bought a few NJS frames a few months ago and finally get downtime to begin a winter project

don't have any experience with track bikes but just found out NJS frames use 110 x 8mm axles

read on a old post almost 10 years ago where they would just file down one side of the axle thread to make it fit

I have some origin8 wheels I'm using which are flipflop and have 120 x 10mm axles

couldn't find aftermarket 120 x 8mm axles, though there are plenty for the front

any thoughts on grinding down 20% of an axle? are there other options

I'm using a 1" carbon threadless fork so it will accept 10mm in the front
