Please help! I have all three heads of the flail but don't nkow how to assemble! I have visted with dwarven weaponsmith by the docks and he said that i dont' have anything that he can make. Also, what do i do with the pommel jewel of the equalizer?

There is a forge in Nalia castle, it looks like a big outdoor grill, and it's in the back (north wall) of the first floor near where you found one of the heads.
