Hi Bill
I have the Nova DVR and I have a good friend who has the Stubby750and I've turned on both. I've had the Nova about two years and I turn hollow forms and bowls for fun and furniture parts and architectural pieces for customers. I have added one bed section and my spindle length is about 36" max. Low speed torque about 50 rpms is good and I have cast iron legs that help in the weight dept. The Stubby is a whole different class of lathe. Engineering wise you willnever be able to wear it out. It primarly geared torward faceplate turning but is capable of spindle work up to about 36". It is more than capable of handling big wood(100kg. and up) with little problems. All I can tell you is that if you have the money and want a lathe to last a lifetime Stubby would be my first choice and Vicmarc would be my second. Check out the user groups on line. Call Stubby in the US and ask if someone near you has their lathe and ask them every question you can think of or see if you can pay a visit and turn on their lathe. Good luck and happy turning.
Regards
Randy
