Over-tightened a tang screw once on your own custom build and your lost.(?)
Again, your going to have too re-fit the fractured tang after it's repaired with welding. It's NOT going to be an easy drop in.
Your photo's indicates that the tang screw inlet at the tang itself is deep
Best advice is keep the metal proud, then bring it down to the finish of the wood, with multiple applications /attempts at fitting.
Recovering the metal finish during a re-fit is much easier than scalding/repairing the finished wood stock during the repair of the flaw.
Ya fubar, ya fix it,, that's how ya learn
@IanH,, or just pay $$$,, you choose.
