Daniel ★★★★★

I was worried the replacement shaft wouldn't line up perfectly with my existing gears, but the precision machining on this one made it a drop-in fit. The keyway slots were exactly where they needed to be, so my lathe is back to cutting threads smoothly.

Carter X. ★★★★★

The threads are cut clean and it fits onto the B and C gears without any wobble, so the whole train runs smooth again. Took me about ten minutes to swap, and now my machine is back to factory spec.

Adam G. ★★★★★

Had to swap out my old one after the teeth wore down, and this replacement seats perfectly with no wobble. The splined end fits the B gear as cleanly as the original, so my feed rates are back to normal. Exactly what the old machine needed.
