Hello this is from an old post started by Doran. The information is from Basra. Finally took the time to actually get my Legendary Smith a few months ago. This is how I did it. Don't forget the Salvage Bag.
Remember to craft in a Salvage Bag with the tailor & smith items, to save time recycling/salvaging.
For Blacksmith, if you have 105 mining and craft royal circlets, it should take about 10-12 thousand ingots. You can switch to boomerangs after 110 (if the account has SA), but the advantage of sticking with the Royal Circlets is that you can get 100-120 items crafted before having to recycle, while the Boomerangs require you to recycle twice as often.
