I'm building a bed and am new to wood work. I thought since I could work on cars I could design and build my own bed, harder than it seems.
I'm trying to attach 4-2x12's together to form a square, the boards are overlapping at each corner for attachment. I use wood screws and tried to connect it from the outside of the board but its not a stable connection and boards keep coming apart.
Do I need to drill holes and use bolts/or screws?
Use L-shaped brackets at the corners?
