esto dice un grabador de los revolveres inoxidables Pietta

este es un grabador yankee comentando en un foro de grabado:
I would like this post added to the list of guns to avoid for engraving.
I just finished working on a pair of stainless steel 1858 Remington cap & ball replica revolvers made by Pietta. The frames of these guns were made of some of the worst metals that I have had the misfortune to engrave. Fortunately this was a very light coverage job because I would have gone crazy on a full coverage. I have engraved all kinds of stainless steel hanguns and while the cylinders can be very hard they are engraveable. I have never had a problem with any revolver frame so I made the mistake of not test cutting. Once I got into the first one I tried a magnet on it and not surprisingly it would not stick.
In this case it was not a problem of the metal being too hard but its inconsistancy in yeilding to the graver. The surface was fairly hard but when I got a few microns below the surface the tip wanted to go to China. I was constantly fighting to keep the tip in the cut without plowing in too deeply. By the time I was done my jaws ached from gritting my teeth. I have taken a vow not to bother engraving any stainless guns in the future because life is too short for such aggravation.
On the other hand the carbon steel cap & ball guns made by Pietta cut beautifully. I was once able to engrave two entire cylinders without once resharpening my graver and was able to make smoothly flared cuts with the greatest of ease.
I hope this post can save someone else from the nightmare of Pietta's stainless steel.

traducciendo, nos viene a decir lo que sabemos los grabadores, que los revolveres Pietta estan hechos con hierro de balcon (añadido mio), y deberiamos evitarlos para grabar.
En este caso se trata del Pietta INOX, el cual, al grabarlo, el grabador se encontro con el problema de inconsistencia total en el material a grabar, tengo experiencia en ello, me paso con los bronces de cierta pistola, mal fundidos.
lo que sucede es que por ser poroso, mal fundido e irregular, la punta del buril va hacia donde quiere y no es posible hacer un corte limpio.
ojo, se refiere, insisto, al modelo REMINTONG 1858 en inox, los de carbono, hechos tambien con hierro, mas que acero, graban bien, pues son muy blandos, pero el inox...el inox debe ser de calidad para grabar bien. Ser uniforme en grano.
es curioso los Uberti no dan esos problemas, ni los antiguos ASM, ni Los EUROARMS.
a mi juicio esta marca deberiamos relegarla al olvido.
Un saludo
