@llbroadwell what tool do you use to re-attach the spring clip ring that holds the sprocket to a sturmy Archer 5 speed hub?

It appears to have come off on that recumbent and now the sprocket is super wobbly

Circlip - Wikipedia

@HelenOfKent @llbroadwell essentially... Its a large circlip without the rings on the end to use with a pair of circlip pliers
And it's round in Cross section instead of flat
@HelenOfKent @Dasy2k1 usually with the Sturmey circlips they can be put back on with your fingers and a flathead screwdriver! fiddly but doable
