So lots of good stuff in the Winter 1954 PM Shop Notes. I have uploaded some of these projects before, including the tapping fixture below, but the resolutions were poor because they came from a Google scan. I am scanning lots of the stuff in this one, with better resolution and cleaned up much better.
Below is the cover, that neat tapping fixture, and a very nice article on threading with taps and dies. The tap and drill size tables are the most informative I have seen, and very usable compared to the eye straining tables you get with tap and die sets. Printing off a set on laminated paper, for my shop wall, is a must. How tight do you want your threads? These tables give different drill sizes for less than full threads.
