I won a set of Rotor 3D cranks off eBay where the NDS arm is damaged slightly. The thread for the binder bolt is stripped. Poking a biro in reveals confirms this. Would tapping it out to the next M-size up be a good enough solution?
I've never tapped a hole in my life.
Maybe a safer option would be a longer bolt with a lock nut. The bolt going through the existing stripped thread part of the arm.
