Forming Roller still in the machine.
Roller split in half.
Close-up view of the crack.
The outer edge reveals that this roller was cracked for some time before it let go.
This is evident from the very polished outer edge that was "cleaned up" by the abrasion from debris in the crack.
Poor quality key-steel used in the key way allowed the roller to slip on the shaft and wear a bad grove.
This shaft was replaced.
The completed and rebuilt shaft with new key steel in all the rollers.
Notice the new Forming Roller, the old one sits on the wooden pallet to the right.
