Here are the SolidWorks files for my Grizzly G0602 DRO install. While these parts fairly well fit the 602 as is, it is prudent to check everything out before cutting. The were a couple of "adjustments" that had to be made. In particular, the "Lathe Cross Slide Scale Mount" "cross Feed Scale Mount R" were modified due to a miscalculation on cross slide travel. The design was intended to mirror the "Cross Feed Scale Mount L. and although it works as modeled, the model should be changed to reflect that. I believe that I also had to change the mounting hole location in the "Pickup Plate" as well. There were some features and minor engineering changes that didn't make it into the models also.
