Since its re-done right now, i thought i'd share some thoughts on dwarven technology.
Imo dwarves technologically are masters of BIG:
e.g. Big Cannons, Massive Siege Engines, Blast Furnaces, Great Pumps etc.
While gnomes can be more technologically advanced and create portable and intricate machinery, dwarves focus on big powerful lumbering hunks of metal, essentially overkills suited to mass production and mass destruction.
Of course, currently dwarves are already themed like that in MWDF but i would think that fleshing it out further benefits them and makes them more unique.
Thus they could co-design or share some thechnology with gnomes (how about gnomes and dwarves requiring each other's help in some massive designs? - dwarven metalworkers and masons cooperating with gnome tinkerers) and also have some designs of their own, maybe as efficient as the gnomish ones, but dwarves can only make the huge flavours of these.
Very vague, i know, but maybe you'd find it interesting.
