Albion EJ Final drive sprocket 17T

[R]

I used something like that to have a sprocket "rebanded".
They machined away the blank's inner, and shrank/welded the circle of teeth onto the old ground-down sprocket's splined hub.
And heated and oil dipped it.

And used a bigger blank, for someone to retooth a cush drive hub for me.
