I've had to get the sprocket spaced out a bit to get it closer. Front chainline is about 45mm and rear was 40.

Give up, how much is it?

5mm? not good. Excessive chain sprocket/cog wear, noisy drive chain

it might catch when the cranks flex under distress (hill climbing etc.)

miche BB's are adjustable by a few mill right? i'd push out those cranks or use a longer spindle and put the chainring on the inside of the spiders.

whats on the back that's giving you 40mm?

No, I said it ***was ***40, it won't be after spacing.

It's a Sovos hub with a Dura-Ace sprocket one side and some unknown make the other. If I pushed the chainset out further I would have run out of thread for the sprocket after I'd fitted a spacer behind it.

true, but one problem at the time...
