Ok thanks for your replies. I like my meat with lots of smoke and that is why I am wanting to get the tube working in it. With that I know I can get a good 3-4 hours of constant tb smoke. I may try using a fire block and separate the charcoal and tube as I think the charcoal stared the tube of oxygen when using the menion type method.
From looking at the charcoal grate it looks like the some of pellets would fall through the grate if I scattered them throughout the charcoal. May could use some expanded metal though.
I may try the foil pouch idea but that's why I got the tube for the propane was to get rid of using foil.
I just don't want 100 pounds of pellets to go to waste.
I guess a little trial and error.
