Well patman, this morning I went to lowe,s and saw a chart #10 = 0.190 and I knew the 3/16th was 0.1875 so I figured when Dumas says 3/16th shaft with 10-32 thread they really mean 3/16th shaft with a die of 10-32, used to make the threads. I wanted to verify this when I got home and found you "allready" vearified this to a tee, thank you.
I have two more questians:

Do I have to use the $4.19 cutting fulid, or can I use something else like oil, ect.

Will the die stay perpendicular to the shaft due to = friction or, do I just have to be very carefull. Thanks, Randy.
