I have this crack in my chuck and I'm wondering what to do. It's a Union 4 jaw 6 inch 6628. I'm guessing it was dropped some time ago. It functions okay as far as I can tell. I was able to chuck and center a 1.5 inch round bar within 0.001 all along about a a 4 inch length of cantilevered bar. And the faces of the jaws are within 0.002 when engaged with a work piece.
The options I see;
Any other suggestions or comments on either option or any other options to consider? If welding is a recommended can anyone tell what material this might be and the recommended filler rod and process?

The options I see;
- Leave it alone.
- Weld it up with no filler
- Gouge it out with a carbide burr and weld it up
