A method of joining two ferrous alloy component parts. The method includes hot metal casting a portion of a first ferrous alloy component part onto a first joining surface of a low carbon intermediate element; friction fitting a joining surface of a second ferrous alloy component part against a second joining surface of the low carbon intermediate element; and fusion welding with a concentrated energy source the intermediate element to the second ferrous alloy component part. The hot metal casting includes flowing a molten ferrous alloy onto the textured first joining surface, wherein the molten ally encompasses tabs extending from the first joining surface and filling apertures defined in the intermediate element. Then cooling the molten ferrous alloy such that a metallurgical and mechanical bond is formed between the portion of the first ferrous alloy component part and the first joining surface of the low carbon intermediate element.

Provided is a method of molding an elevator and an endoscope, the method making it possible to mold an elevator integrally with an operation wire with a simple operation. A method of molding an elevator (36) is a method of molding an elevator (32) integrally with an operation wire (40), the elevator (32) being to be disposed in a distal-end-portion body (32) of an endoscope (10). The method includes: a step of disposing the operation wire (40) to extend through a cavity (106), which is formed by a first die (102) and a second die (104) that are separable in a separation direction, in a state in which the first die (102) and the second die (104) are mated to each other and in which the separation direction and a wire-axis direction of the operation wire (40) coincide with each other; a step of integrally molding the elevator (36) and the operation wire (40) by injecting a molding material (108), which is a material of the elevator (36), into the cavity (106); and a step of separating the first die (102) and the second die (104) in the separation direction after molding the elevator.

Disclosed is a handle clamp for an exothermic mold. The clamp includes a pair of legs, each having a plurality of rods that are shaped to fit into engagement holes on sections of the mold. The rods of each leg engage with one section of the mold. Engagement brackets are rotatably disposed on one or more or the rods. The brackets each have a thumb bolt that can be extended toward a mold section connected with the clamp. When engaged with the mold section, the thumb bolt stabilizes the mold section on the handle. A detent mechanism is provided between the bracket and the leg of the handle. The detent mechanism releasably holds the bracket in one of a selected plurality of rotational positions with respect to the rod. By selecting different rotational positions for the brackets, the handle can be configured to engage with different configurations of mold. The thumb bolts that are biased toward the mold section by a spring. The bolts include a key that can be aligned or misaligned with a key slot on the bracket. By aligning the key with the key with the key slot, the bolt can be moved toward or away from the mold section under the biasing force of the spring. By misaligning the key and key slot, the bolt can be locked into engagement with the mold section or else held in a disengaged position.
