All period three piece hubs are quite easily separated - warm the hubs in an oven and the carefully with a wooden drift knock the flanges off the barrels. Refitting is a reverse of removal - its all really quite straightforward. ++++++++++ I defer to none in my admiration for Hilary's knowledge, but I know at least one exception: The (aluminum) right flange of the Schwinn Paramount rear hub has the same 1.37" x 24tpi threading as the fixed cog (or FW), so it is spun into place. Then the (aluminum)left flange is pushed on so its spoke holes are centered between those of the fully tightened right flange. The barrel is chromed steel, with the bearing cups cut in and ground. I would have expected this assembly method on other 3-piece rear hubs, too, but haven't disassembled any others.
