I would be more than grateful if you would send me a copy of the magnetizer article to which this conversation refers. I have 2 x BTH Maggys, one of which is mine, and one belongs to an elderly friend, and they both have very weak magnets. I have worked with electronics for many years and I have a mill and lathe, so I feel quite confident that I will be able to build one. my email address is dm at carolynmaher dot com dot au. I would do this by PM, but for me at least the forum says they are disabled.
