The dewel joint is one of the most widely used joint types in modern woodworking, especially in wooden furniture manufacturing. L-type specimens of two solid woods(Antiaris, Sepetir) and three wood based materials (Plywood, Particleboard, and Medium Density Fiberboard), 15mm thick, 100mm wide, and 150mm long in size, were constructed with 1, 2, 3 and 4 dowels of 6, 8, and 10mm diameter by polyvinyl acetate resin adhesive in this study. Stiffness coefficient and strength of the L-type specimens were determined by the aid of universal testing machine. The stiffness coefficients of the specimens constructed with one dowel was in the 10^-3 level, indicative of flexible joints but those with 2, 3, 4 dowels were in the 10^-4 level, indicative of relatively stable joint. The 8mm dowel was superior to 6 and 10mm dowels in bending strength, and the bending strength increased with the increase of dowel number from 1 to 4, however, the increasing rate of bending strength from 1 to 2 dowels was higher than from 3 to 4 dowels. The most superior joints strength was obtained in constructions with 4 dowels of 8mm diameter for wood based materials (Plywood, particleboard and Medium Density Fiberboard) and with 4 dowels of 10mm diameter for solid wood(Antiaris and Sepetir), respectively.
