    That is good to know, I never considered silvering it.........

      That's right.

      The goal is ductile.

      The blade isn't under a huge amount of tension, but boy does it flex many many times.

      80% of failures are from 20% of causes
      Never compromise your principles today in the name of furthering them in the future.

        Call me crazy but I have used one of these: On repair of blade we would cut off previously heated metal.

          Thanks

          I took fatfabs advise and it worked fine. One blade was brand new and was to coarse to cut thin angle iron and broke right away and the other was broken out of the box. That is why I wanted to save them.
          I am back in business.
          Thanks Again,

              i think a blade welder would work best for this, try to find a company that has one they may be willing to do it for a small fee.

                Glad to hear of your success.

                If you can post a picture or three.


                Heck of a lot easier than one might imagine.

                Let us know of the longevity you have with them?

                  Just grind both sides a bit thinner, put the ends in the jig, and then pull the lever, ZAP, its done.
