FIELD: construction.
SUBSTANCE: three workpieces in the form of a rhombus in a longitudinal section are connected together by vertexes with corners 120° with formation of a hexagon prism, preliminary having put glue on adjoining surfaces, are placed in a restrictive contour, are dried and machined with manufacturing of the bush with demanded sizes. The rhombus party is accepted from a condition z=h/cos30°=h/0.866, where h - strip height equal to the sum of exterior radius of the bush and a diametrical upper allowance on a tightness, shrinkage and a final treatment.
EFFECT: invention solves a problem of decrease in power inputs and labour input reduction at manufacturing of bushes from the pressed lumber.
