I can remember as a very young kid seeing a kids map of the world and animals and people in the upper northern hemisphere was standing up straight and the penguins in the antarctic and the stuff in the lower southern hemisphere was shown upside down and I remember wondering why that southern stuff didn't fall off the earth

Something like this with animals and people

Once in my physics 1 class, the professor called on me and asked for an answer I totally didn't know. I replied "Who cares, the earth is flat and this is all made up BS anyways." I don't think he knew if I was being serious or not, so he just called on someone else.

One for @timg and any other metallurgical experts.
Pins worn, bushes not so by eyecrometer at least. Auto greaser working.
I really enjoy my job on days like this where I get to help with something interesting.

No expert here Adam, but thanks for the comment.
I would tend to think the pin missed it's nitriding process. Was that pin customer built? Nitriding is better than carburizing as you don't want through hardness just surface hardness. Carburized pins will completely fracture in halve. My only suggestion is to add some grease ways into the bronze bushings out from the center. You would need a football burr for non ferrous metal prolly same as what guys on here port saws with. Be sure they add the dirt seals that are missing in the boom front. It will help keep out the abrasives, red zealie dirtzzz.
Morning to the rest of yinzers. Woke up to 4" of snow and still coming down. Have a great Sunday guys. Peace out.
