Alaska Posted May 20, 2009 Share Posted May 20, 2009 need some help this has not been happening but it started last week and I can not see why I have not Changed anything help why is this Quote Link to comment Share on other sites More sharing options...
Dave Budd Posted May 20, 2009 Share Posted May 20, 2009 details please are you getting warping when heating, cooling, quenching, tempering, etc? are you normalising the steel after forging? Are you working unevenly on the steel (working solely on one side of teh balde will cause warping)? give us info! :D Quote Link to comment Share on other sites More sharing options...
Steve Sells Posted May 20, 2009 Share Posted May 20, 2009 maybe because it happened when ya did that thing? The are many reasons for warping, from built up stress in the metal to bumping it while heating in the coals. Give us complete information, and you can get more accurate information about what is going on. Quote Link to comment Share on other sites More sharing options...
Alaska Posted May 21, 2009 Author Share Posted May 21, 2009 it is when I am quenching and yes I am normalising thinking about it I have been just a bit stressed it may have something to do with it just may not be getting something but should have soon time to work on it Quote Link to comment Share on other sites More sharing options...
Rich Hale Posted May 21, 2009 Share Posted May 21, 2009 Lots of folks here that can help ya maybe but you got to give up details,,wot kind of steel? are you grinding or forgeing,,wot do you quench in and do you heat it not able to help uless you tell us more...Fill in the details Quote Link to comment Share on other sites More sharing options...
Steve Sells Posted May 21, 2009 Share Posted May 21, 2009 (edited) it is when I am quenching and yes I am normalising thinking about it I have been just a bit stressed it may have something to do with it just may not be getting something but should have soon time to work on it not YOUR stress. internal metal stress Edited May 21, 2009 by steve sells Quote Link to comment Share on other sites More sharing options...
Dave Budd Posted May 21, 2009 Share Posted May 21, 2009 no YOUR stress. internal metal stress same thing isn't it? I know when I'm stressed more things go wrong :rolleyes: Quote Link to comment Share on other sites More sharing options...
Alaska Posted May 22, 2009 Author Share Posted May 22, 2009 I am forging with coal and charcoal and some times wood but that day it was charcoal rail road spike I quench most the time in water for a rail road spike to get them hard and it is my stress and may have forgot something I do not think I did but ? going to be working with a lot more 5160 just got 500# of it and will go back to oil quenching then it was a hot day and I do not forge a lot on hot days Quote Link to comment Share on other sites More sharing options...
Frosty Posted May 22, 2009 Share Posted May 22, 2009 A RR spike doesn't have enough carbon to make it hardenable anyway. Even superquench will only make it less than prybar springy. Frosty Quote Link to comment Share on other sites More sharing options...
Alaska Posted May 22, 2009 Author Share Posted May 22, 2009 OK that was it Quote Link to comment Share on other sites More sharing options...
Frosty Posted May 22, 2009 Share Posted May 22, 2009 I still don't know enough about how you treated it to guess why it warped, there are a lot of possibilities. Just because it's mild steel doesn't mean it won't warp under many different conditions. Heck, the cause may have happened before you got it. Regardless, being mild you can straighten it without annealing, normalizing, etc. maybe even cold. If it's twisted you can try putting it in a vise and use a wrench. If it's bowed try a wood mallet on a wood block with a hollow. This works very well hot too. Wood won't damage detail or change cross section so your finish forged details won't be damaged if it has some mass to it. Things like horns, thorns, leaves, etc. will of course be bent and maybe damaged even by wood on wood. Frosty Quote Link to comment Share on other sites More sharing options...
Alaska Posted May 24, 2009 Author Share Posted May 24, 2009 thanks will try when I get some time have a lot of work on the land will be forging when I get time I hope a lot more then it looks like Quote Link to comment Share on other sites More sharing options...
Messerist Posted June 6, 2009 Share Posted June 6, 2009 Has anyone here heard of the practice that when you quench a blade edge down you should have the blade oriented to magnetic north? I have read that it keeps thinner blades from warping. Quote Link to comment Share on other sites More sharing options...
Charlotte Posted June 6, 2009 Share Posted June 6, 2009 Messerist, I think that quenching to the magnetic noth is an idea from the same people that send you after angle streachers and board strechers. Seriously, warping comes for stress that are residual in the blade and/or quenching so that one side cools faster than the other. Quote Link to comment Share on other sites More sharing options...
Alaska Posted June 7, 2009 Author Share Posted June 7, 2009 thanks for all the great help here. when we start getting rain again so I can forge just to dry here right now I will try some of the things Quote Link to comment Share on other sites More sharing options...
Frosty Posted June 8, 2009 Share Posted June 8, 2009 The old story is about normalizing by laying hot iron/steel in the dirt aligned magnetic north. It's supposed to make it tougher. Frosty Quote Link to comment Share on other sites More sharing options...
