2,160 x Cannonball (447,120)
After completion of Dwarf Cannon, players can smith cannonballs, which is profitable since one steel bar at 553 coins produces four cannonballs worth 828 coins total, thus 275 coins profit. Depending on which furnace the player chooses, he or she can produce between 2160 and 2400 cannonballs in an hour. That means the profit margin falls between 148,500 and 165,000 hourly.
Edgeville furnace is the closest furnace to a bank, and it has no requirements, but the others do. Neitiznot is the second closest, but it requires The Fremennik Isles. Port Phasmatys is third and requires two Ecto-tokens for entry unless the player has done Ghosts Ahoy.
