I need to revisit this a second, the pins on my Flues 20 are dragging on the primers making it very difficult to open the gun.

I believe you guys (Jim Legg I think) helped me to determine it has to do with the cocking rods not pulling the hammers back soon enough, i.e. the timing is off.

What I don't remember is which one is more likely to wear, the rods or the hammers?


Thanks, Rob

Do you have both? Levers can usually be bent cold and/or rods can be peened cold to make them longer. Get 'er done. A tiny bit at a time. Go too far and you'll probably get light hammer strikes. JL

Sorry Jim, I meant the rods or hammers. The rods bear on the hammers, which is more likely to wear?


Thanks, Rob

RR-The Flues has no cocking rods. The cocking slide on the barrel lump bears directly on the hammer toes. Check the cocking slide for wear/looseness, although I think it's unlikely. Excess firing pin protrusion could also be part of the problem.

I see what you mean about no rods. But what would cause the pins to "suddenly" elongate?

Did the problem start suddenly? If the pins do not protrude excessively when held there by the hammers being down, you have to do whatever is necessary to start the recocking process sooner. I'd strongly suggest getting the gun to a gunsmith who understands doubles. This is not a job for someone who has great difficulty understanding the mechanics involved. JL

Jim, I don't think I'll have great difficulty understanding the mechanics involved.

I just want to get a handle on it before I open the patient up.

The gun has gotten hard to open, I don't see the pins protruding excessivly, one's .055" and the other .050., is that excessive?

I also notice the forend moves slightly away from the barrels what the toplever is pushed and since the forend iron also acts upon the cocking slide something may be worn here.

I don't want to remove the hammers unless absolutely necessary.


Thanks, Rob

Hi Rob,
Your observation that the forend moves away from the barrels might be the answer. I don't know what the Flues' parts look like but many doubles use the forend iron to operate the cocking mechanism. You might need to add metal, by peening, to the forend iron slot where the barrel lug goes through it, to get the forend iron back snug-but-free agains the front of the receiver. This may be where you are losing the cocking drive. JL

On the flues, at least the field grade, the cocking lever goes through the bbl lug at an angle downard as it goes to the rear to catch under the toes of the hammers. It is held there by the forend iron, removal of the forend allowing disassembly. If the forend is not being held firmly as Jim said, it could be allowing movment of the bbls before starting to cock the gun.

You might want to check the forend hanger lug to be sure you haven't broke the solder joint. You may or may not be able to wiggle it by hand if it is loose. This could be why you see the forend move when it is under load(cocking).
