I want to make the world's longest griddle so we can cook a dozen Jiffy Pops at the same time, as a race. Criteria: cheap, safe, single-use. The heat source could be BBQ charcoal, but maybe simpler/faster to start & stop would be a dozen cans of Sterno canned heat. The JiffyPop aluminum pan sometimes melts over open flames, so instead of a wire mesh I'm thinking a metal griddle would be best. But a proper cast iron griddle would be too expensive. A long sheet of aluminum siding would probably melt through. How about a long section of galvanized steel ductwork, the type used in home heating? Would exposing that to direct flame be a problem? Any other suggestions? Note the food itself won't touch the griddle; I'm not frying eggs. I just need a flat surface that will take the heat for an hour, ideally something I can buy cheaply off the shelf. Thanks!

I have a problem with a barbecue that is driving me insane, and need some help, please. This unit is two years old. It has five straight burners inside and one circular burner at the side, and an igniter button operating all six igniter wires. The propane is fed via a tube that is routed to a point underneath the side burner where the side burner tube taps in, then runs along the front of the barbecue feeding all five inside straight burners. The first time I used it this year, it lit up normally. The second time it refused to light! I thought the tank might have been empty, so I replaced it with a full tank. Still does not light. All igniter wires look fine and the burners are not excessively corroded to prevent sparks from jumping the gap. The old tank I think still has some gas, but am now testing with the full tank. I have reset the regulator by turning off the gas at the tank valve, disconnecting the regulator and letting it sit for a while before reconnecting. Still it does not light! Then I removed a connection of the tubing underneath the side burner and pushed a wire all the way down the tube. Could not feel or pull out any debris from either side, so I replaced the connection. Still it does not light! Tried using a long tube butane lighter to see if I could light it that way. The side burner lights and burns with a decent flame on high. I was able to light the straight burner closest to the side burner after a while of waiting for gas to build. But that's it. None of the other burners want to light. Seems that not enough gas is getting to them maybe! Do I need to replace the regulator or is something else going on here? Thanks, quickcurrent
