Diaphragm call build along...

[Lonehowl]

I made this build a long tutorial for a couple buddies, but decided to put it up on my site. Its not very well done, but served the purpose. Hastily made but it is what it is. Thought Id share here.

I use them a lot, but I've never really put any thought into how the calls were made. Very interesting. Thanks Mark.
