Removing Revolver Barrel

[sign216]

I tried to remove this Iver Johnson barrel, but it won't budge. Wrapped w leather, used Kroil, put it in a vise, and twisted the frame....the barrel still turned with unscrewing.

Any ideas? Apply a torch?

How about trying a barrel vise? Open this link to the Brownells page to see various ones, and perhaps you could cobble something together to work.

Looks to have a pin in it from the photo. Lower left corner area.

What are you trying to save? Barrel, frame, or both?

Funny, I don't see a pin close enough to the barrel to have anything to do with it. Rather, there's a lever near the pin which is probably retained by said pin.

I don't understand.
Looks like it turned, keep going?

I venture to imagine that the barrel turned in whatever was clamping it. Thus, the need for a better barrel clamp arrangement.

Your looking too low. On the flat section about 3/4 down I'm seeing a pin ~ 1/8" which is in the correct position to secure the barrel.

Sure enough there's a pin. No, wait, it's a spot on my monitor. Your eyes are better than mine because I see only the one pin which is too low on the frame to prevent the barrel from turning.

Cutting torch.

I think he is referring to the spot indicated by the red arrow

If one looks at the Numrich exploded parts drawing for the closest revolver to this one, there is nothing which could be described or assumed to be a barrel retaining pin. In addition, that blemish on the frame doesn't look like any pin I ever saw, regardless of age. Some gently cleaning, and perhaps some Liquid Wrench, could either remove the spot, or show what it really is. Pins are round.
In any case, some kind of barrel wrench is going to be needed.

Something is needed to support the frame before torque is applied to the barrel. A twisted frame needs to be avoided.

Soak in kroil penetrating oil for a week.

I believe you are correct. Looks more like a plated-over flaw in the frame. If by chance (or NO chance) it is a pin it would need to be a through pin, and visible on the other side also.

Agreed. It looked like a blemish to me too when I zoomed in, but it is hard to tell on a low res web image.

 

[Blue68f100]

Yes, That is what I was seeing. The other side will confirm or not.

It's also possible that LocTite was used and heat will need to be applied to break it loose. Need to get to the 400-450F range for it to release.

I have never needed to remove one of those. Are you turning it the correct direction? IIRC some barrels are reverse thread. Does anyone know what IJ uses?
