Chapter 3 Traditional Processing and Its Products 31 ;:a; . .. _ 1 __ _:...c-_-=-====:=== Figure 3.44 Half-wall Infixing Tenon Figure 3.45 Sketch Map of Half-wall Infixing Tenon c. Fish mouth Fish mouths, set up between two horizontal framework culms to support the whole, are often seen in tenoning. Liner heads, functioning as fish mouth, must save the nodes and partitions. Make the head V-form by using the handsaw without damaging the partitions. Cut and pare into an arc concave, like a mouth fish, and make the head stick tightly to the arc of framework culm Figure 3.46 Fish Mouth (Figure 3. 46). Generally, the fish mouth upwardly holds the framework culm. d. Level infixing tenon Level infixing tenon needs no processing of liner heads. Liner heads can be level on one end or two. If only on one end, the other end is fish mouth. Make two holes on the infixing position on the framework culm by using a hand drill, then cut and pare them to the holes whose diameter equals the liner head's diameter. The assembling of level infixing tenon heads: to infix one end and then pull the other culm away to make the other level head infixed into the tenon mouth. If it is a single level, insert one end and pull the other end to the proper position along the last culm's direction. Make the upward fish mouth lean tightly against the culm wall and the bottom into the tenon, tightly against the inner wall as well.

Be aware that nails must penetrate the wall and partitions on mouth level end, and nails on level head must penetrate the culm and wall of liner head as well to make them intensified (Figure 3. 47 ) . Level liner, widely used in producing bamboo furniture, is installed between framework culms, horizontally or vertically. Be aware that the level liner cannot be over-thick or the mechanic functions may be affected. e. Bevel infixing tenon Bevel infixing tenon has bevel tenon at the liner head (Figure 3. 48 ). The liner also is called as bevel liner. Bevel infixing tenon cannot be wholly infixed into the hole. It is not suitable for first-class furniture due to its less tight combination. Generally, bent liner cannot be directly tenoned vertically with culms and bevel infixing tenon is thus applied. Bevel infixing tenon can be single or double headed. Be aware that the inclined interface must face the same direction as the fish mouth on the other end does if it is a single bevel tenon (Figure 3. 49). Intensity will be affected otherwise. -. ,. -•.... - Figure 3.48 Bevel Infixing Tenon Figure 3.49 Sketch Map of Bevel Infixing Tenon f Dovetail infixing tenon Tenon heads at the liner end face the inclined interface, which look like a dovetail. This liner is also called as a dovetail liner. Dovetail infixing tenons (Figure 3. 50) have two drilling holes as tenon holes. The space between the two holes must be equal to the space between the dovetails. Dovetail tenon is always single headed and the other end is generally fish mouth. Bamboo nails are fastened at the fish mouth (Figure 3. 51 ) . Dovetail infixing tenon is seldom applied in frrst-class furniture for its less intensity and integrity. It can be horizontally or vertically assembled between culms, among which more vertical assembling can be found. The relationship between dovetail infixing tenon and fish mouth is the same as that between bevel infixing ten-
