@ataxian, thank you for your nice reply concerning ataxia. I have since googled & read up on this disease. And sincerely appreciate the clear picture of the pieces broken down.
@Baron23, I didn't know that there was a disease called ataxia. I just was curious how @ataxia chose his username as most everyone's name has some personal meaning to them. In the little time that I've known ataxian I was thinking that it had to be rooted in something philosophical or astronomical. So, thank you, now I know & I've learned something from the both of you.
@pxl_jockey, no, I'm glad you posted because I was gonna ask if the 2 flared rims on the mp were ornamental or functional since Baron didn't address this. But don't know what you mean by, "If you double-click the tiny pic in your post above ataxian's you can see the first joint is the female of the ashcatcher."
1st joint of
what piece?

@GreenHopper, I need you to annotate the pic with arrows & circles.

I'm now starting to learn about wps & wpas. So the adaptor to the immediate right of the wp is known as a diffusing downspout?
