Safe to file dropouts?

Hi hipsters (someone in the mech forum told me to "Ask the hipsters in the FG/SS forum"),

Hi, I'm in the process of converting my hardtail RockHopper into a fixie.

It has horizontal dropouts, but as you can see, they're not exactly like they ideally. Is it safe to file these dropouts to make them into regular horizontal dropouts or would that be extremely dangerous and stupid?

File away. Specialized probably just filled the dropouts with brass anyway.

Safe is a dangerous word. How safe is good enough for you?

I would not do it, if that was my bike....but hey, I'm a mechanical engineer....what do I know about fatigue failure, stress concentration factors, and broken frames/bones

Safe as in "engineers think it's safe when the lawyers aren't in the room".

You might want to check out the eccentric ENO hubs. This will be MUCH safer than filing away at your dropouts.
