A method of making bifurcated tube bends for power boilers, comprising the steps of: providing a straight bifurcated tube (2) mounting a bottom former (4) on a bending machine through a stay bolt (11) having a bottom profile of the bifurcated bend to be produced from said straight tube (2) placing a top former (5) having a top profile of the bifurcated bend over the bottom former (4) providing a drive Pin (6) to avoid eccentricity between the top former (5) and the bottom former (4) disposing a top plate (7) to hold the stay bolt (11) and the top former (5) together locking the top former in the stay bolt by using a nut (8) interposing a hexagonal socket head screw (9) to hold the top former (5) and the top plate (7) together locking the drive pin (6) in its position by applying a grub screw (10) and importing a simultaneous motion of the former assembly (4,5) to produce a required bend radius of 76.2 mm in the reheater tube (2) initially having an outside diameter 63.5 mm.
