ABSTRACT:
An alignment tool for aligning the internal surfaces of multilateral tube sections to be joined. The alignment tool includes aligning members connected to toggle links which are in turn connected to a toggle actuator. The toggle actuator is effective to push a first area of bearing surfaces on the aligning members into contact with internal surfaces of the first tube section. The toggle actuator is locked into position in the first tube section. Internal surfaces of a second tube section are slid over exposed second areas of the bearing surfaces of the aligning members thereby aligning the first and second tube sections. The tube sections are connected; the aligning members are moved away from the internal surfaces and the alignment tool is removed.
