How to make a solid wood table without nails?

Mortise and tenon (s ǔ n m m m m m m ǐ o) is the main structural mode of ancient buildings, furniture and other appliances in China, and it is the connection mode in which concave and convex parts are combined on two components. The protruding part is called tenon (or tenon); The concave part is called mortise (or mortise).

Technical requirements of traditional mortise and tenon structure: the thickness of tenon is less than the width of mortise (0.1-0.2 mm); When the thickness of tenon is greater than the width of mortise, the glue will be lost by extrusion, which will reduce the bonding strength and the mortise will easily crack during assembly. The tenon width is 0.5- 1mm larger than the mortise length, and the hard material is 0.5mm and the soft material is 1mm.. The length of tenon is 2-3mm smaller than the depth of mortise and more than half the thickness of mortise. Right-angle tenon thickness: the single tenon is close to 0.4-0.5 of the previous thickness, and the total thickness of double tenons should also be close to this value. The ends of tenons are usually chamfered to facilitate insertion into mortises. If the cross section of the part exceeds 40mm×40mm, double tenons should be used. The tenon joint adopts bottom hole, and the thickness of tenon should be adjusted to the same size as the square drill. Commonly used thicknesses are 6mm, 8mm, 9.5mm, 12mm, 13mm, 15mm, etc.
