How to reach Iron Forgeman

I am doing the ZB from several days ago, Iron Forgeman, and cant get past the gates to reach him. I have tried using the Master gears to open them and nothing happens. I have basically vanquished Sorrows Furnace and have been everywhere that I can imagine and still cant enter the room where the Iron Forgeman is located. Any suggestions on how to proceed?

You need to do the Sorrow's furnace quests. You gain access during the Final assault quest.

Budger should be following you, blow the gates with the kegs he gives.

Assuming you're on Final Assault and helped the others with To Sorrow's Furnace.

PS. All party members must be on Final Assault if you're getting help.

I don't think all party members have to have the Final Assault quest IIRC (Unless they changed it). Just make sure Budger follows you...sometimes he gets stuck along the way.

Suggestion
Do the Black Moa chick quest at the same time.
If your going all that way you might as well have another minipet to put in the hom
