Metallurgy for Dummies/Carl/John
Some concerns about my use of mild steel for my swingarm have been raised. There are terms that always bring a knowing smile and a nod of the head to most people. Terms like "Board Certified", "Micro Brewed", "Heliarc" and "Chromemoly". While I have no problem with the last two, I believe them to be, at times, buzz words. I'm a lousy TIG welder, so that's out the window on this build. Cars, bikes, high rise office towers and a myriad of other stuff has been built out of mild steel, with success for a hundred years. They have been gas, arc, MIGed TIGed, bolted, rivited, furnace brazed and even glued together. I believe my swingarm will be just fine. I don't know what BH uses, but the induced hydrogen embrittlement from the chrome plating would certainly negate some of the advantages of using chromemoly. I'm gonna run it and like it. If it fails, I doubt that it will be catastrophic. I will be keeping a close eye on all of the modifications for signs of failure. Just ride in front of me so the parts falling off don't hit ya.
