2.375" Motor, Nozzle Update

I pretty much finished the nozzle. I used a parting tool to cut the o-ring groove and the groove where the insulation fits into. I then parted it off, flipped it, and cut the convergent side. I still need to drill and tap the retaining screw holes and I'm planning on adding some "gun blue" or similar rust resistant finish.
