Lubrication point?

Holding up the disassembled action frame, he wondered, “How did they machine this?” Pointing to a slot beneath the watertable, he said, “They were gracious enough to put a hole here so you can trap the cocking rod hammers to take the pressure off the hammer screws.”

That is not the hole that is referenced in this thread. Those holes are the ones on the bottom inside the action that are used to help remove the hammers and mainsprings from the action.

The fact that Brian has a cocking lever without the hole and since the pivot hole and the cocking rod hole are all that is required to orient the part for machining the visible hole when assembled in the action must be for lubrication. I think the part is forged, the 2 shaft holes drilled in a drill jig, the part was then finished on a profiler, and the oil hole could have been added when the shaft holes were drilled or after profiling. I doubt the part required heat treating.
