2. Construction Timeline
By Thursday, June 22: OpenRocket design decisions, deliver PDR in class, build rocket cradle, modify nosecone (add eyebolt), collect more parts
By Friday, June 23: CAD and fabricate all wooden parts and G10 fins, cut airframe to length, cut/borrow recovery harness (2 sections)
Monday, June 25: cut fin slots, sand parts, prepare centering rings, epoxy upper centering ring (first to mmt then, once dry, inside airframe)
Tuesday, June 26: begin epoxy of external fin fillets (might take 2 days), assemble av-bay structure), study av-bay wiring (details given in class)
Wednesday, June 27: when all external epoxy fillets are dry add internal epoxy fillets (all at once), lower rail button, and lower centering ring
Thursday, June 28: completely wire av-bay, finish recovery harness and flame protectors, make wood block for camera pod
Friday, June 29 (and weekend if need be): catch up on construction if behind
Wednesday, July 5: appointment with Prof. Flaten to “check-in” with finished (unpainted) rocket, add rivets and shear pins, work on FRR slides
Thursday, July 6: deliver FRR in class, test avionics and do ejection charge test
Friday, July 7: paint rocket – will need to let paint dry between coats (if any)
