I might do that once, for fun. However, my friend and I had 2,100 bd ft of
white oak milled last spring, and are about to have the same amount of black
oak and walnut milled when the weather warms up -- already at mill waiting.
We did a couple thousand bd ft of walnut and white oak a few years back.
Some of the logs weighed around 3,500 lbs.
Can you imagine riving all that?
My mother lives in a forest. Most of it (40 acres) is under a conservation
easement, and we cannot even remove deadfall. The remaining 15 acres is
preserved by us because we want to preserve it, but storm-topped trees or
those that are dying near buildings are harvested. Most harvested trees are
around 100 ft high -- as much as 130 ft for the oaks. They are first-growth
trees. Last August, it actually took the winch on a tow truck to pull four
black oak logs out of the woods (we minimize footprint and damage). The
butt logs were about 32 - 34 inches inside the bark at their bases and
tapered very slowly. On our sawyer's big Woodmizer with its narrow kerf,
logs that size yield maybe 500 bd ft each.
