The length of the nail chosen should be 2.5 to 3 times the thickness of the work being nailed. To increase the firmness of the connection, there should be an angle when nailing, forming a dovetail oblique nail combination to produce a hook effect.

When the wood is nailed, the long end should be sawed first to reduce the splitting of the wood.

When nailing the hardwood nails, the nail holes should be drilled first, and the hole diameter should be slightly smaller than the nail diameter.

At least two standard nails should be driven into each connection surface to ensure the connection is firm.
