Weaponsmith G10:
Craft 10 Weapons

To craft weapons, you first need to build a Weapon Workshop which will require you to have at least 22 dwellers in your vault. After you have built the workshop, assign some dwellers there to craft the weapon, select a blueprint that you have the necessary materials to build and then click build. If you don’t have materials then you can just scrap other weapons or armor to get them. Just build 10 weapons and this achievement will unlock.
