Current Projects chat and miscellany

there is not much thread to play with on the non drive side cup as is, so i'd only be able to space it over maybe half a mm. Any ideas, other than filing the back edges of the spider a little, which i'd rather avoid doing if i can.

I've got some 0.4mm stainless steel spacers which I had manufactured for sprocket spacing. Unfortunately, they cost me £40/10 to have made, so I'd have to charge you £5 each if you want one or two. For whole millimetre spacing, some of the single speed spacer kits come with 1mm spacers, I think.
