I have recently seen references(c.1870s)to "punched steel" barrels. Anyone have information on this?

I believe it is one in the same or very similar to the Deakin & Johnson process(if there is such) and some of the early French rifles were from a method of processing ingots like one would punch out a tyre.

Here's a snippet from 1868. I've seen it in other texts on Iron & Steel: The Chassepot rifles are all being made in this way, but another method known, as that of Deakin & Johnson is being introduced with considerable probability of its general adoption. In this process the ingots, after being hammered to about live inches in diameter, are cut into pieces of suitable weight for a gun barrel, and punched in the same manner as has been described for the punching of tires. The blanks so punched are heated and hammered, and then rolled over a mandril into a cylindrical tube about afoot in length, which is again heated and rolled over a mandril into a gun barrel. This process forms the subject of a patent although it is difficult to find anything in the process which is novel, except, possibly, in its limitation to gun barrels. It is applicable however either to cast steel or to Bessemer steel the latter being generally employed. http://books.google.com/books?id=bGaHxMA...rel&f=false1868 Kind Regards, Raimey rse

Don't know if this is one in the same or not: Punched Steel Tubes: It is stated that by a new German process steel tubes for boiler work are punched from the hot metal. A bar of steel is placed in a matrix of sufficient strength, and having a hole the exact diameter of the tube; then without allowing time for the steel to cool, a mandrel having a rounded end is forced lengthwise into the mass. Tubes nearly 8 inches in diameter are thus produced the pressure required to operate the mandrel being 180 tons. The tube is finished by drawing and redrawing to the required thickness. http://books.google.com/books?id=8SZLAAA...els&f=false1895 Kind Regards, Raimey rse

In the above Spirally Welded Tubes, most interesting to see how observant Heinrich Ehrhardt was on the pattern welded effort in Suhl & Zella Sankt Blasii. I'm sure he applied his vision to his patents based on his observations. Notes some effort in U.S. of A.??

Deakin & Johnson of Blisten - 1866
Spirally Welded Tubes:
The original Armstrong guns were made on a similar principle. A heated square bar was wound into a spiral on a revolving mandril and the coils then closed by hammering the block on end under a steam hammer; but except for sporting guns such methods are now abandoned. Indeed as early as 1866, Messrs Deakin & Johnson, of Bilston, were making weldless rifle barrels from a steel block about 1 inches diameter and 8 inches long, by punching a hole from each end under a steam hammer, and then rolling the blank presumably in the same way as weldless tubes are now rolled in the process of "rolling off" previously described. The old patterns of military rifle barrels having a bore over inch diameter were thus made until quite recently; but the barrels of the modern rifles, having bores only about half the size, must be drilled entirely out of the solid.

From my study of William Powell & Son guns, it appears they used
"punched steel" for shotgun barrels as early as 1872.

I don't see it, but Mick gives his offering has the term "Punched Steel" on the tubes? http://www.micksguns.com/whats%20new.htmabout 6th or 7th one down. Kind Regards, Raimey rse
