I had a cro-moly steel frame (Bridgestone XO-3) frame powder coated a while back, and I'm finally getting around to re-assembling the bike. I have found that the nut for the seat post bolt no longer fits in the seat tube lug. Has anyone had this problem? I don't want to hammer or force the nut in there; I don't want to break anything. Would it be advisable to bore out a bit of the powder coat with a Dremel tool to make the receptacle bigger?

Thanks, I'll try the Dremel tool on that seat post bolt opening. The headset and bottom bracket both went on just fine, so I believe the powder coating shop covered those openings. When you say "proper sized tap," is that some special tool that's used to re-thread braze-ons and mounts? I screwed in some M4 bolts in the rack and fender mounts. A little tight, but they went in... Thanks for your information.
Hey, I hate to jump in on these questions but I'm having a bugger of an issue with my newish LHT and its rear rack mounts.
The mount in question is on the drivetrain side and after frustratingly trying to mount a rack, I peered inside and realized there was a lot of paint on there and no grooves. Was told to get it tapped and had a shop do it, but still cannot get the screw in there. I've tried a couple times, just to make sure it isn't my frustration (the rack will mount on the otherside, no prob, and the fender mounts are fine). I looked again and it SEEMS like it is almost half-tapped? Would this be possible? And would I do more damage if I go buy a cheap set to work my way in? (I've been putting it off because I don't know if its a good idea).
Thanks ya'll-- I really do appreciate the info on taps/dies. My casual cyclist/former plane mechanic pa seems to think it'd be easy enough to do on my own, so.
Feel free to disregard my comment, but if a shop tapped the rack mount for you, and the bolt is still not going in, I'd take it back to the shop again and ask them to do it over (for free). When I've had things tapped at a shop, they've always made sure the bolt fit in when finishing the job (to avoid exactly what happened to you). The shop should have done that for you here.
