I finished up a welding task just today.  "wiring" a 42 inch snow blower auger.
The wire was 1/4" welded both in and out.  Five pounds of 6013. 
I'm not proud of the slag holes,  but the augers are beefy now where before they were torn and knife edged.
Took a bit of scrap tacked on to balance out the unit,  but It seems good now.    We will see when it's under power.  Single stage,  the auger turns at a good clip!
Tomorrow I've plans to fab up the shear bolt assembly based on the drive sprocket.  Mostly machine work, but there will be the AR400 plates holding the shear bolt welded to the sleeve that carries the chain sprocket.
Way too much time and effort into such a small unit,  But my wife said she would blow snow if the the blower didn't let her down ;-)
