Not really a grate idear if you have powerfull engines with lots of torque changes. I hope this one is for something unimportand. 1. Crankshaft are forged wich means they lose stability if heattreated with a torchflame 2. Crankshaft are balanced on rotation wich is necesary to not brake at 3000 - 5000 rpm. Welding it together will unbalance it. 3. every Crank on the shaft has a precise location. if it out of place the engine piston will not be at the right position when the fuel is ignited wich can cause futher damage to the engine. And will make it run dirty. But I am sure they just cant get or afford a new one, so it is the only way to go.

[@oh8wingman]

Before everyone gets the idea that they can do this with what came out of their old Chevy or Dodge, you best consider this: This crank is NOT cast iron. It is in reality forged steel. That little gob of weld on the end of the first piece is their way of checking to see what material it is. If it doesn't take a weld like that they junk it. Once the material is established you can see how it machines. Cast iron does not machine large chips as shown but more like a sand or powder. Forged steel will leave large chips like those shown. Another telltale is at <a href="#" class="seekto" data-time="694">11:34</a> with the other end of the crank. You can see how the throw has been cut down with a cutting torch to save on machining. Cast iron will not cut very well if at all with a torch. Also, if you look carefully, from time to time you can see the marks left from where the forging dies join together. You can repair a forged steel crank this way and if you are careful to get the two pieces back into alignment there is no reason why it won't work. I have seen large cranks used in industrial engines that were fabricated from smaller components and welded together much the same way as this.

[@wendelllovatti]

hahah i agree. i see the electrode 7018 or 6010 hard steel he was welding so it is not cast iron.

[@nzsaltflatsracer8054]
