My brother asked me back in September if I coud build a rail for his front steps since the old wooden one was rotting out. I'm self taught, been welding about a year and a half on weekends, so I told him I'd do it for the cost of steel and a case of beer. He sketched out what he wanted, mostly simple uprights with a curved top rail, nothing too wild.
Biggest thing I learned was to tack everythign in place first and check it against the steps before fully welding. I rushed one section early on and the whole panel came out twisted, had to cut it apart and redo it. That cost me two evenings right there. Once I slowed down and squared everything up with clamps it started going togather way cleaner.
Used square tubing for the frame and painted it with a rust inhibiting enamel since it's an outdoor rail and I don't want him calling me next spring about orange streaks. He's happy with it and his neighbor alredy asked if I'd take a look at thier steps. Might have accidentally started a side business.
