The parts thus assembled areplaced in the furnace and heated sufficiently to be welded to-gether with one operation under the steam hammer. The die parts are held in position by keys through the cross-bolts, which facilitates the assembling and dismantling for weld-.

When the parts assembled are sufficiently heatedin the furnace, they are placed in position in the die and thewelding is completed by several strokes of the plunger. Afterthe transom end leaves the die, the forming has been so well ac-complished as to render unnecessary any further dressing ortrimming. After the ends have been formed they are welded tothe crossarm in the regular manner on the transom. SPRING MAKING AND REPAIRING. G. M.
