Hey folks.
I got myself a Reproduction supergoose, just to cruise around town. This nut on the bottom bracket keeps loosening during riding. I can do it up finger tight but when I try and tighten with a spanner it slips and feels like it will strip its thread. Is it assembled wrong or am I just not doing something correctly.
Cheers.

Might need a thinner washer between it and the bearing race. If it’s not tightening or feels like it not gripping it’s likely either A the lock nut has poor threads or B it’s not catching enough thread on the crank arm, so needs to tighten on a bit more.
Possibly worth trying loctite blue on the lock nut also. This was an issue on cheap 1pc cranks way back when as well.
It’s been a while with a 1pc crank… But I don’t think you need a washer, it’s meant to lock in the other “nut” so they’re tightening against each other which makes them stay. I don’t recall there ever being a washer on any of the ones I had.
