It's recommended that the player is at least level 74 smithing to do this method since at that level you have a 10% chance of doubling a bar without using any resources while smelting. If the player is at level 77 smithing they make bars 50% faster. It should take around 52 seconds to make an inventory of Necronium bars, deposit them into your metal bank and then start the process over again. This makes it possible to smith 1,953 bars an hour and with the 10% chance of doubling the bar while smelting you get, on average, 2148 bars an hour.
