Forged Gun Barrel - Method 3

-Stock: 30” of 5/16” square bar (76cm of 8mm square bar) (I misspoke in the video) -Mandrel: 3/8” (10mm) round bar. This method was a pain in the butt, partly due to my makeshift method of wrapping the stock and the stock itself being square. The stock should have been rectangular. That being said, I feel it has produced a very strong barrel (due to the large amount of surface area that needed welding, it received double the amount of welding and shaping heats the other barrels received.) I forgot to shape it to an octagon cross section, and I should clarify what I meant when I said that the inside was smoother than I expected. It still retains its spirals, but they are not as deep as they initially were due to compression from welding of the barrel. I feel this method is good for both thick and thin barrel types. Because of the spiral wraps on the inside of the bore, more drilling/reaming will be needed than the Whitley method, though this may be helped by the insertion of a mandrel during welding.
