Thanks to all here for your input. I tested this unit over the weekend and it all worked pretty flawless on the first try. Here are a few pictures from start to finish on the build.
The start of by Cook Chamber. Made with re-used 3" insulated cooler panels.
Cook chamber is basically done here expect for the RF Baffle plate.
This is the Fire Box. Made with 3/16" plate. Interior grating is about 4" above the bottom.
Here is one of the SS stands that hold by cooking trays.
This 1/4" SS Mesh is what i used for my cooking trays..
This angle will support the RF Baffle plate in the Cook Chamber.
Here is the final product. I used a SS plenum style chimney with about 6" extended into the CC. To season the smoker i lit some charcoal in the FB and placed a couple pieces of maple and oak wood on top to get some flame going. in 15 min i was over 200F in the CC. I closed the damper on the chimney to see if it would heat up faster, and it did. Once it got to 260F I dampened upper intake and lower intake in FB to virtually closed and opened the chimney damper a bit. It held at about 240 - 260F for over 3 hours with the initial bit of Fuel i put in the FB. I know it doesn't look as pretty as some, but i can't be happier with how the initial run went...
