I have had a Hasty Bake for about 5 years now (its at least ten years old). I have fiddled with it, fooled with it, messed with it, and I just can't get it to stop burning the hell out of coal. Its just too drafty, top and bottom. I still love it, it does a darn good job. The best part is the ability you get when you grill. You can crank the fire box up to withing three or four inches of the grate and get a perfect sear on a piece of meat, then crank it down to finish it off if need be. But if I could get a slow, properly drafted fire out of it-wow. I am thinking of sealing doors with gasket and maybe adding a stack. Anybody Buelller, anyone?
