Not on the ones that I'm planning on clearing. They're just stragglers really that have grown in the shade of the larger oaks. I might be lucky and get the odd post , but they'll mainly be firewood.
I do mill the odd few planks with a chainsaw , I just do it freehand.
I bought a cheap alaskan mill , and chainsaw with a 24" bar. It's OK for soft wood , but the oak was just too much for it.
