In 1908 the Hill Publishing Company published a series of kinks books that turned out to be very popular. All of the kinks information was selected from "American Machinist" magazine and came from practical suggestions by it's readers. Lots of good practical information for hobby machinists with manual machining tools.
The series included the following books:
I think I have most of these, today I am uploading, "Screw Thread Kinks" and "Toolmaking Kinks". If someone has interest in another title, message me and I will see if I have it.
Both the above books are available for download on my Books - Free Downloads page.
