Problem with fastlane diff cups

[maxxdude1234]

I believe Mike (the owner of rc-monster) was talking to fastlane machine about the problem. Don't know if the problem has been fixed or not.

If it hasn't yet, a dremel would do the job in a second (providing you have one - I don't so holding the spider shaft in pliers and filing in on concrete was the only answer). If you have a decent set of hand file, they should do the job. Other than that you can buy an aluminium oxide grinding tool from anywhere for about 1$, chuck that in a drill and off you go. But bear in mind you will need an extra pair of hands or a vice to do this....
