I am going camping next weekend and think it would be cool to start a campfire using a fire bow drill. I have all the parts, but can only seem to get just a bit of smoke at best. I'm not sure what I'm doing wrong. I put pine tar on the string to keep it from slipping.The wood for the fire board is cedar, and the spindle is made of poplar.I watch Survivorman on the Science Channel, and he makes it look so easy, but it is not easy!
