If you can find a blaze spawner in the nether (frontier or waste), build a blaze farm around it. Then, have blaze rods automatically sent to an auto-smelter for a consistent fuel source. That way, while you're sitting there collecting exp from killing blazes, you're fueling your smelter and smelting your cobble. By time you're finished, you'll have everything smelted, tons of blaze rods left over, and lots of exp!
