Default Re: seat post and handlebar stem

yeah, if anyone's interested, an imperial lathe (with it's orig imperial gearset) is well able to cut near-enough metric threads - i can't remember the tolerances except to say that no further investment on gearing would be required for pretty much any motorcycle work at all - the 'near enough' tolerances of an imperial lathe/std gearset turn out to be very very close indeed in theory & well and truly close enough for real-world practical purposes...

just in case anyone's thinking of buying an engineer's lathe

heck of a lot of milling ops can be done on the lathe too...

innit .... anyhow....
