Often in the manufacture or repair of furniture made of particleboard require dowels of circular cross section. Manually with a knife to whittle them long, and the diameter of turns of equal length. I propose to make dowels from wooden slats, for example, a cross section of 9×9 mm punch cuts a hammer through a hole with a diameter of 9 mm in a metal plate of thickness not less than 10 mm. Preferred material for dowels pine slats. A. SHEVTSOV, Kaguya
