Good morning, Jam thanks for thinking of me and my work. I have never seen the vapor genie, this is a first for me. I would like to accommodate you but am unable to take on anything out of what I already do. When I say slammed, that's what I am! I am damn near all out of dugouts, still spinning vapor stems just trying to keep up. I have a big deal I am working on in the European market that is looking awful promising. Seems there is a big demand for wooden solo stems there. I hope you understand Jam and thank you again for the suggestion.
Arrr, glad you got the stem and hope by now you have had time to enjoy it. This inside of the stem is what it is, I have 5/8" SS seamless tubing turned down to the OD I need then have the slots milled. You are not supposed to be able to turn the pin or really not do anything to it. The pin is installed to ensure there is no separation between the wood and the SS. As far as removing the screen simply pushing something like a small skewer or something similar down through the mouthpiece end and push the screen out. Another screen can easily be swapped out and seated back within the bushing. I hope this helps and wish you alota good times with the stem.
