I have a question about the pellet tube smoke generators that Todd makes. What is the outside diameter of the tube? And are all the tubes the same diameter? Reason I ask is I'm wondering if one would fit in my smoke chip tray on my Weber Summit grill. It sure would make using pellets in that very easy. Yeah, I know the easy answer is just set it on the grate over an unlit burner and I have done this with my pellet tray. But I'm thinking it would work better inside the chip holder as it would shield the tube from the bulk of the burner heat during a high heat grill and still give good oxygen flow from beneath the entire tray length. I'm thinking a 6" tube model might work if it would fit (can't see a high heat grill session running for anywhere near 2 hours except on the rotisserie perhaps? Plus the grill is to air/smoke leaky for a cold smoke).
