Pulley, Timing - Spindle, 9x20 Bench Lathe

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.

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.

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.
