Whoever had my mill before me decided that the way to remove the pin that the knuckle pivots on was with a hammer. As such the threads were mashed beyond repair. I thought that I had a picture of when I removed it, as I had been photographing damaged items to assist me when I ordered new parts. I guess I didn't bother as I new I would do the fix myself. The original thread was a smaller diameter then the actual pin and I'm guessing it was M24.
I rummaged through my stock and the biggest nut that I could find was a castle nut with a metric 1.50 pitch. I measured the minor diameter of the nut and then used a programme I downloaded from the net to figure out what thread I needed to cut to match the nut.
It turned out that it was a M22x1.5, so I turned the end to be threaded down to 21.85mm, which was a fraction smaller than the relief grove on the original thread, and cut the thread.
I'm very happy with the result and the fit is nice a tight. I'm either going to turn off the projections from the castle nut or make a new one (that would be further down the track though). The nut really is there for aesthetics, as there is no way the pin would just slip out. So I'm thinking of a large diameter washer (same size as the other end of the pin) and a cleaned up nut will work fine for me.
