14X1.25 VS 9/16X20 have essentially the same thread pitch,it is the diameter that is different thus hard to thread a ENG pedal into FRENCH while other way is sloppy. When using an ENG pedal on a FRENCH threaded arm you are basically using what is the equivalent to a FULL ROLL tap(which rolls threads on instead of cutting them) to form new threads thus I am pretty sure you would not see any "SHAVINGS" The converse would be FRENCH in ENGLISH you would be pulling the threading out and sure might see something come out with your pedal!

There is something inherently creepy about loose threads and I would advise against using a undersize pedal with any crankset, that said I would think the vision of the resulting injury would cause everyone to pause.

machinist types who disagree can take it off list or into the alley but I think we have beat this thing to death twice.................................
