I  made good progress on the TR-1 nozzle this weekend.   The two pieces fit together nicely.  I'm still tempted to take some weight out of the nozzle, I think I could get a nearly half a pound of weight out of it. I'll probably hold off until after the initial static test before trying to reduce the nozzle mass.  I'm currently making some modifications to the DSS motor nozzle for the Sugar Shot to Space project.  Once that's completed, I'll finish the TR- 1 nozzle and get to work on the rest of the motor.

Nice machining, Randy. Looks very slick.

Are you putting some kind of seal between the two parts?

Thanks Ben. It's been nice to get a some serious time at the lathe again, it's been too long. I've thought about using something to seal the two parts but I'm not sure it's necessary. McMaster-Carr has some gasket sealing silicate adhesive that's rated to 2000 degrees and doesn't cost a lot, but I probably won't use anything for the initial static test and see how it goes.
