And that is my problem, i.e. ability to inhale, while bottom of cloud (bamboo) is blocked. And the result is I'm getting diluted clouds which is what drew my attention to this problem in the first place.
Upon further examination I'm finding that the only point of contact between the working end of the bamboo (the male joint) and the female end of my glass pieces is at the larger (18mm) end of the male taper. The small end of the male taper of the bamboo is not touching anything when inserted into my glass pieces, hence the wobble. What I hate about this (besides the leakage) is that the stresses seen in a single point of contact (the circumference of the large end of the male joint) is much worse at that single point of contact than if the stresses were distributed evenly along the entire length of the tapered joint like it should be.
Here's a quick drawing I made to illustrate the problem:
All I can say that I didn't have this issue with my original Cloud. Both the Ion and Evolver fit it perfectly. The fact that both the Ion
and Evolver fit so badly on my new Cloud+ pretty much says that the male joint on this new bamboo is at fault. The only other piece of glass I can test with is my 18mm female slide stand which also wobbles when placed on the Cloud+.
