Jury Rigger

 is an achievement in Fallout: New Vegas which is awarded for successfully repairing 30 items. An easy way to accomplish this is by wiping out a location with many NPCs using similar weapons. Then, simply repair all the weapons together to get the achievement. Also, the Jury Rigging perk makes this achievement much easier, because it allows you to repair items with loosely similar items, instead of needing to find the exact same weapon/set of armor to repair together.
