Die Tang Socket Redesign

I was working with a texturing die in the spare tire power hammer and noticed a small piece of metal fly off onto the floor. This is always a signal to stop immediately and do the forensic analysis to determine the origin and the consequence of the occurrence.

The piece was about an inch square and 14 gauge with some surface burnishing. Still it wasn’t immediately clear to me where it came from but after some searching I found it was the inner wall of one of the die tang sockets which broke out. Interestingly, it didn’t adversely effect the die performance.

After some further study I have concluded that the inner wall isn’t really needed on either end and and removing them will make it easier to insert and remove the dies.

In the diagram the result of removing the blue inner wall is illustrated in red.
