I picked a nice large stump which is tall and thick and unreasonably hard to move. Pick a stump which is relatively flat on both sides.
One side was great, the other side only had 6 or 7 centimeters to grind off. Dry the stump This takes a long time (months) and you have to protect it from the rain, bugs
mold, fungus, termites.
