Seems as though the last design I used for my motor's Nozzles was a little poor (to say the least).
I've been trying to find a quick and easy way to make a good nozzles that doesn't require cutting steel on a lathe (which I don't have)...
These were made with a PVC Bushing, a washer, and Hydraulic Cement. Perhaps the cement did not have enough time to setup before it was fired (i waited atleast 24 hours).
It's good that the throat (the washer) held up ok, but I definetely need to get a better design going to get reliable nozzles...
Here's the "autopsy" pictures from my last motors (static test video here: http://www.youtube.com/watch?v=55thy1WTh48 )
