Isabella ★★★★★

I was worried about finding the right replacement for my SC4 lathe, but this 120-tooth gear fit perfectly as part #73 with no modifications needed. The teeth mesh smoothly with the existing gears, and it's held up well through several hours of turning.

Brian ★★★★★

The 120-tooth gear was a perfect fit for my SC4 bench lathe—no wobble or slop. It engages smoothly and makes cleaner cuts than the old worn-out part it replaced.

Mia X. ★★★★★

Installed this on my SC4 and it meshes perfectly with the other gears—no wobble at all. Machining a stubborn brass rod went smoothly after the swap. Exactly what I needed for the setup.
