Making an executive decision here.......you're always on the Agenda! That's good to know bout the Rm9. I haven't had much leaking with the derringer clone I have since using the o ring, only once I think. Most of my leaking issues have been resolved, but it was making me nuts the first couple of months. Really good to know about the Rm9. Will save up and try one. The nuppin is really hard for me to build, always takes me a lot of time and I'm sure I don't do it well, but it's just the best flavor and perfect air for me so it's worth it. But wish I could find a good build video or get someone in the hangout that is really good at it to help me with the mechanics of it to do it better. I'm sure there is an easier way than how I do it. lol Appreciate you chimin in bout the Rm9
Here's how I've figured it out to make it easier..
Put the low side in the post first then push the high side down into the hole and tighten it down. Then possition the coil right up against the side of the deck so it will be right on the air hole and then tighten up the center post screw. Check height of coil to make sure it's either centered to the air hole or slightly above the center of the hole by holding the top lid against the bottom edge of the nuppin.
Excuse my cheesy quick drawing done on the phone with my pen hehe.. actually I'm a pretty good drawer back in the day.. been years since I've drawn anything.
