In this video i repair a Protech post knocker.
The tube that holds the bushes for the main pivots had stretched causing excessive movement.
I cut out the old top pivot tube with the arc air gouger, machined up a new one on the lathe out of a bit of 75mm round bar and welded it on.
I noticed the bottom pivot was starting to do the same so i cut the outer bushes off and machined some new ones for there as well.
Last job was to repair the stop for the stone spike.
Hope you enjoy the video.
Thanks for watching.
