I've noticed that the trainers in SW and IF for Armorsmiths have no items for levels 48-65.  Is there a trainer I need to find so I can make these items?  if so where?  if not do I just have to buy them?  If the trainer is in outlands please don't abbreviate locations as I've not been there and am still a newb to WoW.  Any information is helpful.  thank you very much.  BS 255

sadly you need to by the few plans off AH, but there is very few. The Thorium set is 48-55 and then the fel iron set is low 60s.

Go to gadgetzen and talk to the dwarf by the anvil for imperial plate set for the easiest skill ups. Despite using the word easiest, I am not implying that it's easy, in fact it's quite long and tedious.

To get the Imperial plate pieces you have to trade him khorium also, the belt and bracers are the lowest lvl to start grinding out first too. ten thorium per plan i think up to 50 thorium for chest. My lvl 70 has his hearth set to there still just cause thorium sells good gonna have to get aLOT GL
I wish i would have amde my paly a 49 twink longer and used the earthforged armorsmith only gear along with the pvp gear
