旋鈕把手，進給桿，9x20 桌上型車床

The threading on the bottom lined up perfectly with my lathe's power feed post, no wobble at all. It's a simple replacement but makes engaging the feed feel much more solid.

Finally, a knob that actually fits the power feed lever without shimming or filing. The threaded bottom is clean and mates up tight, so the lever feels solid again instead of wobbling. Was a bit skeptical about the plastic, but it’s held up fine through a few heavier cuts.

Installed this on my 9x20 lathe’s feed lever and it’s a perfect fit—the threading was smooth and tight right away. Makes the lever much easier to grip and operate during a cut.
