1) I bought some cheap track wheels for converting an early 80s road frame to fixed. the front hub is a sovos track hub. The solid axle diameter is too big for my fork dropouts! Is this expected? Can I take a dremel to the dropouts and widen them a little? The shortfall is very, very small, but enough that i cannot just jam the axle in there.

2) Chain line - how to adjust the horizontal position of the cog? by my estimate, i'm within 2mms of the dead on chainline with the cog flush against the hub. how can i get it outboard? with spacers? are there spacers with widths as little as 1mm?

3) any tricks for tightening the chain? no matter how hard i pull, i can't seem to lock down the axle as far back in the dropouts as i'd like...

Thanks! already read sheldonbrown.com cover to cover, but still have these questions! thanks!
