So I have acquired a GT Strike (I love the seatstays, so sue me), and I have noticed the welds are very large and thick, and would probably qualify for the "cottage cheese" look. Usually I wouldn't care but these welds are ridiculous, especially the ones that connect the seat-tube with the top-tube.
I was wondering if I could slap some goggles on and go to town on the welds with a Dremel? I mostly just want to get rid of the rippling effect in the welds and make them smooth, whether or not they meet flush with the tubes is of secondary concern. Also, I am unsure of what type of attachment to grind the welds, since the bike is aluminum. I would rather have something that would grind it down slowly so I don't cut my bike in half by accident or put a hole in a critical spot.
If this is above my head, would most welders be able to smooth them out?
They look really, REALLY bad.
