    How about a straight knurl on the shaft for the nylon gear? Thats what I usually bind when I salvaging parts.

    The straight knurl is common with plastic as Corbettprime suggests, a little difficult to achieve on a small shaft. It might be possible with scissor type knurls and supporting the shaft at both ends.
