Thank you Sven. Your photos look quite similar to the Live Oaks around here, although with smaller pores.
I’ve been scared off of my interest in working Live Oak for the time being based on a piece of Pecan (Hickory) I picked up yesterday. Live oak is almost 50% harder than pecan and I’ve had all I care to handle for now.
I spent two hours flattening one side of an 17”x28” (43cm x 71cm) slab. It will make a lovely small bench, but I could hardly work from one side to the other without sharpening up at some points.
