Steven ★★★★★

The six holes lined up perfectly with my 3-jaw chuck, and the threads engaged smoothly—no wrestling or cross-threading. The spacer washer was a nice touch for the Taig spindle, though I had to double-check which side to use it on.

Robert ★★★★★

The included spacer washer was just what I needed to fit this on my Taig spindle, and the 3/4"-16 threads engaged smoothly. The whole thing feels solidly machined and my new chuck mounts without any wobble.

Lucy ★★★★★

The six holes lined up perfectly with my lathe's backplate threads, and the included spacer washer was just what I needed for the Taig setup. After mounting the 3-jaw chuck, I checked runout and it's under 0.001" right out of the box.
