Current Projects chat and miscellany

Is it easy enough to get a crimp put in my Dolan's chainstay to give me a few more mm clearance for the 52t ring I have, or should I bite the bullet and try and find a 48-50t 135BCD track ring?

This will likely see some solid nerging but in a similar situation with a steel frame, I marked the offending area, covered it with a tea-towel to avoid knackering the paint and then hit it with a hammer until I had a dent I was happy with. It was a build for a friend so sadly no pics but it did the trick.
