damascus- raised dent

Holeshot · 11-22-2011, 08:03 PM

Looking at a gh 1 frame that has had a dent pushed up to far. The barrel is slightly raised. Can it be pushed back down. Thanks Dave

Yes. Any competant gunsmith can do that, but the gunsmith you choose should be more skilled than the one who turned the dent into a bulge.
The trouble with a bulge is that it must be hammered down, which leaves marks on the barrel and then the barrel should be re-browned if you don't want the marks to show. With a dent, just raising it is usually all that is required with no refinishing. The bulge is probably a result of an overzealous user with a hydraulic dent raiser. Hydraulics have a lag time.

If you find someone with the right set of pin gages they can put that bulge back down to where it will be barely, if at all, noticeable. I use a leather or a plastic hammer for that and it doesn't leave any marks at all. I experimented with my pin gages on a pretty dented up Ithaca Flues damascus barrel and was amazed at what I was able to make completely disappear.

Thanks Richard & Bruce. The bad news is that someone touched it with a file after they over raised it. The good news is they didn't get to carried away. Brad could probably make it disappear, but the gun is a very nice original 1904 gh. I am not sure I want to refurbish it, but just touch it up. Pictures on GB 258608439.

Richard: What is a pin gauge and what else is it used for. Thomas

I made a pin gauge out of a 1/2 inch craftsman deepwell socket, added 2 pieces of painters tape and tapped into place on inside of bore. Used a plastic headed hammer, a piece of leather and a jenga block of wood that was laying around. Played with it until I could not feel the raise any longer and worked on smoothing out the previous workers tool marks. It is still noticable, but good enough that I can live with for a while. Dave

David, How far from the breech is this dent?

David, How far from the breech is this dent? Pin gauges are commonly used in the machining /toolmaking trade. They come in increments of .001" and are used for checking bore diameters and have several other uses in the inspection of machined parts.

Thomas, Here's a set of pin gauges. I use this set to measure 10ga bores/chokes and remove barrel dents.

The dent was about in the center in the 28 in. barrels. I used Richards leather idea and was impressed how well it worked.
