I crafted the needed items, have them all in my backpack and he won't accept them and there is no icon above his head. As soon as i completed the crafting portion of the quest, the quest disappeared and I can't find it in my log.
1) Make sure you crafted the correct item 2) Make sure you crafted TWO of them 3) Make sure they are both in your backpack when you go to Wul'yam 4) Check if you need to talk to someone else now (like Felicia in Marleybone)

He doesn't take them out of your backpack so you will still have the items. The best way to find out if the quest got turned in is to see if you have the next crafting quest in your log. It should say for you to go to Marleybone and talk to Felicia Worthington with the quest "Marleybone Calling"
