Lily ★★★★★

The half nut lever fits perfectly into the SC4 assembly with no slop at all. Machining is clean and the locking wheel engages exactly as it should. Feels like a quality replacement that will hold up over time.

Michael D. ★★★★★

Never had a problem with the stock part, but this replacement feels a lot more solid once it's torqued down on the half nut. The lever action is crisp and it seats exactly where part #305 should on the SC4 diagram.

Ryan F. ★★★★★

Installed this locking wheel on my SC4 lathe and the half nut lever engages much more smoothly than the original. The knurled grip is a nice touch, makes adjustments easier without needing a tool.
