We've been busy this week making good progress on The Shadow. We now have a new set of fin guides that will be used to align the fins. We made a new coupler mandrel and have made a number of fiberglass couplers for joining tubes. We also started working on the business end of the rocket today and machined the nozzle and the nozzle seat it will sit on. We are having to build a completely new launcher for this rocket to handle the higher pressures.
