I am trying a new method for motor retention. In the photo are the parts. Regarding my question, the important parts are the 2 Aerotech 38mm reload aft closures on the left (old and new style), and the silver disc. The disk fits over the aft closure, and the nozzle fits through the hole in the disk.
But that's the question: will the nozzle fit through the hole? The diameter of the disk hole is larger than the diameter of the hole in either aft closure. Therefore, the only way that the nozzle wouldn't fit would be if the nozzle flared outward after it passes through the aft closure, downward (away from the motor). I have never seen a motor like that: the nozzle has always come straight out from the aft closure like a cylinder.
The silver metal disk is really a pain in the *** to grind, so I would like to stop. But if any nozzles flare outward, I would need to grind the hole bigger. Has anyone ever seen a 38mm motor nozzle that flares outward? In fact, now that I think about it, this would seem impossible because you would never be able to get the nozzle through the aft closure from either direction. But maybe there's something surprising that I don't know about. Can anyone confirm that my sense of things is true for all 38mm motors?
Thanks,
