Found this web site that has old and new books and magazines on line for reading. Under the craft section there is some stuff on model making and machining, a lot of this is probably the same as what is available for downloading off of the Internet archive but there is some new stuff to. You have to do a search then scroll to the bottom of the screen to find the book or article you where after.
