Yes, that's essentially how I set it up. But I've been pushing the angle to the high side, anticipating that it will yield towards the pull of the strings over time. I'm re-thinking that position, in light of the bushing-to-hole alignment issue - might try lower angles, at least on bushed pins. Thanks Ron, and all, for your insights.
