A method for assembling a plurality of bucket assemblies having tangential entry dovetails onto a wheel of a turbomachine such that a predetermined circumferential force is obtainable on the bucket assemblies when assembled, includes reducing the distance between lateral faces on the base portion of at least a first bucket assembly and preferably all bucket assemblies, such as by cooling, and increasing the distance between the lateral faces after assembly, so that the predetermined circumferential force is obtained. Alternatively, the wheel circumference may be increased as by heating before the bucket assemblies are assembled. A combination of appropriate heating and cooling may be used. A closure piece having a predetermined circumferential expanse may be inserted in the bucket row of the wheel to obtain the desired circumferential force.
