Thanks for clarifying, Jim. Now I understand.
I was concerned about the dividers coming loose so when I first drilled the hole into the cavity and divider from the water jacket, I used the bit size required to tap a 10/24 hole. Then I removed the divider and tapped it for that size. (I've slept since doing this, but I think that is the size I used. I don't think anything bigger would be required.) I put JB Weld in that tapped hole and around the base of the button head to seal everything up and screwed it all together. I don't think it is coming loose.
Michael, sorry, I didn't take any pics of what the baffles wound up looking like. But, these are what I started with,

Like I said, you have to use a lot of Zen and hold your tongue just right as you feel your way along grinding and shaping those things to get them in place. Hope that makes sense.
