I'll be doing some modifications to my New Braunfels smoker soon -- flat stove rope gaskets on the doors so it seals against the wind better, and another internal baffle to keep the heat moving closer to the meat instead of up by the lid.

While reasearching this at the BBQ FAQ [url=http://www.bbq-porch.org/faq/:b215f]http://www.bbq-porch.org/faq/[/url:b215f] I thought that this might be a good link to post here in this thread! Lots of info on building your own equipment, and smoker modifications. Beginner's tips, expert's theories, etc.

My next project, I believe, will be a vertical cold smoker. Just replaced my old kitchen range with a new one, and was looking at the old one's enemal inside the oven, the broiler pan that looks like it will hold charcoal, lots of space for racks....

Another tidbit from there -- anyone who's tried to do real BBQ in a propane grill knows the problem -- even with only one burner on low, it gets too hot. I don't ever go above 240 F. You can convert one of your burners over to a lower-power variety, and with this mod your standard grill can be used as a propane smoker at low temps.......groovy!
