I have looked at the mod, understand it completely and have bought everything I need. But since my analog doesn't have the "chip adding hole" in the side of the smoker I am leery of hole sawing through without seeing if anyone else has done this. Pics attached of inside and as you can see no hole to work with.
I have a 3" bi metal hole saw bit for a drill and am ready to tackle the upgrade. The side walls are double walled and I am wondering what kind of insulation there is inside them?
Any help would be greatly appreciated with this project.
