Yep, bin there dunnit. Once!Hi Jacob. As you know you can't just throw the sawdust on and smother the flames. If you do don't open the door to look inside. Woosh no eyebrows lol.
Solution is a big stove you can sawdust fill in one go and burn for an hour or so, then fill again when it's burnt right down and no danger of blow back. Can control speed of burning with the dampers
