I have a few more questions about rust. Do you remove the rust from the interior of the pipe as well? Do you paint the inside as well? The OSPHO ButchM mentions seems like an interesting product. Is it safe to use on the inside as well? I'm not sure if it will react to the heat and seep into the items being smoked. There is so much to know to start one of these builds.
Does the drip pan in an RF build doulble as a baffle to push the heat down once it enters the main chamber or should you use another plate to do this? Will there be room in a 20'' pipe to have two levels of cooking grates, or will only be room for one. I think I read the cooking grate should be 4'' from the heat baffle.
Thanks for answering all of my questions, guys. This is really a great forum.
