[V] I need some help! I have a Bowser Mountian kit that needs to have the gear on the axle trued, or straightened. Does any one know how to do this, or know of a tool on the market that will do this for you? Thank you in advance for any help!
NFM is correct. NWSL makes the tools you need but if you aren’t a frequent scratchbuilder the necessary tooling is pretty expensive. If your problem is a oneoff and you are unlikely to be confronted with a similar in the future I would opt for having Bowser fix it.
