damascus- raised dent

[Holeshot]

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.
