An apparatus for forming heat exchanger core assemblies having a plurality of generally elongate tubes seated in uniformly spaced openings in a pair of spaced parallel header members is disclosed. The apparatus includes a generally flat, horizontal support table and a pair of header carriers mounted for horizontal reciprocatory movement respectively toward and away from two opposed sides of the table. The apparatus further includes a pair of elongate, horizontally disposed guide members for locating and aligning a plurality of tubes with the respective openings in header members. Each of the guide members includes a base portion and a plurality of finger members, each finger member projecting in a first position vertically upwardly from the base portion. The guide member further includes a plurality of upwardly opening elongate, tube receiving slots between the finger members, the slots extending parallel to the adjacent side of the table. The guide members are formed from an elastomeric material, such as a polyurethane, so that each of the finger members can be deformed elastically under imposition of a lateral force thereagainst and return to an original position when the force is removed.
