Could someone please tell me how a Grand Slam fitment is secured in the stem's tenon? I am cleaning up a Grand Slam in which the fitment is about 30 degrees off of correct alignment (looking at the fitment from the bowl end the holes at the midpoint of the fitment sit at roughly eleven and five o'clock rather than twelve and six o' clock). I doubt this misalignment will negatively affect smoking, but the fastidious part of me wants to correct the defect. My desire to fix the problem is not, however, strong enough to make me risk breaking the tenon. If the fitment threads into the tenon, I will leave well enough alone. If the fitment is simply pressed in, I will probably try to turn the fitment to proper alignment. Any information will be much appreciated.
