At this time the smith is start to making steel bar,the method is making coal and iron.:two coal and one mine. Make sure the ratio is right, otherwise cast iron ingot will be made instead. I used to put 9 iron and 18 coal in my runescape pack. I’d like mention something here that the price of steel bar is 550-600ea. You can make these steel bar into plate bodies when you are at 48^th level. The price will come down when you sell one ,so you 'd better 10 sets in a line. But this is not a small sum of wealth. As long as your smith runescape account working hard,you will gain millions though selling armor. However , it is a small case compare with the later wealth you have.
Now you start to use mithril ore and coal ( you digged before) to make Mithril bar at the ratio1:4 when your smith accout get to 55^th level. And at the same time you should stick to make steel bar and steel plate bodies. It is too slow to get smith so that we should use steel to make them mianly. You may making mithril plate bodies when your smith account reachs 68^th level. You can sell it for about 3K rs money in store or 5K rs gold to players. Do these all the times in this way until reachs 86^th level.
At this time the mine acount in the desert could have reached 85^th . so do not dig for rune first and make it to dig for coal while another account is digging for mine in desert until your three mine accounts are all at 85^th level. All right,it is the produce time as smith accounts are 86^th and mine are 85^th. Put your mine three accounts in three different lines to dig for rune mine while your smith accounts are buying coal(do not waste time digging,it is clever to use money to make runescape easy money). It is time for you to compose a chopper now.  use the runite ore and coal at the ratio of 1:8 to compose a rune bar and then make a rune bar  into a chooper with some mine. You know the price of a chooper and the price will rise in a short time. You can make the whole armor when your smith account get to the 99^th level.~_~
