SStS TM-3 MOTOR CASING
I started on the TM-3 motor tube this morning. It absolutely dwarfs my lathe, but being aluminum instead of steel it's much easier to work with than the previous DSS motor cases that I've worked on. I only need to index the retaining screw locations and true the ends. I should be able to finish this tonight, then I'll get to work on the other half of the TR-1 nozzle. With approximately 90 lbs of propellant this motor should produce a total impulse that fits it into a P-Class designation.
