Considering the strength of specimens, of timber it was found that the drying of hot air from Table 2 according to the conditions of hot air temperature. Affect the relationship of strength, it was found that the temperature value of 50 C tension strength parallel to grain compression strength, perpendicular. To grain shear strength, parallel, to grain static bending and hardness was 0.2282 0.4108 0.4464,,,, and 1.9584 114.5457 43.1 respectively. If the temperature increases the round increase. The strength of the board will decrease the most 100 C was tension strength parallel, to grain compression strength perpendicular. To grain shear strength, parallel to grain static bending, and hardness everybody, less than the round you ear Mi low.
