The Boy Mechanic, c1930 Free for download
the following is OCR text from the scanned book, the link above shows 3 items, books one and two, the first item, from Project Gutenberg is a duplicate of one or two, but not worth downloading. 700 projects, which can be updated to use modern materials and used as the basis of an Instructable. I guess from memory the book is from the 1930's as I have an original edition I bought second hand from a library in the '60s.
