At 3750 pounds, I can't imagine that it will be as rigid as a 1660 lathe could be. Most Euro/Japanese/Korean lathes in that size range are in the 5000-6000+ pound range with a beefier D1-8 spindle. It has cast iron plinths, which is great, but they can't be terribly thick at that weight. It'll be interesting to see how it holds up. Will have to tune in to see how it runs. Used to subscribe to his channel, but in the past year or so, the episodes have become like mini infomercials.
