Mainly because I get my wood whole and chop it/chip it down with a hatchet. I live in an area that is ripe with cherry, apples, and apricot as well as tons of hardwood. I'm still burning through a few big bark free cuts of a 100 yr old oak tree. This thing would take two grown men stretching arms to lock hands around it.
With the amaze-n, I have to buy pellets as I don't have easy access to sawdust. If I want a specialty wood I can't get here, I have to buy wood chips anyway, for hot smoking. Plus, and I know this is a cosmetic thing, but I find it's really hard-if not impossible-to get a good smoke ring without incorporating charcoal somehow. With this device I can put in charcoal and bigger chunks of wood.
I have no problem drilling a 7/8" hole through the side, I'm just hoping someone else butchered one... There is a wire for the meat thermometer on that side as well as the smoker temp sensor. I would think those came in from the back and I'd be safe, but the series I have would burn those wires I mentioned and some people have converted them for other usage.
Maybe I'll just do it like a dissection. Run a 7/8" hole saw and barely cut through each layer, rather than use a drill or spade bit.
