Sounds like a workable thing to me Jon, thanks. How is that sintered powder in terms of making a keyway in it, considering I don't have an appropriate broach? Yet... What I have been doing is making miniature taperlock setups, which when pulled up snug enough, do not need a key. That however isn't practicle for lack on room so it will have to be keyed.
