I've always used a bandsaw mill, cut them as long as you can and 3 inches, any less and you lose the ability to cover all schools of longrifles...slab sawn is best to work with, quarter sawn you lose alot but can gain more figure but hey, it's either got it or it doesnt. Dont wait to saw it, seal the ends right away with good paint or wax. Sticker the boards at least one inch apart in the order it was sawn and apply sevin powder under and on each plank for at least 2 years, keeps the bugs away. Air dry at least 3 years or 5 is better...keep out of the sun and somewhere air moves some, not in the basement next to the coal or wood stove it will blow the wood apart, too fast. ...lol anything else let me know
