It's like a Swedish Candle.
Ive seen things like this being sold in stores, where its an asterisks shape cut out of center (just punching a chain saw straight down to make a few pie slices but still leaving the edges in tact)
Whoa whoa whoa...its a cut up stump with a bit of tinder in it lolI see them at Walmart and Home Depot. There are folks paying $15-20 each for a cut up stump.
It's a Swiss Candle. You can make these with a chainsaw cutting down the length of a log, but leaving the base intact. It's the air flow through the cuts that make it work. A closed sided log could work if it's bored through and air can enter the base.Ive seen things like this being sold in stores, where its an asterisks shape cut out of center (just punching a chain saw straight down to make a few pie slices but still leaving the edges in tact)
