Infinity Tools テーパードダブテールスプラインジグ用 真鍮ガイド

Finally a bushing that locks down without any wobble; the locking nut threads on cleanly and holds tight through the whole pass. My tapered splines come out crisp and consistent every time now.

The locking nut threads on smoothly and stays tight during use, no wobble at all. Makes precise dovetail cuts much easier than with the worn-out stock bushing I had been fighting with.

Swapped out the old bushing for this brass guide and the fit is noticeably tighter—no more wobble in the dovetail slots. The locking nut threads on smoothly, and it stays put even under heavy routing. Makes precise, consistent spline joints look effortless.
