I'm hoping someone can help me out here. I've been using the double-barrel I built last summer since then without incident -- and I've been turning out food that's been earning unbelievable raves. One problem, though.

I cut the door for the smoker out of a third barrel, drilled holes in the piece I cut out to make the hole and laid it inside the cooking chamber to act as a baffle to distribute heat. Works great, but for the fact that drippings from whatever's cooking fall onto the baffle, run down to the wall of the cook chamber (coming from a barrel, the baffle is convex) down the side and into the flues. From there, it escapes through the seams between the vent collars and the lower barrel and runs over the outside of the fire chamber. Doesn't affect the quality of the food, but it makes one hell of a mess.

I've sealed all the seams with hi-temp sealant and used furnace cement over that, to no avail. The furnace cement is actually flaking off, which I don't understand at all since I never run the cooker over 300 degrees, and then only accidentally.

Any thoughts on how I can keep this from happening?

Thanks.

Weld the seams, maybe.

Not really an option. It's beyond my capabilities. The metal on the drum is also pretty thin; I'd be concerned about damaging it.

What about lining the bottom of the smoker with those disposable aluminum drip pans? That way the fat drippings fall into a pan and at the end of the cook you can just either empty the pan or throw it away. I realize this doesn't fix the leak in your smoker, but it might make life easier.

To heck with the leak, buy a $10 vinyl grill pad with raised edges and put it under your pit.

We may have found our winner here. Any ideas on why the furnace cement is cracking off? It's supposed to hold up to much, much higher temps, isn't it?

BTW, where can I find a pad like you described?

Try some JB weld instead. That stuff is pretty indestructable.

If it is the mastic used to seal ducts, then NO, The air temp in your ducts will never even get to 100

It's not the temps that are causing it to crack, but the expansion and contraction of the thin metal....in my humble opinion, of course Wink

The cement is cracking because of the expansion/contraction, and it was never designed to adhere to that surface.

You should be able to pick up a grill pad at Home Depot or Lowes, probably even Wally World, but they may be a seasonal item.
