I am a lvl 17 Blacksmith, closing in on 18. I have looked at the recipes up through like lvl 26, there is absolutely no chain what-so-ever. There was talk a long time ago about their possibly being some med armor available to Armorsmiths, but I wouldn't keep my hopes up.
99% of all the armor you can make as an Armorsmith will be Heavy, Plate Armor (aka, tanks and CLR's only).
I would reccommend changing to outfitter, or taking up Weaponsmithing if you plan on making gear for yourself. As being an Armorsmith won't get you very far from what I have seen.
