We tried a lot of non grill ignitor or flint methods. As in NZ I can't find either of those. I found an ignition coil in the garage and though 'Why not?' But the sparks sucked. I hooked a camera flash to pump the coil and CRACK! massive thick spark. If you look through the pictures you will see how easy this actually was.
