Mart, A talented man such as yourself will have absolutely no trouble building up the thrust faces. As I mentioned above, use a big soldering iron [more control that using a torch]; you don't want to damage the existing bearing material that the journal runs on. I use 'Fluxite' paste [made in England, so you should be able to source it easily], NOT an acid based flux [spirits of salts etc]. It'll build up real easy; like, the faces are already tinned for all accounts. Practice on an old bearing first? Good luck!
