Hate to depress you even more but there were more than a few differing diameters of cottered axle made over the years. look out for older continental and Japanese stuff.
Not even going to mention cotter pin sizes....
I have an update on this one, I took the cranks to the LBS to check against an axle he had. Non drive side arm fitted fine, drive side wouldn't go on. Had a proper loo at it and it had some rust inside that I hadn't cleaned out. So off to work the next day and clean it out with some emery paper, try fitting it that night, still no go.
Get the verniers out and the drive side arm is 15.87mm diameter, where the NDS is 16.15. Hell. So take the crank to work again, and ran a 5/8" drill bit through the crank which took it out to 16.1mm. Get home tonight and the crank pops on beautifully .
Install the cotter pin, all goes well .
Spin crank arm, CLUNK.
Axle is too short . Why me, I haven't even got a beer to drown my sorrows with!
This bike has been so much hassle, this is just the latest after the original stem needing to be cut/blowtorched out, the powdercoaters stuffing up the masking of the BB and steerer, oh and after fitting the new headset the new stem won't go in for some reason .
