I picked up an 80's Bianchi mid to low end frame at a bicycle junk yard and I'm trying to decide if it's worth saving. It has deraillers, a head set, cranks and pedals but I'd do a fixie or singlespeed conversion. It seems OK, but it looks like it had a nasty chain suck and I'm wondering if the damage is enough to make it unsafe. I've cleaned off the rust with some naval jelly and a wire brush and attached some pictures. What do you think?

Oh, and one more thing. It really is that awful lavendar mist color. The pink globs are just naval jelly residue.

You didn't show the most important part. If the frame has horizontal dropouts, I'd repaint it and build it into a fixie for sure. If the dropouts are vertical, I'd be a lot less enthuiastic about it.

If you have room, time, and budget for it, it is probably worth fooling around or experimenting with. Even if the chainstay eventually cracks (been there ... done that with a Peugeot UO-8), the failure should be medically benign to the rider.

stick the flat edges of the cup in a bench vise, and use the frame to twist it off. this method will remove the meanest of fixed cups in a matter of seconds, instead of hours with the box-end wrench and hammer, or whatever method you try.

My LBS tried that. If I recall the flats of the cup were very thin so there wasn't very much metal to grab onto. Then they used some professional looking tool and with two people and a huge leverage bar couldn't get it loose. I ended up using Sheldon Brown's method (http://www.sheldonbrown.com/tooltips/bbcups.html) at home to get it off. I had to put the bike on the trainer, sit on the saddle, and use leg power to break it loose.
