I have a SS bike I set up with a spare Sugino AT triple crankset. This crank used spacers and long bolts to attach the inner ring, so there are no cast protrusions to run into the chainstay when the crank is tucked in closer.

I flipped the B.B. axle around and put the ring on the inner (middle) position and it lined up quite nicely.

Try it out.

And Jeff, chainset is the commonly used name for a crankset in Britain. They are even reffered to as chain hangers or just hangers in some places. The Brits also refer to derailluers as mechs, etc....
