Ben_C Posted July 13, 2007 Share Posted July 13, 2007 I've Noticed recently that cracks have been forming in the radius area of shoulders I've formed using either the anvil edge or a spring fuller. The cracks are small and form a sort of spider web pattern. These cracks also seem to seriously degrade the metal as they break easily at this point. I'm not sure what is causing this I never burn this area and am at a loss of what to do to prevent this. Any thoughts? Quote Link to comment Share on other sites More sharing options...

Ben_C Posted July 13, 2007 Author Share Posted July 13, 2007 I'm sorry I should have included that! I'm just using hot rolled mild steel. Quote Link to comment Share on other sites More sharing options...
Tyler Murch Posted July 13, 2007 Share Posted July 13, 2007 That shouldn't happen normally. Is it A-36? Every now and then, that stuff can be pretty junky. Quote Link to comment Share on other sites More sharing options...

Glenn Posted July 13, 2007 Share Posted July 13, 2007 You bending hot metal or cold metal? What diameter? What Radius? Quote Link to comment Share on other sites More sharing options...
johnny99 Posted July 13, 2007 Share Posted July 13, 2007 1. Working the metal to cold. 2. poor technique, folding wrinkles into the radius instead of stretching the metal outward. 3. bad batch of metal. Quote Link to comment Share on other sites More sharing options...
Chris Pook Posted July 13, 2007 Share Posted July 13, 2007 My guess is working it to cold and not keeping the smaller shoulder'd piece square to the anvil/fuller when its getting cooler. Quote Link to comment Share on other sites More sharing options...
