Hannah ★★★★★

I swapped in this timing pulley and it eliminated the belt slip I’d been fighting on my lathe; the machined teeth engage perfectly with the new-style drive. It’s a direct fit on the spindle without any modification.

Andrew ★★★★★

The bore fit the spindle perfectly on my SC50, and the teeth lined up with the belt on the first try—no shimming needed. The direct-drive swap feels noticeably quieter than the old setup.

John Z. ★★★★★

Took a gamble on this since my older 8.5x20 uses a different size, but the mounting holes lined right up and it's been spinning true for a week now. The machined teeth mesh cleanly with the belt, zero wobble at higher spindle speeds.
