I've got two felled oak trees dropped in thirty foot pieces that I need to buck or crosscut into 24 inch lengths for use in the fireplace. Now once the slices are 24 inches long I figure either the 6lb swampers axe or the 4lb splitting axe can go to work. So would you buck up the 30 footers with an axe, crosscut, or Bull Saw? If so what type? ( IE Single bit Jersey or Michigan, Tuttle Tooth Crosscut, 4T or 9T Bull Saw) Note my longest bladed chain saw is 18 inches and the cross section of the 30 footers is roughly 34 inches. Awaiting y'all's input, Thank You in advance.
