Hi All, I have had my CharBroil Offset 820 for about a week now just sitting in the box. Due to other commitments I have not been able to get it put together and it is my hope to get a start on it this weekend. I have picked up everything that I could get my hands on for the mods that I want to do as I put it together. Here is what I have planned: High temp red silicone from 3M to seal all screws, the space between the firebox and the main chamber, around the stack, and anything else that needs it. Non-galvanized aluminum flashing to extend the stack to the grate held in via friction. I will also use a length of this to heighten the stack and improve the draw. I have some steel mesh to create a charcoal box, not sure if it is suitable or not as it has a black coating on it. (Chime in if you recognize this as being an issue!) 2 firebricks wrapped in heavy duty tinfoil to line the bottom of the main chamber. I am going to use the aluminum flashing or a cookie sheet to create a baffle and tuning plates as well. I searched high and low for the right steel for the job to no avail. If and when I do find it at least I will have templates created with the flashing! I read on another forum about someone that used flashing for the tuning plates as well and they indicated that it was helpful in evening out the temperatures. Re-curve the main chamber door as there appears to be some play at the lower edge of the door. I will try to bend it by putting a marker under the lid towards the top. Failing this I may try either fireplace barrier ribbon or the oil spray with the 3M silicone. Water or sand pan by the firebox opening. I may or may not cover the charcoal grate from the main chamber with aluminum foil. Hopefully all of that will help to seal the smoker well and allow for decent even temperatures. I will take pics as I go and post them up here. As always, I am open to suggestions! Here is what I am starting with.
