I have a 4914 which just has a longer bed. I use to use mine often but then I picked up a Leblond. The Clausing actually has less wear but my Leblond has bigger dials and a taper attachment. The dials on the Leblond measures the diameter and the Clausing is radius so i have to remember that when I switch lathes.
The Clausing is belt driven so it's much quieter. Has flame harden ways and it should be 3 phase power. I added a VFD box and it works perfect. If the lathe is in good shape, it'll be a good one to learn on.
