The present fabrication apparatus includes pivotable die blocks and a stationary half-moon male die for bending re-rods. Front inner portions of the pivotable die blocks bring over-center pressure on a bent rod so as to control the tendency of a bent rod to spread after removal from the die blocks. The pivotable die blocks are mounted in a housing with a threaded pin connector for drawing the pivotable die blocks toward and away from each other to adjust the housing to bend rods to a variety of radii. The housing further includes upper and lower plates sandwiching each of the pivotable die blocks. Parallel ridges are formed in confronting surfaces of the upper plate and a transverse bar to increase the capability of the transverse bar to prevent the housing from being spread apart as a rod is being bent.
