so I should just leave it be? and try to sort out the chainline?
will it be hard to set up converting from a de-railure(sp?) to a single gear?
Not at all. The only issue you may have is needing to respace the hub. Many track hubs are 120mm and road frames tend to be 135mm. You can order formula/iro/phil in 135 mm, or just use a 7.5mm spacer on either side of a 120mm hub. The chainline should still be 42mm in the rear. In the front, the set-up will depend on the cranks you use. If you use the road cranks on the bike, you'll probably need to put the chainring in the inner spot (for a double, middle spot for a triple) using bmx style chainring bolts, and you might need a slightly shorter bb spindle. You'll just have to measure one you start building. Since you're planning to run ss and not fixed, chainline is not as crucial.
