Customer Reviews (4.8 / 5 · 5 reviews)

Charlotte ★★★★★

Finally I can mount my big 5" chuck on the South Bend without any wobble — the cast iron feels substantial and the 1"-10 thread engagement is smooth and tight.

Ruby I. ★★★★★

Fits my 5-inch chuck perfectly on the 1"-10 spindle thread, and the cast iron is machined clean enough that I didn't have to file anything down. Screwed on smooth and snug, no wobble when I took a test cut.

David ★★★★★

The 5-inch diameter fits my backing plate perfectly, and the 1"-10 thread spun on without any binding. It gives my older lathe a nice solid mount for the new chuck.
