I have a question for some of the wood experts here. I just purchased a Woodstock Fireview this year and they recommend 16". Firebox is 19". I just got a bunch of free red oak and chestnut oak today and this is next years wood. It was cut between 17" to 21" in length. Most of the rounds I got are about 20" in diameter. Should I cut the rounds before I split with the chain saw and used the small pieces as chunks, or should I split it and use my miter saw to cut it after they are split? More cutting but easier. Thanks Jeff
