I bought this wrench for $5 and tried my best cleaning it, but since I couldn't take it apart due to the pin being peened in place, it wasn't quite good enough. It ran all kinds of rough and required two hands to use. So I drilled out the peening, really cleaned what I couldn't previously reach, and ran it through a tumbler to make it nice and smooth. Then I drilled and tapped a 5/16 - 18 hole for a set screw to keep the pin captive. Now it runs like a dream, and I can take it back apart with a hex key.
I wanted to do the set screw in brass, but didn't have any 5/16 brass bar stock kicking around. Maybe next time.
