Have I been doing these wrong the whole time. I've always used 5/16 to drill the hole for a 3/8-10 thread tap. I haven't had an issue with my 3/8 shafts fitting on a modified pin.
I did a few at first like that too. My current shaft was done that way. 5/16 (0.312) will work because the threads will still cinch it down tight. Boring it to 0.308 is more accurate and I also use a tight fit tap. The shaft feels less sloppy while screwing it on. Both work but .308 is better because it is more accurate to the pin.
