I also see that, at 662 lbs, the shipping weight is 115 lbs heavier than the G0733. So you may be right about the engineers beefing things up. Adding ballast to the base should bring running weight to near or above 1000 lbs. Like you, I added ballast to my G0733. I was able to increase it 450 lbs using nine bags of play sand and the lathe's packing materials for the cabinetry. I'm guessing you could add 375 or even 400 lbs to the G0766 the same way.
As you continue your due diligence, you may want to ask if Grizzly has added a braking resistor to the Delta VFD this time around. Not a big deal, but it would be a nice touch. The G0733 did not come with one even though the drive has dedicated terminals for it. I added one for about $30, but it requires unlocking the drive and changing some of the parameters. Perhaps Grizzly has now done that at the factory.
I'm with John. I can't think of anyone better suited to write a review of the G0766 for TBN. :cool:
