soft steel shafts or shafts plated with nickel usually have brass bearings. Most household ac motors have brass bearings.
Yeah, machining a small chunk of brass should be no problem for this thing. It also sounds easier than the idea I had: if you really want to do some metal casting, you could melt down some bronze welding rods in a small crucible. You could cast it in a small mold made of clay, plaster, casting sand may be best. Cuttle bone might not be deep enough. You could make the mold relief a little on the heavy side so that you could machine to tolerances.
