Watch this 33-minute tutorial on welding and line boring a rear frame articulation joint for a Franna crane restoration project. Follow along as the Cutting Edge Engineering Australia team tackles the complete process of preparing the new articulation plate, starting with extensive welding work. Learn how they clear stubborn components from the rear frame, including rusted trailing arms, old brackets, and spherical bearings from steering cylinders. Observe the precise setup and operation of a Sir Meccanica WS1 portable line borer using centering cones for perfect alignment. See how they address porosity issues by boring out the top hole, laying fresh weld, and then line boring both positions to exact specifications. This comprehensive workshop demonstration showcases multiple engineering skills including welding, fabrication, and precision line boring techniques all applied to a real-world heavy equipment restoration project.
