Hello, can someone please help me out as I am stuck on the crafting tutorial. I am on the last quest where they want you to go to a Assembly bench to put together(upgrade) a saw.

When I go there I have the "ranger" drop down under Assembly but nothing else under that... So the question is how do I upgrade the saw?

More information:
quest name: Artificer Training: Assembly
quest giver: Ulgrenda Remkros
starting map: Halgarad

Thanks,
Zabulon
