Yeah, I heard that they patched the "1000 iron daggers" trick a while back.
Smithing rises, like Alchemy, on the cost of the finish product or the rise of the cost if tempering. Since iron daggers don't cost much, it doesn't rise as much.
I make jewelry (transmute iron ore to silver or gold to what gems i have, then gold necklaces) until level 30 when I open the Dwemer perk, go to the Dwarven vault by Mzufit (sp), south of Windhelm (take carriage), then make Dwemer arrows if you have Dawnguard or Dwarven bows if you don't. Arrows need I wood per dwemer ingot, bows need 2 ingots per 1 iron. If you have Hearthfire, you want to save your iron ingots, so make arrows. Then go to Markarth, and get those ingots. Go south from Markarth down the road, take a right to follow the Orc stronghold, go left and there'll be a dwemer tower for some more. Make sure you can handled a bear (in your path) and saber tooth (not in your path). No hard critters to fight.
Make sure Warrior stone is activated and you're well-rested and the smithing bar will rise "1/3" faster.
Always buy iron ore in the stores.
Before you go into the Dwemer dungeons, buy a horse for the excessive weight. You don't have to always ride the horse, if you like to collect alchemy ingredients but you can fast travel to the location you're at and your horse will be there.
