I have a set of drivers from a tyco 0-8-0 that I need to remove the drive arms from. On two sets of drivers, the nut the the bolt screws into are spinning when I turn the bolt. Any ideas of how to stabilize the nut so I can remove the bolt? I thought of jambing an xacto knife blade between the nut and the plastic on the wheel but don't want to damage the wheel.
Any thoughts are appreciated!
