Laoich23 Posted December 30, 2010 Share Posted December 30, 2010 Going to forge a valve wheel. Like one you would see on a big pipe. About 12" diameter with one cross piece. Just curious if anyone has a method other than simply mig welding that cross piece in the ring. OR if anyone has ever seen older material on the task?

arftist Posted December 30, 2010 Share Posted December 30, 2010 They are usualy just grey cast iron. Nothing wrong with mig welding especialy for that purpose. Quote Link to comment Share on other sites More sharing options...

Timothy Miller Posted December 30, 2010 Share Posted December 30, 2010 The blacksmiths journal did a few pages on this forging. If I remember correctly he showed it as a bar with a square hole punched in the middle of it to receive the valve stem. The bar was fullered either side of the hole and drawn out to a rectangular section. These parts were split and spread apart. A ring was bent and forge welded from round stock. He shows the center cross as being either forge welded or brazed to the outside ring. He actually shows several way of doing it because I think he covered it more than once. I remember thinking why would you want to do that but it looked like a good way to expand ones skills. Quote Link to comment Share on other sites More sharing options...
