A bucket of stuff from an auction buy included a clevis but no bolt.
Found an odd ball bolt from another bucket that was just slightly larger than what I needed for the pin.
Easy enough to turn the bolt down and thread it on the lathe. Then I decided that I wanted two flats milled on the "head".
Hmmm, no good way to hold it in the mill vise. Dug through yet another bucket and found a piece of scrap steel that I could make into a V block.
Some time in the shaper and then in the mill and it was good enough for simple loose tolerance jobs. Good practice for both machines.
If I had more money than time it probably would have been more efficient to just buy a new clevis, but what's the fun in that?
