I would atleast snap ring the sprocket side and use a bolt/washer on the other side. If you don't have the resources you could always just buy the VersaChassis hex shaft:

What's your experience with the 0.251 ream on the encoder bore? I've wondered how close of a fit we'll want, and we haven't tested anything yet. How easily can you insert and remove the encoder, and how well does it stay engaged with the shaft?
