I'm building Jan Ritters flame eater engine engine. I changed the threaded fastener sizes from meteric to US standard imperal sizes. I was stumped why the external threads I was putting on the brass supports came out undersized and would pull out of the threaded holes in the cylinder. I then realized that I had used the wrong column in the threading table - minor diameter instead of major diameter. I think I now have a 6-32 instead of an 8-32. Now to cut off the threads and put in studs. DUH.
