I’m new to using a side blast forge. I recently bought this a month ago just now trying to get it started. I have sand at the bottom about 4 inches. On top I filled with coke. When trying to start a fire I make a hole 3 inches away from air flow. I use my gas forge to heat up the coke and put it inside the hole and slowly add air. I have no luck. I’ve tried kindling wood and cardboard. I’m used to using a forge with a pot and air from the bottom. Any help would be appreciated.
