Singlespeed & Fixed Gear - Katakura silk big problem

I am new here but have frequently viewed all the great helpful hints. Well now I have my own problem and I hope someone has a fix for me. I have a Katakura silk frame the serial number is: KE06165. I don't know the frames vintage. I wanted to turn the bike into a fixie. But I have a problem with the rear dropout sizing. The wheels I bought are 9mm front axle and a 10mm rear axle Velocity deep v's. The rear dropout will not accept the 10mm rear axle. I just had the frame powder coated and really don't want to file the dropout. Does anyone know of a fixed or single speed hub that has a 9mm axle? Or any idea on how to convert a formula type hub to accept a 9mm axle? Also my dropout spacing is 126mm. I love the frame it is so light, and strong. Thanks in advance. Bob

1mm? I'd just file it.

Thanks, I was hoping not to have too do that. Can powder coating be reapplied to the area I file?

You are filing your dropouts, which is where your wheel axle is going be and it will be scratched a lot by the nuts. Why bother keeping them nice and clean?

no, the frame will be doomed for ever.

Okay I am being anal. It's new too me. Like a new born....lol. I am gonna file it tomorrow. Thanks all for your help.

Yeah, actually, I think it looks better to have a strip on the dropouts that isn't painted, this looks cleaner than the nuts inevitably scratching the paint all up.

This will be a pretty simple job, but be careful and don't get impatient... you can't put material back, and you will feel really stupid later if you **** something up. I would only file the bottom of each dropout, and maybe make or find a 10mm thick rectangular object that you can easily check your work with along the entire length of the dropout. Just putting in the wheel to check will be a pain in the ass compared to popping in something small, and you won't be able to easily check one dropout at a time.

Start slow. End slow.

Too ez to mess up

Damn, that is a nice frame, why not sell it so that someone can have a nice road bike and you can use the funds to buy a Kilo TT?

This is true but not many people in the Chicago area even know what a Katakura silk frame is or how special it is. Most people would just want to give me $100 at most.
