I actually finished the motor casing prior to the nozzle, but here are the two pieces together. It was a conscience decision to complete the casing first so that I could get the most accurate measurement of the ID before starting on the nozzle. The ID in this case ended up being very close to the spec. and the nozzles actual OD ended up being 1.606". I will probably make the bulkhead a few "thou" smaller in diameter to make it a bit easier to install and uninstall in the motor.
