yes I converted all threads to metric the one good thing about metric is thread sizes only two
worked in the aircraft industry many moons ago dealt with Europe usa and this country complete nightmare with threads metric unc ba bsf etc tapping size clearance size drills ,taps and dies storing all these
worked in building trade for the last 30 years doors all still in inches we have never gone metric just converting inches to metric
got back in to engineering making models 2years ago still work in English but use metric threads
one set of taps and dies not boxes of English sizes
sorry for the moan thanks Geoff
