We used something like that (only bigger) on our 300mm rocket. We cut off the
tip to match our throat and welded in place on a plate that was then bolted to
the bulkhead, That would be something you'd have to figure out how to do with
this small of a motor.

Tell me what you think of this find: (see attached photos) It's a stainless
steel nozzle disguised as a Wilton's cake-decorating tip. Found at my local
craft store for 99 cents. It's .714" wide at the base, 1.24" high from base to
apex. 15 degree angle from center axis. Steel is .01 thick. Since it is so
smooth, I plan on using it to mold nozzles instead of turning a wooden mold on
my lathe. But what do you think of the possibility of using it in a small motor?

Thanks for your help, I will do all the things mentioned to keep that throat
open and see what happens. I too like graphite for nozzles, if the other
suggestions work, i sure would like to use them.
Keep us posted--I for one would really like to know how things turn out.
