Lathe chuck adapter
August 24, 2025
The adapter was of good quality and arrived well packaged. There's only one problem, but it's a big one. The end that threads onto the headstock was the wrong thread size. I must say though that I am not sure if the problem is on their end and someone sent the wrong adapter or if the fault is mine, in ordering the wrong one.

This adaptor fits perfectly on my 1950s era craftsman lathe in order to accept chuck for bowl turning.
