New member here. I have an older New Braunfel offset grill/smoker. Not sure of the model number. I've never used it for smoking but would like to try. Before I begin, I'd like to upgrade a few parts and do a few mods. Keep in mind I do not weld, etc. It's still in decent shape although I will sand a few spots here and there and throw some paint on it. In no particular order, here are the things I'd like to do. Build a charcoal box. Not sure what size is recommended or will fit. Looking online, I see some that are 6" tall, 12" long, and 12" wide. Seems that would be adequate?? Seal the lid, etc. When I grill, a decent amount of smoke escapes. I'll pay attention to exactly where the next time but I'm sure alot of it is around the lid. What is recommended to seal it better? I'd really like to replace the grates. It has the standard cheaper wire type grates. I wouldn't mind having porcelain coated or whatever is recommended. New Braunfel is no long manufacturing. Is there a "custom" type place that will make them to fit? There's two of them that are ~13.5" x 15.75" or so. Seems someone would maybe have a universal one that might work???? Baffle or whatever it's called to direct the heat/smoke from the firebox evenly throughout the main chamber. I'm lost on this one. If there's an easy way of making this myself, that would be great. Thermometer(s) for the main chamber. I presume it would be best to have one on each side of the main chamber. I'm guessing you would just drill a hole out in the lid and use some type of high temp adhesive to secure it into the lid??? If so, is there a decent, inexpensive model to get? I'm sure I have more questions but I think this might get me on the right track. So, any help with any of my questions is greatly appreciated.
