In this video I repair another broken JCB TM headstock.
The middle plates, which have been ripped open, are removed. New stronger plates are cut out with the cnc plasma, a bevel edge is then cut for weld prep. They are then welded into position.
Once welding is complete, it’s time for the newly made line boring machine to be put to use! The bearings are aligned so the boring bar is parallel with the pivot pin. The line borer is mounted onto the bearing hub and the tool is set. 3 cuts were made to achieve final hole diameter.
Hope you enjoyed the video!
Thanks for watching.
