After a few weeks of getting input from this forum and homeroasters.org and much pondering I came up with what I (humbly) think was a great solution.
I posted the info on homeroasters.org http://www.homeroasters.org/php/forum/v ... post_53557.
Figured I'd put a notice here in case someone's thinking of doing the mod.

That looks great and all off the shelf parts...
