Zusammenfassung:	An apparatus or cradle having top and bottom supports is used to assemble, transport, and deploy a bottom hole assembly. The cradle supports at least a whipstock and mill of the assembly during assembly and transport. At the rig, the assembly and at least the mill support are lifted, and a portion of the assembly is through a rotary table of the rig. The assembly is then supported on the rig by engaging a base of the cradle on the rotary table. A milling tool is connected to the mill of the assembly, and the assembly is disconnected from the at least one support of the cradle. The assembly and the milling tool can then be run through the rotary table for deployment downhole.
