Improve The Smelting Furnace

Improve The Smelting Furnace was going to be a quest in Van Buren, the canceled Fallout 3 by Black Isle Studios. It is located in the Furnace Caves.

Background
It'll take some convincing and trust, but if they let you shut down the furnace for a couple of days so you can make some upgrades, you can make it burn hotter and with less fuel, giving them better yields on their smelting.
