An easier way, especially for those who're on consoles, is to just level Smithing off materials you find. The simple/trivial act of not buying ingots from the vendors makes Smithing level at a much more reasonable pace.
I store equipment in the barrels at the Ironmaiden (I think) . Smithing equipment in one barrel and the stuff I plan to work on in the right one. After each mission, I stored stuff in the barrel and fast travel back until I get done. I would take trips loading down my follower (only items over 100gp) and we were off again. Then I would turn skins to leather, smelt what I have found to ingots...then I grab all items in both barrels - put on smithing equipment I have bought (gauntlets, amulet, ring) - drink a Smith potion - and go to work upgrading as fast as I can - first weapons rotate to the left and then use the table to upgrade armor. After I was done, I would put ingots, leather, and smithing equipment back in the left barrel and head out to sell what I now had - first at the blacksmith, the archer, my house, the merchant, then Arcadia - then head over to the Sky forge - then head back - put the rest in the RIGHT barrel and off to explore again.
I went up on the left side tree of smithing just to get glass and Dragon. Once I got dragon, I pretty much only make Dragon armor - that I upgrade and sell now.
I never enchanted any items, never "spun" creating any items - just upgraded things I found - then sold those.
You can push sales higher by buying stuff from them first - then turning around and selling bigger ticket items.
Seems to work well for me on the XBOX 360 - as Im level 45 and have 200+K gold
Im not metagaming or churning any smithing - just doing it when I need to sell my LOOT I have collected while exploring.
