There should be a kind of small forges and quench tanks, which could be placed into guildhouses. With a weight of maybe 400, for example, for forges, a bit less for quench tanks, and small anvils, to forge alone when you don't want anyone to bother you. They could be obtained by events, or given to players after they prove to be good RPers, or whatev's, even buy them from Taemian, Gardr… This kind of smith equipment would have less slots than a normal forge, designed for personal use, with only 8 slots. Of course, not talking about furnaces and stock castings: if you want to smelt, go outside

Oh, and of course a normal table with a riveter.
This could be done by even an amateur 3D-artist, in about a few hours, imho. Opinions?
