Bumping this to ask: where can I get a crank remover thread (22mm) cut into a crank? The taps cost about £60 a set - but I feel certain I wouldn't get it straight, needs a fixed tooling set up, right?
I have these nice early 80s pair of cranks with matchy rings, unused, one is (strangely) unfinished. Rang the original manufacturer (Cliff at Royce) who mentioned that sometimes various old parts surface that went missing from his workshop way back when. Which was a bit awkward ... though I bought them in good faith from a well known seller of vintage bikes.
For ages I've been thinking they were stripped ... really really stripped. But of course not, there's no remnant of thread. The ID where it's missing is correct for remover threading (21mm) so this confirms it's unfinished. Also, there's a faintly rough edge at the entry to the pedal thread, so I guess that is missing a little bevelling type job too.
Please nobody say 'use a bearing puller if you want to remove it'. Mainly because I feel like that will be a bit damaging.
