I have heard that this type of damage to the rim of a diamond blade can be repaired with a tig braze with a silicon bronze filler rod. And then grinding the repair down flush with the rest of the rim of the blade.

Happened to me last week with a chunk of agate. Fortunately the blade locked up, stopped the motor and the motor's overheat protection kicked in and shut it down. I was able to untangle the mess without blade or motor damage. But I sure pay attention when I hear funny noises while tightening the vise!

I wonder if that gap will hurt anything? I do see more fractures to the right of the gap in the first photo. Correct me if i am wrong but i am fairly sure they are there.

take a file and smooth (round) off that area, and you'll still be able to use the blade as long as it isn't bent. But remember, it will now cut you too.

Correct me if i am wrong but i am fairly sure they are there. rockpowell Yes there are fractures after the chunk out, but it feels quite solid, Did try and cut with it after an oil and new Fafnir bearings, there was a noise and slight vibration. So I went back to the old mk 303 blade. No noise, just to check the new bearing sound. Never thought of the blade beaning welded, Have a friend that could do that for me as the blade was new and only used for 3 mo. Will try it and let you know how it turns out. It was a 14" black covington. Thanks ! 1dave hunting buddy. |

You also need to oil that blade after you're finished to keep that rust off. Rust can weaken a blade rapidly.
