For Draconic equipment I utilize a lot of the information from AEG's Dragons including the following:
*Skills Required*
Alchemy: New use = Organ Harvesting
Summary: Covers knowledge of how properties and uses of various magical substances, plants, and animals and how to properly gather them. Alchemy (DC 20) to harvest specific glands/organs/substances from a slain magical creature. Reduces cost of making alchemical substances using these items by 10%.
Craft: New use = Dragonsmithing
Summary: Dragons are such legendary and potent threats, and their corpses are so large and often composed of so many peices valuable to Wizards and Alchemists, that an entire trade has grown around the disposal, preservation, and sale of dragon parts. Dragonsmithing is the art of preserving dragon parts, refining organs and tanning hides, etc. Using this form of craft, a character can use any craft skill if it revolves around crafting items from a dragon's corpse. PC with 5+ ranks in Craft (Dragonsmithing) gains a +2 Synergy bonus when using any other Craft skill to work with materials gathered from a dragon. A PC with 5+ ranks in a Craft skill relevant to what he attempts to do with Dragonsmithing gains a +2 synergy bonus on his Craft (Dragonsmithing) check.
Special Note: In this instance (ie your request) this would refer to Craft (Weaponsmithing).
*Creation Feat*
Dragonsmithing [Item Creation]
You are a master of draconic anatomy and have acquired a comprehensive knowledge of the variety of magical weapons, armor and other items that can be created from a dragon's body.
Prerequisites: Caster level 3rd+, and Item Creation feat
Benefit: If you have access to a recently slain dragon, you can produce magical items for 25% less than the standard gp cost for creating the item. In addition, you gain a +2 competence bonus to any Craft check necessary to complete the item. However, if a dragon is aware of your chosen craft, it immediately treats you as hostile.
*Dragon Alchemy - Weapons Example*
Dragon Bone Weapons
Special: Dragons know "Dragon Bone" items on sight, DM treats Dragon reactions appropriately.
* Must have 8+ ranks in Craft (Weaponsmithing or Armorer), 5+ ranks in Craft (Dragonsmithing), and a set of Masterwork Tools.
* Medium Dragon = 1d6 tiny weapons
* Large Dragon = 1d8 small weapons (or 2d6 tiny)
* Huge Dragon = 1d8 medium weapons (or 2d8 small/tiny)
* Gargantuan/Colassal = 1d10 large weapons (or 2d8 medium, or 3d8 small/tiny)
* Weapons made with dragon bone are considered Masterwork and add a +1 to +3 bonus to enchantments (see specific rules for how this works).
