I have a question, about sealing the firebox on the OKJ Highlander. I first tried the felt gasket but it was burning out in spots during my initial run. The temps held good in the cooking barrel but smoke was escaping out of some spots on the fire box cover. I scraped off the felt and put a bead of hi-temp silicone gasket sealer around it. But the lid doesn't fit tight against the silicone. What's the right way to apply the gasket material to get an even seal?
Also another question, how important is it to seal the exhaust tube? At that point the heat and smoke has already made its way through the chamber. Other than the looks what does it matter if some of the smoke and heat escapes though the joint instead of out the end?
Thanks to everyone on this forum for sharing their ideas. It made things easy to follow to modify my smoker.
