One manual method to find a stud is to look for nails in the baseboard.
Here's how this method works based on the provided reference:
- Carpenters often nail the baseboard into the studs using 2 1/2 inch, 16 gauge nails. Therefore, these nails indicate the presence of a stud.
- Visually inspect the baseboard for nail holes or filled nail holes. These are usually evenly spaced and can give you a good indication of stud location.
- You can also use a strong magnet to find the nails holding the baseboard to the studs.
While other manual methods exist (like tapping or using a strong magnet on the wall surface), the baseboard method offers a relatively reliable starting point.
