<human>: Objective: How to cut a new center plank for your picnic table?

Which of the following solutions is more sound in terms of naive physics reasoning?

OPTIONS:
- With the trough dimension measured on the center plank we can chop off the ends. Using a chisel the ends were cleanly cut from the center plank. The ends pieces were then reattached to the table on the new end cleats.
- With the trough dimension measured on the center plank we can chop off the ends. Using a saw the ends were cleanly cut from the center plank. The ends pieces were then reattached to the table on the new end cleats.
