Lubrication point?

[Mike of the Mountain]

Was it used for the machining process?

Thanks everyone. So I called Larry DelGrego today and asked him about the pinhole on the cocking cam. He said it's a recess for a tiny pin that's part of the cocking mechanism. I asked if it was a good idea to put an occasional drop of oil down there. He said you could but don't overdo it and don't let the belly of the action and the cocking slide get gummed up with dirt/powder residue.

To keep the action clean and oiled he recommends removing the barrels and spraying BreakFree CLP into the action. Then allow to dry by propping the gunstock up so the solvent wont run into the wood.

Good info. Thanks. Party on Garth!!

That's news to me....

Just when I was about to start what would become a 3 page inquiry into how much of what sort of oil should be used.

[Craig Budgeon]

I don't think I will use oil in that hole unless I detect a slight resistance in the cocking lever. When I do use the hole to lubricate the cocking lever I will mount the action in my vise so that the oil gravitates toward the hinge pin rather than the wood.

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.”

This excerpt taken from a recent article in Sporting Classics Daily. Could this be the answer?

[Craig Budgeon]

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.

Yeah, doesn't make any sense to me either. that hole goes directly into the axle pin hole perpendicular to it. Nothing is inserted into it and nothing relies on it. And, like I previously mentioned, I do have some used examples here that do not have the hole in it at all.
