Nishiki Conversion
Have had this laying around for a while, decided to convert it to SS for a while just for fun. Not sure of the year, but judging by the color, its mid 80s. 4130 Cro-mo with matching cro-mo fork.
Bio-pace chainring will be replaced since I'm not gonna run a tensioner. I know Sheldon said it can be done, but I had them on a fixed not to long ago, and it was a pain getting the tension correct. Anyway, any cosmetic suggestions. I kinda dig the color, just need to touch it up in spots. I have most parts laying around, just need to decide weather to stay with the 27" wheels it came with, or get long reach brakes and use 700c. What would you do?
Sorry pics suck, was taken with my crappy phone. And yes, its sitting on top my TV stand in the living room. I'm running out of room for bikes in this little place.

That frame looks almost exactly like the Giant Perigee I converted a number of years ago. The cliche "They're all made in the same factory in Japan" somewhat applied to many frames of that era.
It looks like the dropouts are technically horizontal but very short. Do they appear to have cutouts or a thinner section behind where the axle goes that almost screams "file me?" If so, the frame is almost exactly like my Giant.
I was able to file mine back about 3/8 of an inch - enough to make it viable for a fixed gear and even use a flip-flop hub with a one-tooth difference between cogs.
It's best to use a hand file and go slow. Or take the frame to a machine shop.

It does need to be filled, and am going to tackle that tonight. Have plenty of metal working experience, so I should be okay. If I can get it back enough (like 1/4" or so) it will be fixed, but if not I'm fine with SS. My only other SS is a mountie 29er, so a road one is in order. Did your giant originally come with 27" wheels. I have them, but need to rebuild them to better hubs (hub choice depends if I go fixed or not.) If I go fixed, I have a 700c wheelset already I can steal off my other bike I may use since i won't run brakes. It all comes down to the filling at this point.
The tubes look good inside, and there is only some cosmetic rust on the chain stays, so LBS is getting me some frame saver. To cover rust on chain stays (little chips from rocks and chain hitting) what would you suggest to stop it? I have thought of clear coat rustolium, but other options are accepted. Clear nail polish? I have had a hell of a time matching paint. Even took to body shop to see if they could match it. They couldn't. I don't want to repaint the whole frame, as this is the only spot that has damage.
Also, anyone know where I could get replacement decals that look the same. Or am I gonna have to make my own. No big deal, would just like originals.
