slots for additional visual reference points. Additional Resources |
