So If I want to make a 1/4-24 thread on a part in the lathe I know that I turn it down to 1/4" and stick the 1/4-24 die in the tailstock holder. But what size do I turn for a 2-56, 4-40 or 10-32 thread? I have all the tap drill sizes for taps on my handy wall chart and the densely packed info sheet in my tap and die set but nothing for dies. Putting a 2-56 bolt in the caliper gives around .086 and a 4-40 is sorta about .112. Tap drill sizes for each numbered machine screw size don't help much since a tap drill is smaller than the nominal screw size. Must be a table of sizes for dies somewhere.
