Final answer:
In woodworking, the correct depth for a dado (a groove cut into wood) is usually determined based on the thickness of the stock. There's not a universal answer, but it used to be 5 widths side-to-side and 7-8 deep, and now it could be up to 8 diameters side-to-side and 15 diameters deep.
Step-by-step explanation:
In woodworking, a dado is a groove cut into one piece of wood, into which another piece of wood fits snugly. The correct depth for a dado is usually determined based on the thickness of the stock (the material from which you're cutting the dado).
An older 'rule of thumb' suggested a depth of 5 widths side-to-side and 7-8 depths deep. However, more modern interpretations suggest anywhere up to 8 diameters side-to-side and 15 diameters deep, depending on the specific project and the strength needed.
Bear in mind that a too-shallow dado might not provide enough support, while a too-deep dado could weaken the stock. It's often best to start conservatively and then adjust based on results.
