The summer has been busy so there hasn't been a lot of Rocketry getting done. I have been working on a test rig for the SStS program that will be used to test tensile strength of propellant which will have varies additives designed to increase its strength. This is a pretty interesting idea and the results could help open up some new possabilites for sugar based propellants. The TR-1 rocket motor hasn't moved forward much, but I have gotten the 4" EMT (seen above) for the motor casing. I'm hoping to be able to start construction of that motor in earnest soon.
