I have a MES 40 and a smokey mountain smoker. The vent on the MES is on the side and the vent on the Smokey mountain is on the top. Could I use metal dryer type tube to put smoke to the SM smoker to make a cold smoker? If so how many feet of duct do you think I would need to be sure the smoke is cold enough? I thought I would first go up with the duct a couple of feet and then back down to the second smoker (heat rises). I might have to drill a 3" ? hole near the bottom of the smokey mountain since I doubt the smoke would drop down into the second smoker....maybe a small fan to push the smoke there? or does the second smoker have to be higher than the MES? Thought by doing this I could smoke meat in the MES and cold smoke other things at the same time in the other.
