After destroying another heat probe by accidentally dropping the door on my lang I got tired of placing the probes through the door. I took some bolts to my metal lathe and hollowed them out. The next step I was going to do would be to drill 3 holes spaces evenly in the back wall of the cooker. I was then going to put in the bolts and weld some nuts into the interior of the cooking chamber to hold the bolts in place but also allow the hollowed bolts to be removed and replaced with solid ones to reduce heat loss. What I am unsure about is heat loss from the extra holes and weather I should weld the nuts in place or use a high heal silicone to form a more air tight seal. I am hoping that some of you guys that have more experience tinkering will weigh in.
