Thanks Steve, I do remember this style you mentioned and it was always hip-pocketed as a good working solution. Mine would be different in that it would be two pieces, dowel-pinned together, and probably a pair of 1/4" cap screws to clamp the two. The bore would be further relieved so only the rim would be gripped. I know you dislike extra screws, but I think in this case it'd be worth it, as the grip would be seriously strong.
