So today I finally figured out how to add lit charcoal to my 22.5 WSM in the middle of a cook without having to lift up the middle section. I had some round flashing in my basement from adding a return air vent in the basement. I opened my access door put the flashing in the door and under the water pan and poured my hot coals down the chute. It was so easy and my chimney fit right in the flashing so no chance of dropping hot coals on my toes. Would be interested in what the rest of you do.
