I have done two different Bridgestone MB frames with a Steel Campy record headset with ghetto knurling. This method was suggested to me by a local mechanic with decades of experience. The bike shop owner who suggested epoxy or JB weld has done many on his own bikes, as he is a old MTB racer. The flower method is from a reputable frame builder over on the Velocipede forum. That method works great as I set one of my Bridgestones up with a aluminum cup headset without the locktight to see if it worked. It does.
