1. A method for prealigning and clamping a series of tubes in parallel alignment comprising the steps of:
- providing two elongated parallel bar halves, having a series of spaced alignment protrusions extending from at least one of said bar halves toward the other of said bar halves and having opposing alignment openings through the other of said bar halves for respectively receiving said protrusions therethrough in alignment when said bar halves are clamped toward each other, positioning said bar halves in parallel with each other with a series of nonaligned psuedoparallel tubes respectively positioned in prealignment between said protrusions and perpendicular to said bar halves, and thereafter drawing said bar halves together in guided clamping engagement to retain said tubes in parallel alignment.

Abstract
A self aligning tube alignment bar for aligning and retaining a vertical series of boiler tubes in parallel. The tube alignment bar is comprised of two elongated parallel bar halves having a series of opposed recesses with interengaging protrusions therebetween to initially loosely confine the series of tubes respectively in a separated series. Thereafter the two halves are drawn together by bolts causing the two alignment bar halves to have their protrusions interengage and thereby guide the two halves together in clamping engagement such that ultimately the tubes are retained in a parallel series.
