I finally got around to assembling the Smoke Vault 24 that I ordered a couple of weeks back. Everything went well until I put the door on. It did not align with the right edge of the smoker. There was a gap between the door and the right upper edge of the smoker. OK...so I shimmed the bottom edge of the smoker so that when the door is shut, the gap is lessened, but I still have a 1/8 inch gap on the upper right edge. In fact when i peek through the to vent hole, I can see light streaming through. Any other fix I can try to close the 1/8 inch gap? I'm worried about heat loss, although I do not know how much gap that size would affect heat.
