There's not a lot of great power-hammer related discourse here, of late... you might try over in the Power Hammers subforum at IforgeIron.com. There's some Fairbanks owners there. Also, I believe Ken Zitur of kensiron.com, maker of KZ hammers, runs a #150 Fairbanks. He's got a vid or two featuring that hammer, on Youtube. You might reach out to him. Will Stelter of Stelter Edgeworks, a student of mine, also has a 150 Fairbanks... he's on Insta and FB if you have a look around, and would likely be happy to talk hammers with you.
