The evaporation chamber ended up getting stuck on the atty dock. Removing the parts required 2 x sets of channel locks; which scored the shit out of both parts! I ended up taking a Dremel (w/fine grind wheel) to the damaged parts. Looks really good, but I still need to polish them. I could have just heated the evap chamber using a butane torch, but I didn't think of that until after, of course.
The machining tolerances are so is tight, that I'm not convinced that the 10x1.5 o-ring is even needed. Since the liquid is not under pressure, I can't imagine liquid making it past the base. I used some food-grade lube on the threads this time, so I shouldn't run into any more locking issues.
So far, I think I prefer the V4 over the V5. I like the more restrictive action of the V4... Great MTL hitter! I also like the easier 1/2 turn JFC cutoff as well. I ordered a sub-Ohm kit, but I'm not sure I'll even use it. I may use the high-heat insulator, and leave the center post stock. V4 for MTL - V5 for DTL. If you're someone who loves to tinker, the V4 is a kick! I love the "old school" multi-part format of the V4. Reminds me of older cars that you could actually work on.
