Unless go and see the lathe, hear and see it run through all speeds not sure can help you decide. This lathe very easy to fix, even though not being made anymore.
At one time chuck threaded insert were easy to find for that lathe, now not so sure. Headstock has MT-3 spindle and 1½" x 8 TPI and tailstock MT-2.
Now only chuck know you can buy that has a threaded insert ( 0302 1 ½" – 8 RH Conover) is Oneway Stronghold. Do not know if Nova or Vicmarc chucks still offer a threaded insert that size.
